Method Detail

watchProcess

public static int watchProcess(Process process)
                        throws InterruptedException

Deprecated.

Watches a running process. This method will wait until the process as finished executing before returning with its exit value. It ensures the process does not hang on some platform by making use of the StreamGobbler to read its error and output stream.

Parameters:

process - the process to watch

Returns:

process exit value

Throws:

InterruptedException - problem while waiting for process to finish

watchProcess

public static int watchProcess(Process process,
                               com.norconex.commons.lang.io.IStreamListener listener)
                        throws InterruptedException

Deprecated.

Watches a running process. This method will wait until the process as finished executing before returning with its exit value. It ensures the process does not hang on some platform by making use of the StreamGobbler to read its error and output stream. The listener will be notified every time an error or output line gets written by the process. The listener line type will either be "STDERR" or "STDOUT".

Parameters:

process - the process to watch

listener - the listener to use for both "STDERR" or "STDOUT".

Returns:

process exit value

Throws:

InterruptedException - problem while waiting for process to finish

watchProcess

public static int watchProcess(Process process,
                               com.norconex.commons.lang.io.IStreamListener[] listeners)
                        throws InterruptedException

Deprecated.

Watches a running process. This method will wait until the process as finished executing before returning with its exit value. It ensures the process does not hang on some platform by making use of the StreamGobbler to read its error and output stream. The listener will be notified every time an error or output line gets written by the process. The listener line type will either be "STDERR" or "STDOUT".

Parameters:

process - the process to watch

listeners - the listeners to use for both "STDERR" or "STDOUT".

Returns:

process exit value

Throws:

InterruptedException - problem while waiting for process to finish

watchProcess

public static int watchProcess(Process process,
                               com.norconex.commons.lang.io.IStreamListener outputListener,
                               com.norconex.commons.lang.io.IStreamListener errorListener)
                        throws InterruptedException

Deprecated.

watchProcess

public static int watchProcess(Process process,
                               com.norconex.commons.lang.io.IStreamListener[] outputListeners,
                               com.norconex.commons.lang.io.IStreamListener[] errorListeners)
                        throws InterruptedException

Deprecated.

It ensures the process does not hang on some platform by making use of the StreamGobbler to read its error and output stream. The listeners will be notified every time an error or output line gets written by the process. The listener line type will either be "STDERR" or "STDOUT".

Parameters:

process - the process to watch

outputListeners - the process output listeners

errorListeners - the process error listeners

Returns:

process exit value

Throws:

InterruptedException - problem while waiting for process to finish

watchProcessOutput

public static void watchProcessOutput(Process process,
                                      com.norconex.commons.lang.io.IStreamListener outputListener,
                                      com.norconex.commons.lang.io.IStreamListener errorListener)

Deprecated.

Watches process output. This method is the same as watchProcess(Process, IStreamListener, IStreamListener) with the exception of not waiting for the process to complete before returning.

Parameters:

process - the process on which to watch outputs

outputListener - the process output listeners

errorListener - the process error listeners

Since:

2.0

watchProcessOutput

public static void watchProcessOutput(Process process,
                                      com.norconex.commons.lang.io.IStreamListener[] outputListeners,
                                      com.norconex.commons.lang.io.IStreamListener[] errorListeners)

Deprecated.

Watches process output. This method is the same as watchProcess(Process, IStreamListener[], IStreamListener[]) with the exception of not waiting for the process to complete before returning.

Parameters:

process - the process on which to watch outputs

outputListeners - the process output listeners

errorListeners - the process error listeners

Since:
