Class ThresholdOutputStream

java.lang.Object
  java.io.OutputStream
      org.apache.chemistry.opencmis.server.shared.ThresholdOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class ThresholdOutputStream
extends java.io.OutputStream

An OutputStream that stores the data in main memory until it reaches a threshold. If the threshold is passed the data is written to a temporary file. It it is important to close this OutputStream before getInputStream() is called or call destroy() if the InputStream isn't required!

Nested Class Summary

static interface

ThresholdOutputStream.ThresholdInputStream Provides information about the input stream.

Constructor Summary
