Constructor Detail

OutputStreamConnector

protected OutputStreamConnector(WindowsSession session,
                                OutputStream stdOut,
                                OutputStream stdErr)

Create an OutputStreamConnector to link the output streams of the remote process controlled by the WindowsSession.

Parameters:

session - the WindowsSession running the remote process

stdOut - the OutputStream to write the process stdout stream to

stdErr - the OutputStream to write the process stderr stream to

Method Detail

getOutputStream

public OutputStream getOutputStream()

Obtain the OutputStream this connector pipes the remote process stdout to.

Returns:

the OutputStream this connector pipes the remote process stdout to

getErrorStream

public OutputStream getErrorStream()

Obtain the OutputStream this connector pipes the remote process stderr to.

Returns:

the OutputStream this connector pipes the remote process stderr to

getSession

public WindowsSession getSession()

Obtain the WindowsSession running the remote process.

Returns:

the WindowsSession running the remote process

close

public void close()

Closes this OutputStreamConnector and stops the run loop.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

waitFor

public Integer waitFor(com.oracle.bedrock.Option... options)

Causes the current thread to wait, if necessary, until the remote command has terminated.

Parameters:

options - the Options for waiting, including Timeout

Returns:

the exit code of the remote command. By convention, the value 0 indicates normal termination

Throws:

RuntimeException - if there was a problem waiting for termination

getExitCode

public int getExitCode()

Obtain the exit value of the remote process or -1 if the process has not yet terminated.

Returns:

the exit value of the remote process or -1 if the process has not yet terminated

pollOutput

public boolean pollOutput()
                   throws IOException

Poll for the current process output from the remote command.

Returns:

true if the process is still running otherwise false.

Throws:

IOException - if an error occurs.

run

public void run()

The run loop for this Thread.
