Operations

RInt poll() throws ServerError

Returns the return code of the process, or null if unfinished.

int wait() throws ServerError

bool cancel() throws ServerError

Signal to the Process that it should terminate. This may be done "softly" for a given time period.

bool kill()

Terminate the Process immediately.

void shutdown()

void unregisterCallback(ProcessCallback* cb) throws ServerError

Remove a callback for end-of-life events
