Class BufferingOutputStream

java.lang.Object
  java.io.OutputStream
      com.bradmcevoy.io.BufferingOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class BufferingOutputStream
extends java.io.OutputStream

An output stream which will buffer data, initially using memory up to maxMemorySize, and then overflowing to a temporary file. To use this class you will write to it, and then close it, and then call getInputStream to read the data. The temporary file, if it was created, will be deleted when the inputstream is closed.
