IFSelect_SelectExtract Class Referenceabstract

A SelectExtract determines a list of Entities from an Input Selection, as a sub-list of the Input Result It works by applying a sort criterium on each Entity of the Input. This criterium can be applied Direct to Pick Items (default case) or Reverse to Remove Item. More...

Detailed Description

A SelectExtract determines a list of Entities from an Input Selection, as a sub-list of the Input Result It works by applying a sort criterium on each Entity of the Input. This criterium can be applied Direct to Pick Items (default case) or Reverse to Remove Item.

Basic features (the unique Input) are inherited from SelectDeduct

Constructor & Destructor Documentation

◆ IFSelect_SelectExtract()

IFSelect_SelectExtract::IFSelect_SelectExtract ( )
protected

Initializes a SelectExtract : enforces the sort to be Direct.

Member Function Documentation

◆ ExtractLabel()

virtual TCollection_AsciiString IFSelect_SelectExtract::ExtractLabel ( ) const
pure virtual

◆ IsDirect()

Standard_Boolean IFSelect_SelectExtract::IsDirect ( ) const

Returns True if Sort criterium is Direct, False if Reverse.

◆ Label()

TCollection_AsciiString IFSelect_SelectExtract::Label ( ) const
overridevirtual

Returns a text saying "Picked" or "Removed", plus the specific criterium returned by ExtractLabel (see below)

Implements IFSelect_Selection.

◆ RootResult()

virtual Interface_EntityIterator IFSelect_SelectExtract::RootResult ( const Interface_Graph G) const
overridevirtual

Returns the list of selected entities. Works by calling the method Sort on each input Entity : the Entity is kept as output if Sort returns the same value as Direct status.

Implements IFSelect_Selection.

Reimplemented in IFSelect_SelectSent, IFSelect_SelectFlag, IFSelect_SelectRootComps, IFSelect_SelectRoots, and STEPSelections_SelectForTransfer.

◆ SetDirect()

void IFSelect_SelectExtract::SetDirect ( const Standard_Boolean  direct)

Sets Sort criterium sense to a new value (True : Direct , False : Reverse)

◆ Sort()

virtual Standard_Boolean IFSelect_SelectExtract::Sort ( const Standard_Integer  rank,
const Handle< Standard_Transient > &  ent,
const Handle< Interface_InterfaceModel > &  model 
) const
pure virtual

Returns True for an Entity if it satisfies the Sort criterium It receives :

  • <rank>, the rank of the Entity in the Iteration,
  • <ent> , the Entity itself, and
  • <model>, the Starting Model Hence, the Entity to check is "model->Value(num)" (but an InterfaceModel allows other checks) This method is specific to each class of SelectExtract

Implemented in IFSelect_SelectSignature, XSControl_SelectForTransfer, IFSelect_SelectRange, IFSelect_SelectSent, IFSelect_SelectFlag, IGESSelect_SelectLevelNumber, IGESSelect_SelectSubordinate, IFSelect_SelectRootComps, IFSelect_SelectRoots, IGESSelect_SelectName, IFSelect_SelectErrorEntities, IFSelect_SelectAnyType, IFSelect_SelectUnknownEntities, and IGESSelect_SelectVisibleStatus.

◆ SortInGraph()

virtual Standard_Boolean IFSelect_SelectExtract::SortInGraph ( const Standard_Integer  rank,
const Handle< Standard_Transient > &  ent,
const Interface_Graph G 
) const
virtual

Works as Sort but works on the Graph Default directly calls Sort, but it can be redefined If SortInGraph is redefined, Sort should be defined even if not called (to avoid deferred methods in a final class)

Reimplemented in IFSelect_SelectSignature.
