All Implemented Interfaces:

Agent, Context, Resumable, Runnable, Serializable

public class JumpAgent

extends HSMAgent

This is and extended version of the JumpingAgent. The agent was designed to graphically demonstrate the migration process. It creates a frame that contains a combo box and a button. The combo box offers the user all servers that are known to the agent. If the button is pressed, the migration takes place and the agent "jumps" to the selected server.

This implementation uses a state machine.

Field Detail

commandFrame_

private transient JumpAgentGUI commandFrame_

Holds the GUI. The member is transient because GUIs can't be migrated. They aren't seralizable due to their native references to the window manager. Hence the agent will re-create its GUI on every host after migration.
