# IFSelect_Selection Class Reference

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)
.

## Public Member Functions

virtual Standard_EXPORT 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 .
Standard_EXPORT 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. .
virtual Standard_EXPORT 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 Standard_EXPORT 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 Standard_EXPORT 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 .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const

## Protected Member Functions

virtual Standard_EXPORT Standard_Boolean | HasUniqueResult () const
| Returns True if RootResult guarantees uniqueness for each Entity. Called by UniqueResult. Default answer is False. Can be redefined. .
