Constructor Summary

Node(Node parent, java.lang.String name)
This creates a new blend node.

Method Summary

void	addChild(Node child) This method adds a child to the node's child list
protected int	getChildIndex(Node whichChildAmI)
java.lang.String	getName() This method returns this node's unique name.
CompareNode	getStartingCompareNode() This returns the first compare node.
abstract java.lang.String	whereDoIGoOnFail(Node whichChildAmI)
abstract java.lang.String	whereDoIGoOnPass(Node whichChildAmI) When a child node finishes its processing it can either have passed or failed and needs a destination to jump to (another compare-node or the pass/fail blocks).
