MEvaluationNode

If you need to access the list of dirty plugs in an MEvaluationNode node then use the internal iterator:

MEvaluationNode theNode; for( MEvaluationNodeIterator it = theNode.iterator(); !it.isDone(); it.next() ) { doSomePlugThing( it.plug() ); }

Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MEvaluationNodeIterator	(	const MEvaluationNode &	node,
		MStatus *	ReturnStatus = NULL
	)

Constructor for iterator over evaluation node's dirty plugs.

Parameters

[in]	node	Evaluation node over which to iterate
[out]	ReturnStatus	Status Code

Status Codes:

• MS::kSuccess The operation succeeded
• MS::kFailure Object error - no evaluation node

MEvaluationNodeIterator

(

const MEvaluationNodeIterator &

rhs

)

Copy constructor for iterator over evaluation node's dirty plugs.

The copied iterator is not const because it becomes empty after the copy.

Parameters

[in]

rhs

Iterator to copy

Status Codes:

• MS::kSuccess The operation succeeded
• MS::kFailure Object error - no evaluation node

Member Function Documentation

MEvaluationNodeIterator & operator=

(

MEvaluationNodeIterator &

rhs

)

Assignment operator.

The copied iterator is not const because it becomes empty after the assignment.

Parameters

[in]

rhs

Iterator from which to copy information

Returns

Reference to the assigned iterator

MPlug plug

(

)

Returns the dirty plug at the current iterator position.

Returns an empty plug if the iterator is illegal.

Returns

dirty plug at the current iterator index

bool isDone

(

)

const

Checks to see if the iterator has reached the end of the iteration.

Returns

True if the iteration has completed

const char * className ( )

static

Returns the name of this class.

Returns

Name of this class.
