Class Message<T>

java.lang.Object

de.otto.synapse.message.Message<T>

Type Parameters:

T - The type of the Message payload

All Implemented Interfaces:

java.io.Serializable

public class Message<T>
extends java.lang.Object
implements java.io.Serializable

A Message is an atomic packet of data that can be transmitted on a channel.

Thus to transmit data, an application must break the data into one or more packets, wrap each packet as a message, and then send the message on a channel. Likewise, a receiver application receives a message and must extract the data from the message to process it.

The message system will try repeatedly to deliver the message (e.g., transmit it from the sender to the receiver) until it succeeds.
