Class VirtualChain  

java.lang.Object
  com.port80.graph.dot.impl.VirtualChain

---

public class VirtualChain

extends java.lang.Object

A chain of VirtualEdge that should be routed together. Typically represents an IEdge or a portion an an IEdge (eg. a stub or a bus). The tail of a chain is the top-most VirtualVertex. The head of a chain is the bottom-most VirtualVertex.

getLength

public float getLength()

getSlack

public float getSlack()

updateLength

public float updateLength()

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

toDump

public java.lang.String toDump()

---

initLength

private VirtualVertex initLength()

Calculate chain length base on current coordinates.
