Class Buffer

java.lang.Object
  org.mobicents.media.Buffer

All Implemented Interfaces:

java.io.Serializable

public class Buffer
extends java.lang.Object
implements java.io.Serializable

Standard JMF class -- see this class in the JMF Javadoc. Coding complete. An observation on the use of Buffer in JMF: it appears that a Buffer is not considered to be immutable as it is processed (by a Codec, etc). JMF will do things like swap the data of two Buffers, or when input is not consumed, update the offset and length. The result of this is that care needs to be taken in implementation code to clone buffers if a buffer is to be used for multiple things (like in a cloned DataSource).
