Class GraphNode

java.lang.Object
  |
  +--utilities.GraphNode

All Implemented Interfaces:

java.lang.Cloneable, java.lang.Comparable, ConfiguredObject, java.io.Serializable

Direct Known Subclasses:

ContainerGraphNode, GraphEdge

public class GraphNode

extends java.lang.Object

implements java.io.Serializable, java.lang.Cloneable, ConfiguredObject, java.lang.Comparable

This is a superclass for the generic purpose of drawing graphs made up of nodes and edges. Its primary purpose is for the resource hierarchy interface.

It should probably not be instantiated directly. It is modeled after taems' Node class, minus the agent/tames specific stuff.

GraphNode

public GraphNode(java.lang.String l)

Default constructor

Parameters:

l - The node's label

GraphNode

public GraphNode()

Blank Constructor

Method Detail

updateCfg

public void updateCfg()

Description copied from interface: ConfiguredObject

updates the information in this object with information currently in the CfgManager.

Specified by:

updateCfg in interface ConfiguredObject

saveCfg

public void saveCfg()

Description copied from interface: ConfiguredObject

saves the information in this object to the proper location in the CfgManager.

Specified by:

saveCfg in interface ConfiguredObject

getLabel

public java.lang.String getLabel()

Accessors

setLabel

public void setLabel(java.lang.String l)

getAttribute

public java.lang.Object getAttribute(java.lang.Object k)

Note that this uses the toString() method for the key to actually store the object.

Parameters:

k - The key identifying the desired attribute

Returns:

The object, or null if not found

setAttribute

public void setAttribute(java.lang.Object k,
                         java.lang.Object d)

Sets an attribute's data. Attribute keys should not contain whitespace.

If a key is added with a null data object, the key will be removed from the attribute set.

Parameters:

k - The key identifying the desired attribute

d - The attribute data

getAttributes

public java.util.Enumeration getAttributes()

Returns the attribute names

Returns:

An enumeration of all the attribute keys

hasAttribute

public boolean hasAttribute(java.lang.Object k)

Determines if the node has a particular attribute

Returns:

True if the attribute is present

addEdge

public void addEdge(GraphNode t)

removeEdge

public void removeEdge(GraphNode t)

addEdge

public void addEdge(GraphEdge e,
                    GraphNode t)

removeEdge
