Method Detail

consumeProcessErrorStream

public Thread consumeProcessErrorStream(StringBuffer)
 
Gets the error stream from a process and reads it to keep the process from blocking due to a full buffer. The processed stream data is appended to the supplied StringBuffer. A new Thread is started, so this method will return immediately.
Parameters:
error - a StringBuffer to capture the process stderr.
Returns:
the Thread
Since:
1.5.2

consumeProcessErrorStream

public Thread consumeProcessErrorStream(OutputStream)
 
Gets the error stream from a process and reads it to keep the process from blocking due to a full buffer. The processed stream data is appended to the supplied OutputStream. A new Thread is started, so this method will return immediately.
Parameters:
err - an OutputStream to capture the process stderr.
Returns:
the Thread
Since:
1.5.2

consumeProcessErrorStream

public Thread consumeProcessErrorStream(Writer)
 
Gets the error stream from a process and reads it to keep the process from blocking due to a full buffer. The processed stream data is appended to the supplied Writer. A new Thread is started, so this method will return immediately.
Parameters:
err - a Writer to capture the process stderr.
Returns:
the Thread
Since:
1.5.2

consumeProcessOutput

public void consumeProcessOutput()
 
Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The stream data is thrown away but blocking due to a full output buffer is avoided. Use this method if you don't care about the standard or error output and just want the process to run silently - use carefully however, because since the stream data is thrown away, it might be difficult to track down when something goes wrong. For this, two Threads are started, so this method will return immediately.
Since:
1.0

consumeProcessOutput

public void consumeProcessOutput(StringBuffer, StringBuffer)
 
Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied StringBuffer. For this, two Threads are started, so this method will return immediately.
Parameters:
output - a StringBuffer to capture the process stdout.
error - a StringBuffer to capture the process stderr.
Since:
1.5.2

consumeProcessOutput

public void consumeProcessOutput(OutputStream, OutputStream)
 
Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied OutputStream. For this, two Threads are started, so this method will return immediately.
Parameters:
output - an OutputStream to capture the process stdout.
error - an OutputStream to capture the process stderr.
Since:
1.5.2

consumeProcessOutputStream

public Thread consumeProcessOutputStream(StringBuffer)
 
Gets the output stream from a process and reads it to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied StringBuffer. A new Thread is started, so this method will return immediately.

Returns:
the Thread
Since:
1.5.2

consumeProcessOutputStream

public Thread consumeProcessOutputStream(OutputStream)
 
Gets the output stream from a process and reads it to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied OutputStream. A new Thread is started, so this method will return immediately.

Returns:
the Thread
Since:
1.5.2

consumeProcessOutputStream

the error InputStream for the process
Since:
1.0

getIn

public InputStream getIn()

waitForProcessOutput

public void waitForProcessOutput()
 
Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The stream data is thrown away but blocking due to a full output buffer is avoided. Use this method if you don't care about the standard or error output and just want the process to run silently - use carefully however, because since the stream data is thrown away, it might be difficult to track down when something goes wrong. For this, two Threads are started, but join()ed, so we wait. As implied by the waitFor... name, we also wait until we finish was well.
Since:
1.6.5

waitForProcessOutput

public void waitForProcessOutput(StringBuffer, StringBuffer)
 
Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied StringBuffer. For this, two Threads are started, but join()ed, so we wait. As implied by the waitFor... name, we also wait until we finish was well.
Parameters:
output - a StringBuffer to capture the process stdout.
error - a StringBuffer to capture the process stderr.
Since:
1.6.5

waitForProcessOutput

public void waitForProcessOutput(OutputStream, OutputStream)
 
Gets the output and error streams from a process and reads them to keep the process from blocking due to a full output buffer. The processed stream data is appended to the supplied OutputStream. For this, two Threads are started, but join()ed, so we wait. As implied by the waitFor... name, we also wait until we finish was well.
Parameters:
output - an OutputStream to capture the process stdout.
error - an OutputStream to capture the process stderr.
Since:
1.6.5

withOutputStream

public void withOutputStream(Closure)
 
Creates a new buffered OutputStream as stdin for this process, passes it to the closure, and ensures the stream is flushed and closed after the closure returns. A new Thread is started, so this method will return immediately.
Parameters:
closure - a closure.
Since:
1.5.2

withWriter

public void withWriter(Closure)
 
Creates a new BufferedWriter as stdin for this process, passes it to the closure, and ensures the stream is flushed and closed after the closure returns. A new Thread is started, so this method will return immediately.
