Class Description

container function set

MFnContainerNode is the function set for creating, querying and editing containers.

Maya uses container nodes to bundle sets of related nodes together with a published attribute list that defines the primary interface to those nodes. This class allows you to query information about container nodes in the Maya scene.

Examples:: sceneAssembly/assemblyReference.cpp.
