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...

Interface_EntityIterator | UniqueResult (const Interface_Graph &G) const

## 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

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.

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.

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.

virtual TCollection_AsciiString IFSelect_Selection::Label | ( |  | ) | const
| pure virtual

Returns a text which defines the criterium applied by a Selection (can be used to be printed, displayed ...) Specific to each class.

Implemented in IFSelect_SelectPointed, IFSelect_SelectAnyList, IFSelect_SelectSuite, IFSelect_SelectExplore, IFSelect_SelectExtract, IFSelect_SelectEntityNumber, IFSelect_SelectModelEntities, IGESSelect_SelectDrawingFrom, IGESSelect_SelectFromDrawing, IGESSelect_SelectFromSingleView, IGESSelect_SelectSingleViewFrom, IFSelect_SelectModelRoots, IFSelect_SelectSharing, IFSelect_SelectDiff, IFSelect_SelectIntersection, IFSelect_SelectShared, and IFSelect_SelectUnion.

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

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.

Implemented in IFSelect_SelectPointed, IFSelect_SelectAnyList, IFSelect_SelectSuite, IFSelect_SelectSent, IFSelect_SelectExplore, IFSelect_SelectFlag, IFSelect_SelectExtract, IFSelect_SelectRootComps, IFSelect_SelectEntityNumber, IFSelect_SelectRoots, IGESSelect_SelectDrawingFrom, IGESSelect_SelectFromDrawing, IGESSelect_SelectFromSingleView, IGESSelect_SelectSingleViewFrom, IFSelect_SelectModelRoots, IFSelect_SelectSharing, IFSelect_SelectDiff, IFSelect_SelectIntersection, IFSelect_SelectModelEntities, IFSelect_SelectShared, IFSelect_SelectUnion, STEPSelections_SelectInstances, and STEPSelections_SelectForTransfer.

Interface_EntityIterator IFSelect_Selection::UniqueResult | ( | const Interface_Graph & | G | ) | const
