Role: A CELL2D is a maximal connected set of sheet faces that do not cross an edge that is adjacent to more than two faces (that is, a non-manifold edge). All constituent faces are double-sided, both-outside faces. The definition of a two-dimensional cell can be modified using the cell_granularity option. It is directly derived from CELL.
For additional information, refer to the Technical Article on Cellular Topology Data Structure.
| CELL2D::CELL2D | ( | ) |
C++ allocation constructor requests memory for this object but does not populate it.
Role: The allocation constructor is used primarily by restore. Applications should call this constructor only with the overloaded new operator inherited from the ENTITY class (for example, x=new CELL2D), because this reserves the memory on the heap, a requirement to support roll back and history management.
C++ initialize constructor requests memory for this object and populates it with the data supplied as arguments.
Role: Applications should call this constructor only with the overloaded new operator inherited from the ENTITY class (for example, x=new CELL2D(...)), because this reserves the memory on the heap, a requirement to support roll back and history management.
Initializes all the class data, and records the creation in the bulletin board. CFACE starts the lists of cshells contained in the cell, and CELL sets the pointer to the next cell in the owning lump. The constructor sets the backpointers in the cshells in the given list. The calling routine must set the lump which owns the cell using set_lump and, if desired, may set a bound using set_bound.
| list_cell | list of faces in cell. | |
| list_sibling | list of sibling cells. |
| virtual void ENTITY::add | ( | ) | [virtual, inherited] |
If this ENTITY is use counted, adds one to the count.
Role: If this ENTITY is not use counted, signals an error.
Every held pointer to a use counted ENTITY should be declared by calling add. There should a corresponding call to remove when the user is done with the pointer. For normal ENTITYs, simply call lose when the ENTITY is no longer part of the active model. For use counted ENTITYs, the implementations of add and remove come from macros in usecount.hxx. Use counted ENTITYs implemented without the macros should implement these virtual methods manually.
Reimplemented in CURVE, EE_LIST, SPAGROUP, PCURVE, PHLV5_OCC, APOINT, REFINEMENT, RH_MATERIAL, RH_TEXTURE_SPACE, SURFACE, and VERTEX_TEMPLATE.
| static MethodFunction CELL2D::add_method | ( | METHOD_ID const & | method_id, | |
| MethodFunction | method_func | |||
| ) | [static] |
Registers an implementation function for a run-time virtual method.
Role: (Supplied by the ENTITY_FUNCTIONS and UTILITY_DEF macros.)
| method_id | method id. | |
| method_func | method function. |
Reimplemented from CELL.
| virtual logical ENTITY::apply_transform | ( | const SPAtransf & | t, | |
| ENTITY_LIST & | list, | |||
| logical | negate = FALSE, |
|||
| logical | reset_pattern = TRUE | |||
| ) | [virtual, inherited] |
Transforms this ENTITY.
Role: The ENTITY_LIST is used to prevent sub-entities from being transformed more than once. This method is not included with the standard ENTITY methods in order to allow nontransformable ENTITYs to use the default implementation. (Supplied by the TRANSFORM_FUNCTION and TRANSFORM_DEF macros.)
| t | the transform to apply. | |
| list | list of entities to which the transform has already been applied. | |
| negate | negation flag. | |
| reset_pattern | internal use only. |
Reimplemented in ASM_ASSEMBLY, ASM_MODEL_REF, BODY, COEDGE, CURVE, EDGE, ERROR_ENTITY, FACE, LAW, LOOP, LUMP, APATTERN, PCURVE, APOINT, SHELL, SUBSHELL, SURFACE, TCOEDGE, TEDGE, TEXT_ENT, TVERTEX, VERTEX, WCS, and WIRE.
| ATTRIB* ENTITY::attrib | ( | ) | const [inline, inherited] |
Returns this ENTITY's attribute pointer, or NULL if there is no attached attribute.
| ENTITY* ENTITY::backup | ( | ) | [inherited] |
Creates a duplicate record and a change bulletin, if needed, as a backup for roll back.
Role: The duplication is done via the virtual function make_copy, to let each derived type do its own backup. Before performing a change, each routine checks whether the data structure is posted on the bulletin board. If not, the posting is done automatically. Called by all system change functions.
| SPAbox* CELL::bound | ( | ) | const [inline, inherited] |
Returns the bound pointer.
| int ENTITY::bulletin_count | ( | ) | const [inline, inherited] |
Returns the number of bulletins referring to this ENTITY.
| virtual logical ENTITY::bulletin_no_change_vf | ( | const ENTITY * | other, | |
| logical | identical_comparator | |||
| ) | const [protected, virtual, inherited] |
Compares subclass data.
Role: This virtual method is called by bulletin_no_change. When the identical_comparator argument is TRUE, it requires an exact match when comparing doubles, and returns the result of memcmp as a default (for non-overridden subclasses). A FALSE argument indicates tolerant compares, in which case FALSE is returned by default.
| other | other ENTITY in the bulletin. | |
| identical_comparator | identity compare flag. |
Reimplemented in BODY, COEDGE, CONE, CURVE, EDGE, ELLIPSE, FACE, HELIX, INTCURVE, LOOP, LUMP, PCURVE, PLANE, APOINT, SHELL, SPHERE, SPLINE, STRAIGHT, SUBSHELL, SURFACE, TCOEDGE, TEDGE, TORUS, TVERTEX, UNDEFC, VERTEX, and WIRE.
| virtual logical CELL2D::call_method | ( | METHOD_ID const & | method_id, | |
| METHOD_ARGS const & | method_args | |||
| ) | [virtual] |
Executes the implementation function for a routine virtual method.
Role: (Supplied by the ENTITY_FUNCTIONs and UTILITY_DEF macros).
| method_id | method id. | |
| method_args | method args. |
Reimplemented from CELL.
| CFACE* CELL2D::cface | ( | ) | const [inline] |
Returns the pointer to the list of cfaces that comprise the cell.
| void ENTITY::check_destroy | ( | ) | const [inline, protected, inherited] |
Checks that entity deletion is legitimate.
Role: This method complains if there is an attempt to delete an entity other than through the private member function destroy, which is carefully controlled.
| void ENTITY::copy_common | ( | ENTITY_LIST & | list, | |
| const ENTITY * | from, | |||
| pointer_map * | pm = NULL, |
|||
| logical | dpcpy_skip = FALSE, |
|||
| SCAN_TYPE | reason = SCAN_COPY | |||
| ) | [protected, inherited] |
Fills in this ENTITY with data from the copied ENTITY, converting pointers into indices in the supplied ENTITY_LIST.
Role: Supports the copy operation. (Supplied by the ENTITY_FUNCTIONS and COPY_DEF macros.) Whenever the operation encounters a pointer to a dependent ENTITY, it find the index of the latter in the supplied ENTITY_LIST and sets the corresponding pointer in the copy to that index.
| list | list of ENTITYs being copied. | |
| from | original ENTITY being copied. | |
| pm | pointer map. | |
| dpcpy_skip | Used only by the base ENTITY and base ATTRIB class. No other derived entity or attribute should need to utilize this value. This logical indicates how non- deepcopyable attributes are handled during a deep copy. If TRUE, the copy will continue even if it encounters attributes marked as not deep-copyable. By default (FALSE), if any attributes that are found to be not deep-copyable, a sys_error will be thrown. (This flag only effects how attributes are handled; any non-deepcopyable non-attribute entities encountered will cause a sys_error to be thrown regardless of this flag's setting.) | |
| reason | type of scan. |
| virtual ENTITY* CELL2D::copy_data | ( | ENTITY_LIST & | list, | |
| pointer_map * | pm = NULL, |
|||
| logical | dpcpy_skip = FALSE, |
|||
| SCAN_TYPE | reason = SCAN_COPY | |||
| ) | const [virtual] |
Allocates a new ENTITY and calls copy_common to fill it in.
Role: Supports the copy operation. (Supplied by the ENTITY_FUNCTIONS and UTILITY_DEF macros.)
| list | ENTITYs to copy. | |
| pm | pointer map. | |
| dpcpy_skip | Used only by the base ENTITY and base ATTRIB class. No other derived entity or attribute should need to utilize this value. This logical indicates how non- deepcopyable attributes are handled during a deep copy. If TRUE, the copy will continue even if it encounters attributes marked as not deep-copyable. By default (FALSE), if any attributes that are found to be not deep-copyable, a sys_error will be thrown. (This flag only effects how attributes are handled; any non-deepcopyable non-attribute entities encountered will cause a sys_error to be thrown regardless of this flag's setting.) | |
| reason | scan type. |
Reimplemented from CELL.
| virtual void CELL2D::copy_scan | ( | ENTITY_LIST & | list, | |
| SCAN_TYPE | reason = SCAN_COPY, |
|||
| logical | dpcpy_skip = FALSE | |||
| ) | const [virtual] |
Adds dependent ENTITYs of this ENTITY to the list of ENTITYs to be copied.
Role: Supports the copy operation. (Supplied by the ENTITY_FUNCTIONS and SCAN_DEF macros.) The default type of scan (reason) is SCAN_COPY.
| list | ENTITYs to copy. | |
| reason | type of copy. | |
| dpcpy_skip | Used only by the base ENTITY and base ATTRIB class. No other derived entity or attribute should need to utilize this value. This logical indicates how non- deepcopyable attributes are handled during a deep copy. If TRUE, the copy will continue even if it encounters attributes marked as not deep-copyable. By default (FALSE), if any attributes that are found to be not deep-copyable, a sys_error will be thrown. (This flag only effects how attributes are handled; any non-deepcopyable non-attribute entities encountered will cause a sys_error to be thrown regardless of this flag's setting.) |
Reimplemented from CELL.
| virtual void CELL2D::debug_ent | ( | FILE * | file_pointer | ) | const [virtual] |
Prints the type and address of this ENTITY, roll back pointer, attributes, and any unknown subtype information.
Role: This method is called by DEBUG_LIST::debug for an entirely unknown ENTITY type, or at the start of any derived class's debug_ent method. Each derived class's debug_ent method uses the debug function described in the Spatial Product Documentation to print information added at that level. (Supplied by the ENTITY_FUNCTIONS and DEBUG_DEF macros.)
| file_pointer | file pointer. |
Reimplemented from CELL.
| virtual logical CELL::deletable | ( | ) | const [virtual, inherited] |
Converts pointers from copy indices into real pointers.
Role: Called by fix_pointers. For ENTITY, converts the attribute pointer, and any pointers in the unknown_entity_text record. (Supplied by the ENTITY_FUNCTIONS and FIX_POINTER_DEF macros.)
| array | ENTITY pointers to fix. | |
| reason | type of scan. |
Reimplemented from CELL.
| virtual void CELL2D::fix_pointers | ( | ENTITY * | entity_array[], | |
| SCAN_TYPE | reason = SCAN_COPY | |||
| ) | [virtual] |
Converts pointers from copy indices into real pointers.
Role: The fix_pointers method for each entity in the restore array is called, with the given array as an argument. This calls fix_common, which calls its parent's fix_common, and then corrects any pointers in the derived class. In practice there is never anything special for fix_pointers to do, but it is retained for consistency and compatibility. (Supplied by the ENTITY_FUNCTIONS and UTILITY_DEF macros.)
| entity_array | ENTITY pointers to fix. | |
| reason | type of scan. |
Reimplemented from CELL.
| void ENTITY::fixup_copy | ( | ENTITY * | rollback | ) | const [protected, inherited] |
Fixes any pointers in the ENTITY after copying for backup.
Role: For ENTITY, this method has nothing to do, but because it is called by all data types, it is required to terminate the copy chain. (Supplied by the ENTITY_FUNCTIONS and SIMPLE_COPY_CONE macros.)
| rollback | the ENTITY to copy for backup. |
Reimplemented in GA_WORKSPACE.
| virtual void CELL::full_size | ( | SizeAccumulator & | est, | |
| logical | countSelf | |||
| ) | const [protected, virtual, inherited] |
Increments the SizeAccumulator by the size, in bytes, of everything owned by this ENTITY and, optionally, of the ENTITY itself.
Role: If countSelf is TRUE, increments the SizeAccumulator by the size, in bytes, of the ENTITY and everything owned by the ENTITY. If countSelf is FALSE, increments the SizeAccumulator by the size, in bytes, of everything owned by the ENTITY, but not including the size of the ENTITY itself.
For example, if an ENTITY contained a character string and full_size were called with countSelf == FALSE, the SizeAccumulator would be incremented by the size, in bytes, of the character string.
Reimplemented from ENTITY.
| HISTORY_STREAM* ENTITY::history | ( | ) | const [inline, inherited] |
Returns a pointer to the history stream for this ENTITY.
| virtual logical ENTITY::holds_pattern | ( | ) | const [inline, protected, virtual, inherited] |
| virtual int CELL2D::identity | ( | int | level = 0 |
) | const [virtual] |
Returns a type identifier for this ENTITY.
Role: If level is unspecified or 0, returns the type identifier ENTITY_TYPE. If level is specified, returns ENTITY_TYPE for that level of derivation from ENTITY. The level of this class is defined as ENTITY_LEVEL.
A positive level specifies the level of derivation down from the ENTITY class to examine. ENTITY itself has level 0. If level is unspecified or 0, the type of the most specific class of object is returned. If level is 1, the type of the class one level down from ENTITY is returned. If level is 2, the type of the parent class 2 levels down from ENTITY is returned, and so on. If level is greater than the level of the instance, -1 ("unknown") is returned.
A negative level similarly specifies the level of derivation up from the most specific class of object returned.
(Supplied by the ENTITY_FUNCTIONS and UTILITY_DEF macros.)
| level | the derivation level at which the object is to be identified. |
Reimplemented from CELL.
| void CELL::invalidate | ( | ) | [inherited] |
Invalidates the update data.
| virtual logical CELL2D::is_deepcopyable | ( | ) | const [virtual] |
| logical ENTITY::is_unknown_entity | ( | void | ) | const [protected, inherited] |
Returns TRUE if this is an unknown entity.
An unknown entity is one that is restored from SAT/SAB but is not native to the running app.
| virtual logical ENTITY::is_use_counted | ( | ) | const [virtual, inherited] |
Indicates if this ENTITY is use-counted or not.
Role: The default implementation returns FALSE.
Reimplemented in CURVE, PCURVE, PHLV5_OCC, APOINT, REFINEMENT, RH_MATERIAL, RH_TEXTURE_SPACE, SURFACE, and VERTEX_TEMPLATE.
| void CELL::kill_bound | ( | ) | [inline, protected, inherited] |
Sets the bounding pointer to NULL.
| virtual int CELL2D::lookup | ( | logical | insert | ) | const [virtual] |
Looks up this ENTITY in the appropriate debug list.
Role: This method is not included among the standard ENTITY methods because often subclasses may wish to be included in their parent's debug list. This is done simply by not including a lookup method in the subclass.
When the logical argument is TRUE, the ENTITY is inserted into the debug list if it does not already exist in the list. If it is FALSE and the ENTITY does not exist in the list, a -1 is returned. (Supplied by the LOOK_FUNCTION and LOOKUP_DEF macros.)
| insert | flag to insert into debug list. |
Reimplemented from CELL.
| virtual void CELL2D::lose | ( | ) | [virtual] |
Posts a delete bulletin to the bulletin board indicating the instance is no longer used in the active model.
Role: The lose methods for attached attributes are also called.
Reimplemented from CELL.
| LUMP* CELL::lump | ( | ) | const [inline, inherited] |
Returns the pointer to the owning lump.
| logical ENTITY::needs_rollback | ( | ) | const [inline, inherited] |
Checks whether or not the record is already backed up.
| CELL* CELL::next | ( | ) | const [inherited] |
Returns the pointer to the next cell in a complete enumeration of all the cells owned by the lump.
| CELL* CELL::next_in_list | ( | ) | const [inline, inherited] |
Returns a pointer to the next cell in the list maintained by an ATTRIB_CELL or a SUPERCELL.
| virtual ENTITY* CELL::owner | ( | ) | const [inline, virtual, inherited] |
| virtual void ENTITY::remove | ( | logical | lose_if_zero = TRUE |
) | [virtual, inherited] |
Decrements the use count of this ENTITY.
Role: If the use count reaches 0, the ENTITY's lose method is called if the argument lose_if_zero is set to TRUE. (If the entity is not use counted, an error is signaled.)
Every held pointer to a use counted ENTITY should be declared by calling add. There should a corresponding call to remove when the user is done with the pointer. For normal ENTITYs, simply call lose when the ENTITY is no longer part of the active model. For use counted ENTITYs, the implementations of add and remove come from macros in usecount.hxx. Use counted ENTITYs implemented without the macros should implement these virtual methods manually.
| lose_if_zero | flag to lose the ENTITY when the use count drops to 0. |
Reimplemented in CURVE, SPAGROUP, PCURVE, PHLV5_OCC, APOINT, REFINEMENT, RH_MATERIAL, RH_TEXTURE_SPACE, SURFACE, and VERTEX_TEMPLATE.
| void CELL2D::restore_common | ( | ) |
Restores data for a record from disc to memory.
Role: Writes pointers as indices (fix_pointers turns them back into pointers) and returns a pointer to the ENTITY made. Generally, "common" functions that do the main work are protected, as they are called only from the main entry functions or by themselves up the derivation tree.
This method is public, however, because the main restore function is not a member function, and making it a friend would make it unable to be declared static, i.e., local to the defining module. (Supplied by the ENTITY_FUNCTIONS and RESTORE_DEF macros.)
read_ptr Pointer to record in save file for first attribute owned by entity.
if (restore_version_number >= ENTITY_TAGS_VERSION)
read_int new tag
Reimplemented from CELL.
| void ENTITY::restore_end | ( | char * | id_str | ) | [inherited] |
Terminates a restore record.
Role: Reads any trailing text and fills in the unknown text pointer. Used only by the save/restore system.
| id_str | the id string. |
| virtual void ENTITY::roll_notify | ( | BULLETIN_TYPE | bulletin_type, | |
| ENTITY * | ent | |||
| ) | [protected, virtual, inherited] |
Fields notifications of rollback operations.
Role: The first argument specifies the type of bulletin being rolled back (create, delete or change). In the case of a change notification, the second argument contains the information to be restored into this object. The base implementation, which is used for almost every derived class, does nothing at all.
| bulletin_type | type of bulletin being rolled back. | |
| ent | information to be restored into this argument. |
Reimplemented in ANNOTATION, ASM_MODEL_REF, ATTRIB_INTCOED, ATTRIB_EFINT, ATTRIB_FFBLEND, ATTRIB_CONST_CHAMFER, COEDGE, ATTRIB_COL, CURVE, ATTRIB_DM2ACIS, EDGE, EE_LIST, FACE, GA_WORKSPACE, ID_ATTRIB, LOOP, ATTRIB_EYE_ATTACHED_MESH, PCURVE, PHLV5_OCC, APOINT, REFINEMENT, ATTRIB_RGB, RH_MATERIAL, RH_LIGHT, RH_BACKGROUND, RH_FOREGROUND, RH_TEXTURE_SPACE, SURFACE, TCOEDGE, TEDGE, TVERTEX, ATTRIB_VAR_BLEND, VERTEX, VERTEX_TEMPLATE, and WCS.
| BULLETIN*& ENTITY::rollback | ( | ) | const [inline, inherited] |
Returns the pointer to the bulletin board entry for this ENTITY.
| virtual void CELL2D::save | ( | ENTITY_LIST & | entity_list | ) | const [virtual] |
Performs a save operation.
Role: Calls save_begin, the particular class's save_common, and then save_end. (Supplied by the ENTITY_FUNCTIONS and UTILITY_DEF macros.)
This save method is just like any other save, except that it calls save_begin with an optional argument to suppress writing of a trailing dash, because save_common does not write out an identifier, or call any parent class's save_common.
| entity_list | ENTITYs to save. |
Reimplemented from CELL.
| void ENTITY::save_begin | ( | logical | terminator = FALSE |
) | const [protected, inherited] |
Starts a save record.
Role: Writes a preamble to a save file record, which contains any subclass identifiers not known to this version of ACIS. Called by the save method.
| terminator | terminator flag. |
| void CELL2D::save_common | ( | ENTITY_LIST & | entity_list | ) | const [protected] |
Handles the save operation.
Role: Writes out the savable data associated with the base class. In the case of ENTITY, saveable data is simply the attribute pointer. In the case of child classes derived from ENTITY, class-specific save_common methods handle the class-specific data. Called by the save method. (Supplied by the ENTITY_FUNCTIONS and SAVE_DEF macros.)
Each derived class's save_common method first writes out that class's identifier, calls its parent class's save_common method, and then writes out data particular to the derived class. Thus the save record consists of identifiers in leaf-to-base order, followed by class data in base-to-leaf order. As it writes out any ENTITY pointers, it adds them to the ENTITY_LIST, so that any dependent data also gets written to the file.
| entity_list | ENTITYs to save |
Reimplemented from CELL.
| void ENTITY::save_end | ( | ENTITY_LIST & | list | ) | const [protected, inherited] |
Terminates a save record.
Role: Writes out any data associated with subclasses not known to this version of ACIS before terminating the record. Called by the save method.
| list | list of entities. |
| void ENTITY::set_attrib | ( | ATTRIB * | attr | ) | [inherited] |
Changes the attribute pointer of this ENTITY to point to the given attribute.
| attr | the new attribute. |
| void CELL::set_bound | ( | SPAbox * | ) | [inherited] |
Changes the data for the bounding box.
Role: This method checks that the record has been posted on the bulletin board before performing the change. If not, the method returns an error, so that the omission (forgetting to call backup first) can be rectified in the program.
| SPAbox | bounding box. |
| void CELL2D::set_cface | ( | CFACE * | cface | ) |
| void CELL::set_lump | ( | LUMP * | ) | [inherited] |
Changes the pointer to the owning lump.
Role: This method checks that the record has been posted on the bulletin board before performing the change. If not, the method returns an error, so that the omission (forgetting to call backup first) can be rectified in the program.
| LUMP | lump. |
| void CELL::set_next | ( | CELL * | ) | [inherited] |
Changes the pointer to the next cell.
Role: This method checks that the record has been posted on the bulletin board before performing the change. If not, the method returns an error, so that the omission (forgetting to call backup first) can be rectified in the program.
| CELL | cell. |
| void CELL::set_supercell | ( | SUPERCELL * | ) | [inherited] |
Changes the pointer an owning supercell.
(Usually there are no supercells.)
Role: This method checks that the record has been posted on the bulletin board before performing the change. If not, the method returns an error, so that the omission (forgetting to call backup to call backup first) can be rectified in the program.
| SUPERCELL | supercell. |
| virtual void ENTITY::set_use_count | ( | int | use | ) | [virtual, inherited] |
Sets the reference use count of this ENTITY.
Role: If the ENTITY is not use counted, this method does nothing.
| use | new use count. |
Reimplemented in CURVE, PCURVE, PHLV5_OCC, APOINT, REFINEMENT, RH_MATERIAL, RH_TEXTURE_SPACE, SURFACE, and VERTEX_TEMPLATE.
