Detailed Description

A SelectDeduct determines a list of Entities from an Input Selection, by a computation : Output list is not obliged to be a sub-list of Input list (for more specific, see SelectExtract for filtered sub-lists, and SelectExplore for recurcive exploration)

A SelectDeduct may use an alternate input for one shot This allows to use an already existing definition, by overloading the input selection by an alternate list, already defined, for one use : If this alternate list is set, InputResult queries it instead of calling the input selection, then clears it immediately

Member Function Documentation

◆ Alternate()

Handle< IFSelect_SelectPointed >& IFSelect_SelectDeduct::Alternate ( )

Returns the Alternate Definition It is returned modifiable, hence an already defined SelectPointed can be used But if it was not yet defined, it is created the first time.

It is exploited by InputResult

◆ FillIterator()

void IFSelect_SelectDeduct::FillIterator ( IFSelect_SelectionIterator iter) const
overridevirtual

Puts in an Iterator the Selections from which "me" depends This list contains one Selection : the InputSelection.

Implements IFSelect_Selection.

◆ HasAlternate()

Standard_Boolean IFSelect_SelectDeduct::HasAlternate ( ) const

Tells if an Alternate List has been set, i.e. : the Alternate Definition is present and set.

◆ HasInput()

Standard_Boolean IFSelect_SelectDeduct::HasInput ( ) const

Returns True if the Input Selection is defined, False else.

◆ Input()

Handle< IFSelect_Selection > IFSelect_SelectDeduct::Input ( ) const

Returns the Input Selection.

◆ InputResult()

Interface_EntityIterator IFSelect_SelectDeduct::InputResult ( const Interface_Graph G) const

Returns the Result determined by Input Selection, as Unique if Input Selection is not defined, returns an empty list.

If Alternate is set, InputResult takes its definition instead of calling the Input Selection, then clears it

◆ SetInput()

void IFSelect_SelectDeduct::SetInput ( const Handle< IFSelect_Selection > &  sel)

Defines or Changes the Input Selection.
