Method Detail

run

public void run()

Description copied from class: Agent

To be implemented by the agent. This is the main method of the Agent. This method is called by AgentScape as soon as the agent starts.

Once this function finishes, the agent is done. This can be preceded by a successful call to move(AgentScapeID) if the agent should continue to run on another location. If no successful move was done beforehand, then the agent is removed from the location.

Note that it is assumed that, once an agent moved to another location, this method will finish soon afterwards. There is no protection against this (yet) however.

Any cleanup operations can be done by implementing Agent.cleanUp().

cleanUp

protected void cleanUp()

Description copied from class: Agent

User definable cleanup of the agent before stopping. This method is called by the method Agent.stopRunning(), which is called by AgentScape whenever the agent moves or is (being) killed. An Agent-developer can override this method to perform any cleanup necessary before the agent is stopped permanently, such as stopping any threads this agent has created or removing any windows that have been put on the screen.

This method may not throw any Exceptions.
