trueif the node is of a type which can have child nodes,falseotherwise
-
getChildIterator
public java.util.Iterator getChildIterator()
Description copied from class:DefaultDataNodeThe DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren()is false).- Specified by:
