Class ReplaceInputStream

java.lang.Object
  java.io.InputStream
      org.jscience.io.InterceptInputStream
          org.jscience.io.ReplaceInputStream

All Implemented Interfaces:

java.io.Closeable, InterceptInputStream.Handler

public class ReplaceInputStream
extends InterceptInputStream
implements InterceptInputStream.Handler

This specialized stream replaces all occurences of a given byte pattern with another throughout the stream. Also, this class can easily be overwritten to e.g. only replace only the first or every second occurrence or the alike.
