|
|
// CLASS DESCRIPTION (MItDependencyNodes)
|
|
//
|
|
// Use the dependency node iterator to traverse all the nodes in Maya's
|
|
// Dependency Graph.
|
|
//
|
|
// With filtering enabled, the iterator checks to see if the node is
|
|
// compatible with the type specified by the filter. See MFn::Type for a
|
|
// list of all valid types.
|
|
//
|
|
// Since MObjects may be compatible with more than one type (nodes are
|
|
// organised in a hierarchy) the MObject::hasFn() method can be used to
|
|
// further check for compatible types.
|
|
//
|
|
// Any compatible Function Set can be attached to the retrieved object to
|
|
// query or or edit it. Often you will want to use the dependency node
|
|
// function set (MFnDependencyNode), which is compatible with all
|
|
// dependency nodes, to perform queries on each node as the iterator
|
|
// Traverses the Dependency Graph.
|
