class EntityIterator from Interface
|
|
|
|
---Purpose : Defines an Iterator on Entities, complying with GraphTools
|
|
-- needs. Allows considering of various criteria
|
|
|
|
uses Transient, HSequenceOfTransient from TColStd,
|
|
IntVal, InterfaceModel
|
|
|
|
raises NoMoreObject, NoSuchObject
|
|
|
|
is
|
|
|
|
Create returns EntityIterator;
|
|
---Purpose : Defines an empty iterator (see AddList & AddItem)
|
|
|
|
Create (list : HSequenceOfTransient) returns EntityIterator;
|
|
---Purpose : Defines an iterator on a list, directly i.e. without copying it
|
|
|
|
AddList (me : in out; list : HSequenceOfTransient);
|
|
---Purpose : Gets a list of entities and adds its to the iteration list
|
|
|
|
AddItem (me : in out; anentity : any Transient);
|
|
---Purpose : Adds to the iteration list a defined entity
|
|
|
|
GetOneItem (me : in out; anentity : any Transient) is static;
|
|
---Purpose : same as AddItem (kept for compatibility)
|
|
|
|
Reset (me : in out) is protected;
|
|
---Purpose : Allows subclasses of EntityIterator to reevaluate an iteration
|
|
|
|
SelectType (me : in out; atype : Type; keep : Boolean);
|
|
---Purpose : Selects entities with are Kind of a given type, keep only
|
|
-- them (is keep is True) or reject only them (if keep is False)
|
|
|
|
|
|
NbEntities (me) returns Integer is static;
|
|
---Purpose : Returns count of entities which will be iterated on
|
|
-- Calls Start if not yet done
|
|
|
|
NbTyped (me; type : Type) returns Integer is static;
|
|
---Purpose : Returns count of entities of a given type (kind of)
|
|
|
|
Typed (me; type : Type) returns EntityIterator;
|
|
---Purpose : Returns the list of entities of a given type (kind of)
|
|
|
|
Start (me) is virtual;
|
|
---Purpose : Allows re-iteration (useless for the first iteration)
|
|
|
|
More (me) returns Boolean;
|
|
---Purpose : Says if there are other entities (vertices) to iterate
|
|
-- the first time, calls Start
|
|
|
|
Next (me) raises NoMoreObject;
|
|
---Purpose : Sets iteration to the next entity (vertex) to give
|
|
|
|
Value (me) returns any Transient raises NoSuchObject;
|
|
---Purpose : Returns the current Entity iterated, to be used by Interface
|
|
-- tools or by GraphTools (where Entity is a Vertex)
|
|
---C++ : return const &
|
|
|
|
Content (me) returns HSequenceOfTransient;
|
|
---Purpose : 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
|
|
|
|
Destroy (me : in out) is virtual;
|
|
---Purpose : Clears data of iteration
|
|
---C++: alias "Standard_EXPORT virtual ~Interface_EntityIterator() { Destroy();}"
