Class BufferedReaderPromptInput

java.lang.Object
  org.rhq.enterprise.communications.util.prefs.BufferedReaderPromptInput

All Implemented Interfaces:

PromptInput

public class BufferedReaderPromptInput
extends Object
implements PromptInput

A simple PromptInput implementation that delegates to a buffered reader. Note that because there is no Java API that allows for reading input without echoing the typed input, this method's readLineNoEcho() really does echo (i.e. it is the same as readLine()).
