Detailed Description

Iterator of objects contained in a NIS_InteractiveContext instance. The iteration is always in the ascending sense of object ID. Examples:

*    // Erase all objects in the Context
* NIS_ObjectsIterator anIter (myContext);
* for (; anIter.More(); anIter.Next())
*   myContext->Erase (anIter.Value(), Standard_False);
*
*    // Set object attributes to their IDs (hardly useful outside the example)
* anIter.Initialize (myContext);
* Handle(NIS_InteractiveObject) anObj;
* while (!(anObj = anIter.Value().IsNull())) {
*   anObj->SetAttribute (static_cast<void *> (anObj->ID()));
*   anIter.Next();
* }
* 

Constructor & Destructor Documentation

NIS_ObjectsIterator::NIS_ObjectsIterator ( )

inline

Empty Constructor.

NIS_ObjectsIterator::NIS_ObjectsIterator ( const Handle< NIS_InteractiveContext > &  theCtx )

inline

Constructor.

Parameters

theCtx

Interactive context that is to be iterated for all objects.

Member Function Documentation

void NIS_ObjectsIterator::Initialize

(

const Handle< NIS_InteractiveContext > &

theCtx

)

Reset the Iterator to start the iterations of objects.

Parameters

theCtx

Interactive context that is to be iterated for all objects.

Standard_Boolean NIS_ObjectsIterator::More ( void  ) const

inline

Query if the Iterator has an object (not yet finished the iteration process).

void NIS_ObjectsIterator::Next

(

)

Step forward to the next valid InteractiveObject instance.

const Handle< NIS_InteractiveObject >& NIS_ObjectsIterator::Value

(

)

const

Returns the current object at the iteration pointer. If the iteration is over (More() == False) this method returns NULL Handle.
