com.phoenixst.plexus
Class SimpleEdge  

java.lang.Object
  com.phoenixst.plexus.SimpleEdge

All Implemented Interfaces:

Graph.Edge, java.io.Serializable

Direct Known Subclasses:

SimpleObjectEdge

---

public class SimpleEdge

extends java.lang.Object

implements Graph.Edge, java.io.Serializable

A simple Edge implementation which contains no user-defined object. Because of how equals( Object ) 55 is defined, instances of this class may only be used by simple graphs.

Since:

1.0

Version:

$Revision: 1.1 $

Field Summary
private  Graph	graph           The graph which created this Edge.
private  java.lang.Object	head           The head of this Edge.
private  boolean	isDirected           Whether or not this Edge is directed.
private  java.lang.Object	tail           The tail of this Edge.

 

Constructor Summary

SimpleEdge(Graph graph, java.lang.Object tail, java.lang.Object head, boolean isDirected)           Creates a new SimpleEdge.

 

Method Summary
boolean	equals(java.lang.Object object)           Two SimpleEdges are equal if they have the same directedness, are from the exact same graph (using ==), and have equal endpoints.
protected static boolean	equals(java.lang.Object a, java.lang.Object b)
boolean	equals(SimpleEdge edge)           Two SimpleEdges are equal if they have the same directedness, are from the exact same graph (using ==), and have equal endpoints.
java.lang.Object	getHead()           Returns the node which is the head of this Edge.
java.lang.Object	getOtherEndpoint(java.lang.Object node)           Returns the node which is at the other end of this Edge than the specified node.
java.lang.Object	getTail()           Returns the node which is the tail of this Edge.
java.lang.Object	getUserObject()           Returns the user object contained in this Edge.
int	hashCode()           Returns the hash code for this Edge.
boolean	isDirected()           Returns whether or not this Edge is directed.
void	setUserObject(java.lang.Object object)           Sets the user object contained in this Edge.

Field Detail

graph

private Graph graph

The graph which created this Edge.

---

tail

private java.lang.Object tail

The tail of this Edge.

---

head

private java.lang.Object head

The head of this Edge.

---

isDirected

private boolean isDirected

Whether or not this Edge is directed.

Constructor Detail

SimpleEdge

public SimpleEdge(Graph graph,
                  java.lang.Object tail,
                  java.lang.Object head,
                  boolean isDirected)

Creates a new SimpleEdge.

Method Detail

isDirected

public boolean isDirected()

Description copied from interface: Graph.Edge

Returns whether or not this Edge is directed.

Specified by:

isDirected in interface Graph.Edge

---

getUserObject

public java.lang.Object getUserObject()

Description copied from interface: Graph.Edge

Returns the user object contained in this Edge.

Specified by:

getUserObject in interface Graph.Edge

---

setUserObject

public void setUserObject(java.lang.Object object)

Description copied from interface: Graph.Edge

Sets the user object contained in this Edge.

Specified by:

setUserObject in interface Graph.Edge

---

getTail

public java.lang.Object getTail()

Description copied from interface: Graph.Edge

Returns the node which is the tail of this Edge.

Specified by:

getTail in interface Graph.Edge

---

getHead

public java.lang.Object getHead()

Description copied from interface: Graph.Edge

Returns the node which is the head of this Edge.

Specified by:

getHead in interface Graph.Edge

---

getOtherEndpoint

public java.lang.Object getOtherEndpoint(java.lang.Object node)

Description copied from interface: Graph.Edge

Returns the node which is at the other end of this Edge than the specified node.

Specified by:

getOtherEndpoint in interface Graph.Edge

---

equals

protected static final boolean equals(java.lang.Object a,
                                      java.lang.Object b)

---

equals

public boolean equals(java.lang.Object object)

Two SimpleEdges are equal if they have the same directedness, are from the exact same graph (using ==), and have equal endpoints.

Specified by:

equals in interface Graph.Edge

---

equals

public boolean equals(SimpleEdge edge)

Two SimpleEdges are equal if they have the same directedness, are from the exact same graph (using ==), and have equal endpoints.

---

hashCode

public int hashCode()

Description copied from interface: Graph.Edge

Returns the hash code for this Edge. Since it is mutable, the contained user-defined object should not be used when computing the hash code.

Description copied from class: java.lang.Object
null

Specified by:

hashCode in interface Graph.Edge

---

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()).
