Examples of com.sun.messaging.jmq.io.Packet

com.sun.messaging.jmq.io.Packet
Encapsulation of an iMQ packet. A packet consists of three parts: 1) A fixed sized header (size HEADER_SIZE bytes) 2) A variable sized header (for holding strings, and optional packet fields) 3) A serialized java.util.Hashtable (for holding message properties) 4) the packet body (a bag of bytes) This class directly manages #1, uses PacketVariableHeader to manage #2, and uses PacketPayload to manage #3 and #4. This class also employs the use of a buffer pool to manager reuse of direct ByteBuffers. Direct ByteBuffers are an order of magnitude more expensive to allocate than normal ByteBuffers, so keeping a pool of them around is a big win (which is not typically the case for memory allocated off of the Java heap).
