Class ZStreamPreprocessor

java.lang.Object
  |
  +--edu.umd.cs.jazz.io.ZStreamPreprocessor

All Implemented Interfaces:

java.io.Serializable

public class ZStreamPreprocessor

extends java.lang.Object

implements java.io.Serializable

ZStreamPreprocessor preprocesses the java io stream to manage embedded binary data.

Warning: Serialized and ZSerialized objects of this class will not be compatible with future Jazz releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Jazz. A future release of Jazz will provide support for long term persistence.
