DEFINE_STANDARD_ALLOC Interface_EntityIterator ()
 Defines an empty iterator (see AddList & AddItem)

 Interface_EntityIterator (const Handle< TColStd_HSequenceOfTransient > &list)
 Defines an iterator on a list, directly i.e. without copying it

void AddList (const Handle< TColStd_HSequenceOfTransient > &list)
 Gets a list of entities and adds its to the iteration list

void AddItem (const Handle< Standard_Transient > &anentity)
 Adds to the iteration list a defined entity

void GetOneItem (const Handle< Standard_Transient > &anentity)
 same as AddItem (kept for compatibility)

void SelectType (const Handle< Standard_Type > &atype, const Standard_Boolean keep)
 Selects entities with are Kind of a given type, keep only
them (is keep is True) or reject only them (if keep is False)

Standard_Integer NbEntities () const
 Returns count of entities which will be iterated on
Calls Start if not yet done

Standard_Integer NbTyped (const Handle< Standard_Type > &type) const
 Returns count of entities of a given type (kind of)

Interface_EntityIterator Typed (const Handle< Standard_Type > &type) const
 Returns the list of entities of a given type (kind of)

virtual void Start () const
 Allows re-iteration (useless for the first iteration)

Standard_Boolean More () const
 Says if there are other entities (vertices) to iterate
the first time, calls Start

void Next () const
 Sets iteration to the next entity (vertex) to give

const Handle_Standard_TransientValue () const
 Returns the current Entity iterated, to be used by Interface
tools or by GraphTools (where Entity is a Vertex)

Handle_TColStd_HSequenceOfTransient Content () const
 Returns the content of the Iterator, accessed through a Handle
to be used by a frontal-engine logic
Returns an empty Sequence if the Iterator is empty
Calls Start if not yet done

virtual void Destroy ()
 Clears data of iteration

virtual ~Interface_EntityIterator ()

Protected Member Functions

void Reset ()
 Allows subclasses of EntityIterator to reevaluate an iteration
