Method Details

kill

public void kill()
          throws IOException,
InterruptedException

Description copied from class: Proc

Terminates the process.

Specified by:

kill in class Proc

Throws:

IOException - if there's an error killing a process and a stack trace could help the trouble-shooting.

InterruptedException

join

public int join()
         throws IOException,
InterruptedException

Description copied from class: Proc

Waits for the completion of the process. Unless the caller opts to pump the streams via Proc.getStdout() etc., this method also blocks until we finish reading everything that the process has produced to stdout/stderr.

If the thread is interrupted while waiting for the completion of the process, this method terminates the process and exits with a non-zero exit code.

Specified by:

join in class Proc

Throws:

IOException - if there's an error launching/joining a process and a stack trace could help the trouble-shooting.

InterruptedException

isAlive

public boolean isAlive()
                throws IOException,
InterruptedException

Description copied from class: Proc

Checks if the process is still alive.

Specified by:

isAlive in class Proc

Throws:

IOException

InterruptedException

getStdout

public InputStream getStdout()

Description copied from class: Proc

Returns an InputStream to read from stdout of the child process.

When this method returns null, Proc will internally pump the output from the child process to your OutputStream of choosing.

Specified by:

getStdout in class Proc

Returns:

null unless Launcher.ProcStarter.readStdout() is used to indicate that the caller intends to pump the stream by itself.

getStderr

public InputStream getStderr()

Description copied from class: Proc

Returns an InputStream to read from stderr of the child process.

When this method returns null, Proc will internally pump the output from the child process to your OutputStream of choosing.

Specified by:

getStderr in class Proc

Returns:

null unless Launcher.ProcStarter.readStderr() is used to indicate that the caller intends to pump the stream by itself.

getStdin

public OutputStream getStdin()

Description copied from class: Proc

Returns an OutputStream to write to stdin of the child process.

When this method returns null, Proc will internally pump the InputStream of your choosing to the child process.

Specified by:

getStdin in class Proc

Returns:

null unless Launcher.ProcStarter.writeStdin() is used to indicate that the caller intends to pump the stream by itself.
