add

public void add(ProcessListener listener)

Add new listener.

Parameters:

listener - listener to be added.

remove

public void remove(ProcessListener listener)

Remove existing listener.

Parameters:

listener - listener to be removed.

Parameters:

type - listener type.

clear

public void clear()

Remove all existing listeners.

clone

public CompositeProcessListener clone()

Overrides:

clone in class java.lang.Object

beforeStart

public void beforeStart(ProcessExecutor executor)

Description copied from class: ProcessListener

Invoked before a process is started.

Overrides:

beforeStart in class ProcessListener

Parameters:

executor - executor used for starting a process. Any changes made here apply to the starting process. Once the process has started it is not affected by the ProcessExecutor any more.

afterStart

public void afterStart(java.lang.Process process,
                       ProcessExecutor executor)

Description copied from class: ProcessListener

Invoked after a process has started.

Overrides:

afterStart in class ProcessListener

Parameters:

process - the process started.

executor - executor used for starting the process. Modifying the ProcessExecutor only affects the following processes not the one just started.

afterFinish

public void afterFinish(java.lang.Process process,
                        ProcessResult result)

Description copied from class: ProcessListener

Invoked after a process has finished successfully.

Overrides:

afterFinish in class ProcessListener

Parameters:

process - process just finished.

result - result of the finished process.

afterStop

public void afterStop(java.lang.Process process)

Description copied from class: ProcessListener

Invoked after a process has exited (whether finished or cancelled).
