Detailed 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.

Member Enumeration Documentation

Specify which type of published node.

Enumerator
kParentAnchor 

published as parent anchor

kChildAnchor 

published as child anchor

kGeneric 

published as node (non-anchor)

Constructor & Destructor Documentation

MFnContainerNode ( MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe return status
Status Codes:
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
MFnContainerNode ( const MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe return status
Status Codes:
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MStatus makeCurrent ( bool  isCurrent = true)

Set or clear whether the container managed by this function set is denoted as the the current container.

If the flag is true and the container is allowed to be current, then the current container is set to be the container. Otherwise, if the container managed by the function set is the current container, then the current container is cleared.

Parameters
[in]isCurrentSpecifies whether this container shall be current
Returns
