Interface TreeNode

All Superinterfaces:
java.lang.Cloneable, java.lang.Comparable, java.io.Serializable

public interface TreeNode
extends java.lang.Cloneable, java.io.Serializable, java.lang.Comparable

This interface defines a tree node for trace-out. The nodes of the tree can either be network nodes or virtual nodes on network links.


Method Summary

 TreeNode[] getChildNodeArray()
          Returns the child tree node in an array
 double getCost()
          Returns the cost from root node
 int getDepth()
          Returns the depth of the node form root.
 double getDuration()
          Returns the sum of duration from root to this tree node
 JGeometry getGeometry()
          Returns the geometry of the tree node
 Link getLink()
          Returns the link and percentage on the link if the tree node is a node on the link isNodeOnLink() == true
 Node getNode()
          If the node is a regular node (not a node on a link)
 TreeNode getParentNode()
          Returns the parent tree node
 double getPercentage()

 TreeLink getTreeLink()
          Returns the tree link that leads to this tree node
 boolean isLeafNode()
          Returns the tree link array that leads to the child nodes i-th tree link leads to i-th child tree node public TreeLink getTreeLink() ; /** Is the node a leaf node?
 boolean isNodeOnLink()
          Check whether this node is on a link.
 boolean isRegularNode()
          Returns the regular node if the tree node is a regular node isNodeOnLink() == false

Method Detail

getParentNode

TreeNode getParentNode()
Returns the parent tree node

getChildNodeArray

TreeNode[] getChildNodeArray()
Returns the child tree node in an array

isLeafNode

boolean isLeafNode()
Returns the tree link array that leads to the child nodes i-th tree link leads to i-th child tree node public TreeLink getTreeLink() ; /** Is the node a leaf node?

isNodeOnLink

boolean isNodeOnLink()
Check whether this node is on a link. A tree node can either be a regular node or a node on a link

isRegularNode

boolean isRegularNode()
Returns the regular node if the tree node is a regular node isNodeOnLink() == false

getNode

Node getNode()
If the node is a regular node (not a node on a link)

getLink

Link getLink()
Returns the link and percentage on the link if the tree node is a node on the link isNodeOnLink() == true

getPercentage

double getPercentage()
Returns the link and percentage on the link if the tree node is a node on the link isNodeOnLink() == true

addChildNode

void addChildNode(TreeLink tLink,
                  TreeNode tNode)
Adds a child tree node to current tree node

getDepth

int getDepth()
Returns the depth of the node form root. Root has depth 0

getCost

double getCost()
Returns the cost from root node

getTreeLink

TreeLink getTreeLink()
Returns the tree link that leads to this tree node

getGeometry

JGeometry getGeometry()
Returns the geometry of the tree node

getDuration

double getDuration()
Returns the sum of duration from root to this tree node
Returns:
sum of duration
