Class StreamByteBuffer

java.lang.Object
  org.codehaus.groovy.grails.web.util.StreamByteBuffer

public class StreamByteBuffer
extends java.lang.Object

An in-memory buffer that provides OutputStream and InputStream interfaces. This is more efficient than using ByteArrayOutputStream/ByteArrayInputStream This is not thread-safe, it is intended to be used by a single Thread.
