Class Base64OutputStream

java.lang.Object
  java.io.OutputStream
      java.io.FilterOutputStream
          com.compoze.util.Base64OutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class Base64OutputStream
extends java.io.FilterOutputStream

This class provides an implementation of a Base 64 encoder in the form of an extension of FilterOutputStream. It is based on the implementation of BASE64EncoderStream from Sun's JDK utility classes.
