◆ getExitCode()

int denoptim.task.ProcessHandler.getExitCode ( )

Get the exit code returned by the sub-process.

Returns: the value of the exit code returned by the sub-process. A negative value indicates the process was never launched or never returned.

◆ getStandardOutput()

String denoptim.task.ProcessHandler.getStandardOutput ( )

Get the content of the standard output for the process.

Returns: the output as a string.

◆ runProcess()

void denoptim.task.ProcessHandler.runProcess ( ) throws DENOPTIMException

Run the process associated with the command.

http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=4 For any Process, the input and error streams must read even if the data written to these streams is not used by the application. The generally accepted solution for this problem is a stream gobbler thread that does nothing but consume data from an input stream until stopped.
