Class OutputStreamProxy

java.lang.Object
  java.io.OutputStream
      org.entityfs.support.io.OutputStreamProxy

All Implemented Interfaces:

Closeable, Flushable

Direct Known Subclasses:

Base64OutputStream, CountingOutputStream, LockAwareOutputStream

public abstract class OutputStreamProxy
extends OutputStream

This is an abstract proxy implementation for wrapping an OutputStream in a proxy object. The orthodox way to do the same would be to let the wrapping class inherit FilterOutputStream, but that turned out to be a real performance hog.

Subclasses inherit this class and override methods as needed.

This would really be easier if OutputStream had been an interface...
