DefaultProcessMonitor(java.io.Writer writer)

Method Summary

void	executionFailed(ExecutionException e) Called when the execution fails due to an execption.

void	executionFinished(Process process, ValueMap inputs, ValueMap outputs) Called after the execution of a process finishes.
void	executionStarted() Called only once when the execution of the top-most process starts
void	executionStarted(Process process, ValueMap inputs) Called before the execution of a process starts.
int	getMonitorFilter()
void	setMonitorFilter(int processType) Control if executionStarted and executionFinished will be called for all the processes or only for a specific type of processes.

executionStarted

public void executionStarted()

Description copied from interface: ProcessMonitor

Called only once when the execution of the top-most process starts

Specified by:

executionStarted in interface ProcessMonitor

executionFinished

public void executionFinished()

Description copied from interface: ProcessMonitor

Called only once when the execution of the top-most process finishes. Note that if execution fails for any reason this function will not be called. Instead executionFailed() will be called.

Specified by:

executionFinished in interface ProcessMonitor

executionStarted

public void executionStarted(Process process,
                             ValueMap inputs)

Description copied from interface: ProcessMonitor

Called before the execution of a process starts. The user has the option to modify the contents of the inputs. setMonitorFilter function can be used to control if this function will be called for all the processes or only for a specific type of processes (e.g. only atomic processes).

Specified by:

executionStarted in interface ProcessMonitor

executionFinished

public void executionFinished(Process process,
                              ValueMap inputs,
                              ValueMap outputs)

Description copied from interface: ProcessMonitor

Called after the execution of a process finishes. The user has the option to modify the contents of outputs. setMonitorFilter function can be used to control if this function will be called for all the processes or only for a specific type of processes (e.g. only atomic processes).

Specified by:

executionFinished in interface ProcessMonitor

executionFailed

public void executionFailed(ExecutionException e)

Description copied from interface: ProcessMonitor

Called when the execution fails due to an execption. This function is intended to be hook where the user can do something to fix the problem, i.e. ask for additional inputs. There is no such support at the moment. The execution engine will throw the exception right after this function returns.

Specified by:

executionFailed in interface ProcessMonitor

setMonitorFilter

public void setMonitorFilter(int processType)

Description copied from interface: ProcessMonitor

Control if executionStarted and executionFinished will be called for all the processes or only for a specific type of processes. The constant values are defined in Process interface:

• Process.ANY
• Process.ATOMIC
• Process.COMPOSITE
• Process.SIMPLE

Bitwise combinations (bitwise or) of these values are also valid.

Specified by:

setMonitorFilter in interface ProcessMonitor

getMonitorFilter

public int getMonitorFilter()

Specified by:

getMonitorFilter in interface ProcessMonitor
