IFSelect_Selection Class Referenceabstract

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 independant 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...

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. More...
 
Interface_EntityIterator UniqueResult (const Interface_Graph &G) const
 Returns the list of selected entities, each of them beeing unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph. More...

Detailed Description

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 independant 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 ouput. All list computations start from an input Graph (from IFGraph)

Member Function Documentation

◆ CompleteResult()

virtual Interface_EntityIterator IFSelect_Selection::CompleteResult ( const Interface_Graph G) const
virtual

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

Reimplemented in IFSelect_SelectModelEntities.

◆ FillIterator()

virtual void IFSelect_Selection::FillIterator ( IFSelect_SelectionIterator iter) const
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_SelectDeduct, IFSelect_SelectCombine, IFSelect_SelectControl, and IFSelect_SelectBase.

◆ HasUniqueResult()

virtual Standard_Boolean IFSelect_Selection::HasUniqueResult ( ) const
protectedvirtual

Returns True if RootResult guarantees uniqueness for each Entity. Called by UniqueResult. Default answer is False. Can be redefined.

Reimplemented in IFSelect_SelectCombine, IFSelect_SelectRootComps, IFSelect_SelectRoots, IGESSelect_SelectDrawingFrom, IGESSelect_SelectSingleViewFrom, IFSelect_SelectDiff, and STEPSelections_SelectInstances.

◆ Label()

virtual TCollection_AsciiString IFSelect_Selection::Label ( ) const
pure virtual

◆ RootResult()

virtual Interface_EntityIterator IFSelect_Selection::RootResult ( const Interface_Graph G) const
pure virtual

◆ UniqueResult()

Interface_EntityIterator IFSelect_Selection::UniqueResult ( const Interface_Graph G) const

Returns the list of selected entities, each of them beeing unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph.
