Class FlattenedTreeNodeImpl

  • All Implemented Interfaces:
    FlattenedTreeNode, GenericTreeNode
    public class FlattenedTreeNodeImpl
extends java.lang.Object
implements FlattenedTreeNode
    This is the implementation class for the FlattenedTreeNode interface. In general, this class delegates to a held GenericTreeNode with the exception of the "parent" link. When a root node is being traversed, it may not be the root node in its containing graph. Instead of requiring the node to be a root in the larger tree, we simply manage the parent link in this object.
    Since:
    MicroStrategy Web 9.0.0
