A Selection allows to define a set of Interface Entities. Entities to be put on an output file should be identified in a way as independent from such or such execution as possible. This permits to handle comprehensive criteria, and to replay them when a new variant of an input file has to be processed. More...

Public Member Functions | |
| virtual Interface_EntityIterator | RootResult (const Interface_Graph &G) const =0 |
| Returns the list of selected entities, computed from Input given as a Graph. Specific to each class of Selection Note that uniqueness of each entity is not required here This method can raise an exception as necessary. | |
| Interface_EntityIterator | UniqueResult (const Interface_Graph &G) const |
| Returns the list of selected entities, each of them being unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph. | |
| virtual Interface_EntityIterator | CompleteResult (const Interface_Graph &G) const |
| Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not) | |
| virtual void | FillIterator (IFSelect_SelectionIterator &iter) const =0 |
| Puts in an Iterator the Selections from which "me" depends (there can be zero, or one, or a list). Specific to each class of Selection. | |
| virtual TCollection_AsciiString | Label () const =0 |
| Returns a text which defines the criterium applied by a Selection (can be used to be printed, displayed ...) Specific to each class. | |
 Public Member Functions inherited from Standard_Transient | |
| Standard_Transient () | |
| Empty constructor. | |
| Standard_Transient (const Standard_Transient &) | |
| Copy constructor – does nothing. | |
| Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. | |
| virtual | ~Standard_Transient ()=default |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| bool | IsInstance (const char *const theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| bool | IsKind (const opencascade::handle< Standard_Type > &theType) const |
| Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| bool | IsKind (const char *const theTypeName) const |
| Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| Standard_Transient * | This () const |
| Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. | |
| int | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |
| int | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |
Protected Member Functions | |
| virtual bool | HasUniqueResult () const |
| Returns True if RootResult guarantees uniqueness for each Entity. Called by UniqueResult. Default answer is False. Can be redefined. | |
Additional Inherited Members | |
| Public Types inherited from Standard_Transient | |
| typedef void | base_type |
| Returns a type descriptor about this object. | |
| Static Public Member Functions inherited from Standard_Transient | |
| static constexpr const char * | get_type_name () |
| Returns a type descriptor about this object. | |
| static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
| Returns type descriptor of Standard_Transient class. | |
A Selection allows to define a set of Interface Entities. Entities to be put on an output file should be identified in a way as independent from such or such execution as possible. This permits to handle comprehensive criteria, and to replay them when a new variant of an input file has to be processed.
Its input can be, either an Interface Model (the very source), or another-other Selection(s) or any other output. All list computations start from an input Graph (from IFGraph)

virtual |
Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not)
Reimplemented in IFSelect_SelectModelEntities.

pure virtual |
Puts in an Iterator the Selections from which "me" depends (there can be zero, or one, or a list). Specific to each class of Selection.
Implemented in IFSelect_SelectBase, IFSelect_SelectCombine, IFSelect_SelectControl, and IFSelect_SelectDeduct.
Returns True if RootResult guarantees uniqueness for each Entity. Called by UniqueResult. Default answer is False. Can be redefined.
Reimplemented in IGESSelect_SelectDrawingFrom, IGESSelect_SelectSingleViewFrom, STEPSelections_SelectInstances, IFSelect_SelectCombine, IFSelect_SelectDiff, IFSelect_SelectRootComps, and IFSelect_SelectRoots.
