示例1: SetNodeID

// make sure we have the dynamic attribute to store our id created
MObject attr = nodeFn.attribute(MString (s_TUIDAttributeName), &status);
if (status == MS::kFailure)
{
// check to see if we are a locked node
bool nodeWasLocked = nodeFn.isLocked();

// turn off any node locking so an attribute can be added
nodeFn.setLocked( false );
}
// create the attribute

// reset to the prior state of wasLocked
if ( nodeWasLocked )

}
// error check
