Description copied from interface: OutputListener

nBytes new output bytes are in buffer to analyse

Specified by:

analyseBytes in interface OutputListener

charset - character set assumed by the logic engine

streamEnded

public void streamEnded(String originStd)

Assume there are no network problems, hence unexpected stream end means Prolog process has died unexpectedly

Specified by:

streamEnded in interface OutputListener

addRecognizerListener

public void addRecognizerListener(RecognizerListener l)

removeRecognizerListener

public void removeRecognizerListener(RecognizerListener l)

toString

public String toString()

Overrides:

toString in class Object
