Interface Message

All Known Implementing Classes:

MessageImpl

public interface Message

Used to wrap an application message that is being sent from one egg to another.

The Message instance not wraps the sending egg's concrete message object, but also holds a reference to the sending egg's own message port and the priority of the message.

An egg can use a EggContext.createMessage(), to wrap an application message before writing it to a message port. This can save unnecessary object creation when the same message will be sent to a list of ports.

Method Summary

Port	getFrom() Return the port of the egg that sent this message.
java.lang.Object	getMessage() Return the application message.
Priority	getPriority() Return the dispatch priority of this message.
