Method Detail

wantWrite

void wantWrite()

Invoke this to indicate you wish to write to the launched process's stdin.

Your ListeningProcessExecutor.ProcessListener.onStdinReady(ByteBuffer) method will be invoked asynchronously when the process is ready to receive data on stdin.

writeStdin

void writeStdin(ByteBuffer buffer)

Invoke this to directly write data to the launched process's stdin. This method does not block, and will enqueue the buffer to be written to the launched process's stdin at a later date.

If you need to be notified when the write to stdin completes, use wantWrite() and ListeningProcessExecutor.ProcessListener.onStdinReady(ByteBuffer) instead.

closeStdin

void closeStdin(boolean force)

Closes the stdin of the process. Call this if the process expects stdin to be closed before it writes to stdout.

If force is true, then pending writes to stdin are discarded. Otherwise, waits for pending writes to flush, then closes stdin.

hasPendingWrites

boolean hasPendingWrites()

Returns true if the process has any data queued to write to stdin, false otherwise.

isRunning

boolean isRunning()

Returns true if the process is running, false otherwise.
