Class DebugReader

java.lang.Object
  java.io.Reader
      dd.util.DebugReader

public class DebugReader

extends java.io.Reader

A utility for debugging reading. A DebugReader is merely a wrapper for another reader. It intercepts the calls to that reader and prints the results on standard output. This is a useful "filter" to determine what methods in the Reader are actually being called by a user of the reader.
