Interface MessageDeserializer

All Known Implementing Classes:

ConsistentJoinProtocol.CJPDeserializer, GCPastImpl.GCPastDeserializer, JavaSerializedDeserializer, JavaSerializedDeserializer, PastImpl.PastDeserializer, PeriodicLeafSetProtocol.PLSPMessageDeserializer, PJavaSerializedDeserializer, StandardJoinProtocol.SJPDeserializer

public interface MessageDeserializer

Because Pastry/Transport layer cannot know about all messge types, each app needs to provide a deserializer. Default, there is a Java Serializer

Method Summary

Message

deserialize(InputBuffer buf, short type, int priority, NodeHandle sender) Typical implementation: RawMessage ret = super.deserialize(); if (ret != null) return ret; Endpoint endpoint; switch(type) { case 1: return new MyMessage(buf, endpoint); }
