myProcessState

public ProcessState myProcessState

Current state of this process

listeners

protected final List<ISimProcessListener> listeners

A list of process listeners getting notifications on resume and suspend

processStrategy

public final ISimProcessStrategy processStrategy

Strategy used to suspend threads if requested

Constructor Detail

SimulatedProcess

public SimulatedProcess(ISimProcessStrategy processStrategy)

Default constructor.

Parameters:

processStrategy -

Method Detail

startProcess

public void startProcess(ISimProcessStrategy processStrategy)

actions

public void actions()

isTerminated

public boolean isTerminated()

Description copied from interface: ISimProcess

Returns whether this process has finished its execution.

Specified by:

isTerminated in interface ISimProcess

passivate

public void passivate()

Description copied from interface: ISimProcess

Passivates this process. This will suspend the simulation of the process until it is resumed again using the scheduleAt method.

Specified by:

passivate in interface ISimProcess

getAbstractProcess

protected abstract AbstractSimProcessDelegator getAbstractProcess()

suspend

public void suspend()

resume

protected void resume()

addProcessListener

public void addProcessListener(ISimProcessListener l)

Specified by:

addProcessListener in interface ISimProcess

removeProcessListener

public void removeProcessListener(ISimProcessListener l)

Specified by:

removeProcessListener in interface ISimProcess

notifyListeners

protected void notifyListeners(ISimProcess process,
                               ProcessState oldState,
                               ProcessState newState)

Notifies registered listeners that the given process is about to be suspended or resumed again.

Parameters:

process - the process which is being resumed or suspended

isSuspending - true, if the process is about to be suspended; false, if the process is about to be resumed

preempt

public void preempt()

Specified by:

preempt in interface ISimProcess
