Examples of MessageStream

com.caucho.bam.stream.MessageStream
Primary stream handling all message packets. {@link com.caucho.bam.actor.ActorHolder Actors} send packets to the {@link com.caucho.bam.broker.Broker} for delivery to other Actors.Messages are divided into two groups:
- message - unidirectional messages
- query - RPC call/reply packets
groovyx.gpars.actor.impl.MessageStream
Represents a stream of messages and forms the base class for actors @author Alex Tkachman, Vaclav Pech, Dierk Koenig
org.apache.james.util.stream.MessageStream
Helper class to write to temporary file for transfer data. This is mostly useful for writing large chunk of data back the the client. This Object is designed for one time use..
