Class OutgoingBufferPool

java.lang.Object

org.jgroups.util.OutgoingBufferPool

public class OutgoingBufferPool
extends java.lang.Object

Maintains a pool of ExposedDataOutputStreams. The main reason is that a ByteArrayOutputStream starts with 1024 bytes, and almost always increases to 65K (max size of a UDP datagram). We save a few copies when the BAOS increases its size by pooling those.
