Method Detail

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.

join

public int join()
         throws InterruptedException,
                IOException

Waits for the completion of the process.

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

kill

public void kill()
          throws InterruptedException,
                 IOException

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
