MEvaluationManager Class Reference

#include <MEvaluationManager.h>

Class Description

Class for working with Maya's Evaluation Manager.

The Evaluation Manager is used to evaluate the scene without dirty propagation. Its evaluation graph capabilities decouples the data model and evaluation.

The Evaluation Manager can execute graph evaluation in serial or parallel. Parallel execution uses a scheduling graph to provide parallelized computation of depend nodes.

Unless specified, the methods in this class are threadsafe and can be performed safely from worker threads.

Member Function Documentation

bool graphConstructionActive ( )

static

Determine if the evaluation graph is currently being constructed.

Note

This function doesn't take context as a parameter because dirty propagation happens only in normal context.

Returns

True if the evaluation graph is being constructed, otherwise false.

Examples:

bool evaluationManagerActive ( const MDGContext &  context )

static

Determine if the evaluation manager is active on given context.

Parameters

[in]

context

Evaluation context for status test.

Returns

True if the evaluation manager is active on the given context, otherwise false.

Examples:

bool evaluationInExecution ( const MDGContext &  context )

static

Determine if the evaluation manager is currently evaluating given context.

Parameters

[in]

context

Evaluation context for status test.

Returns

True if the evaluation manager is evaluating given context, otherwise false.

const char * className ( )

static

Returns the name of this class.

Returns

The name of this class.
