Class CompressedOutputStream

java.lang.Object
  java.io.OutputStream
      java.io.FilterOutputStream
          jfreerails.util.CompressedOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class CompressedOutputStream
extends java.io.FilterOutputStream

A FilterOutputStream for sending compressed data over a network connection. Note that standard ZipOutputStream and java.util.zip.GZipOutputStream don't guarantee that flush sends out all the data written so far, which leads to deadlocks in request-response-based protocols.
