Constructor Detail

ProcessUtilImpl.ProcessExecutor

public ProcessUtilImpl.ProcessExecutor(ProcessContext context,
                                       ProcessBuilder[] builders)
                                throws IOException

The constructor.

Parameters:

context - is the context of the process pipe.

builders - are the configurations of the Process(es) to execute. The array needs to have a length greater than zero.

Throws:

IOException - if an input/output error occurred.

Method Detail

dispose

protected void dispose()

This method disposes this executor. All processes are destroyed and all streams are closed.

stop

public void stop()

This method stops the task.

Specified by:

stop in interface Stoppable

call

public Integer call()
             throws InterruptedException

This method executes the Process(es).

Specified by:

call in interface Callable<Integer>

Returns:

the return-code of the (last) process.

Throws:

InterruptedException - if a process was interrupted.
