IFSelect_SelectRootComps Class Reference

A SelectRootComps sorts the Entities which are part of Strong Components, local roots of a set of Entities : they can be Single Components (containing one Entity) or Cycles This class gives a more secure result than SelectRoots (which considers only Single Components) but is longer to work : it can be used when there can be or there are cycles in a Model For each cycle, one Entity is given arbitrarily Reject works as for SelectRoots : Strong Components defined in the input list which are not local roots are given.

Public Member Functions

 IFSelect_SelectRootComps ()
 Creates a SelectRootComps.
 
virtual Interface_EntityIterator RootResult (const Interface_Graph &G) const override
 Returns the list of local root strong components, by one Entity per component. It is redefined for a purpose of efficiency : calling a Sort routine for each Entity would cost more resources than to work in once using a Map RootResult takes in account the Direct status.
 
Standard_Boolean Sort (const Standard_Integer rank, const Handle< Standard_Transient > &ent, const Handle< Interface_InterfaceModel > &model) const override
 Returns always True, because RootResult has done work.
 
TCollection_AsciiString ExtractLabel () const override
 Returns a text defining the criterium : "Local Root Components".
 
- Public Member Functions inherited from IFSelect_SelectExtract
Standard_Boolean IsDirect () const
 Returns True if Sort criterium is Direct, False if Reverse.
 
void SetDirect (const Standard_Boolean direct)
 Sets Sort criterium sense to a new value (True : Direct , False : Reverse)
 
virtual Standard_Boolean SortInGraph (const Standard_Integer rank, const Handle< Standard_Transient > &ent, const Interface_Graph &G) const
 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)
 
TCollection_AsciiString Label () const override
 Returns a text saying "Picked" or "Removed", plus the specific criterium returned by ExtractLabel (see below)
 
- Public Member Functions inherited from IFSelect_SelectDeduct
void SetInput (const Handle< IFSelect_Selection > &sel)
 Defines or Changes the Input Selection.
 
Handle< IFSelect_SelectionInput () const
 Returns the Input Selection.
 
Standard_Boolean HasInput () const
 Returns True if the Input Selection is defined, False else.
 
Standard_Boolean HasAlternate () const
 Tells if an Alternate List has been set, i.e. : the Alternate Definition is present and set.
 
Handle< IFSelect_SelectPointed > & 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.
 
Interface_EntityIterator 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.
 
void FillIterator (IFSelect_SelectionIterator &iter) const override
 Puts in an Iterator the Selections from which "me" depends This list contains one Selection : the InputSelection.
 
- Public Member Functions inherited from IFSelect_Selection
Interface_EntityIterator UniqueResult (const Interface_Graph &G) const
 Returns the list of selected entities, each of them being unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph.
 
virtual 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)
 
- Public Member Functions inherited from Standard_Transient
 Standard_Transient ()
 Empty constructor.
 
 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (const Standard_Transient &)
 Assignment operator, needed to avoid copying reference counter.
 
virtual ~Standard_Transient ()
 Destructor must be virtual.
 
virtual const opencascade::handle< Standard_Type > & DynamicType () const
 Returns a type descriptor about this object.
 
Standard_Boolean IsInstance (const opencascade::handle< Standard_Type > &theType) const
 Returns a true value if this is an instance of Type.
 
Standard_Boolean IsInstance (const Standard_CString theTypeName) const
 Returns a true value if this is an instance of TypeName.
 
Standard_Boolean IsKind (const opencascade::handle< Standard_Type > &theType) const
 Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
 
Standard_Boolean IsKind (const Standard_CString theTypeName) const
 Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
 
Standard_TransientThis () const
 Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
 
Standard_Integer GetRefCount () const noexcept
 Get the reference counter of this object.
 
void IncrementRefCounter () noexcept
 Increments the reference counter of this object.
 
Standard_Integer DecrementRefCounter () noexcept
 Decrements the reference counter of this object; returns the decremented value.
 
virtual void Delete () const
 Memory deallocator for transient classes.

Detailed Description

A SelectRootComps sorts the Entities which are part of Strong Components, local roots of a set of Entities : they can be Single Components (containing one Entity) or Cycles This class gives a more secure result than SelectRoots (which considers only Single Components) but is longer to work : it can be used when there can be or there are cycles in a Model For each cycle, one Entity is given arbitrarily Reject works as for SelectRoots : Strong Components defined in the input list which are not local roots are given.
