Interface Summary

Interface	Description
Message	This represents internal message interface which is sent and received on the top of Shoal management module Currently, six message types exist.
MessageListener	Message listener interface For receiving and processing inbound messages, this listener should be registered on NetworkManager with corresponding to the appropriate message type i.g.
MessageSender	This interface is for sending a Message to the specific destination This interface can be implemented for only TCP or only UDP or both TCP and UDP transport layer
MulticastMessageSender	This interface is for broadcasting or multicasting a Message to all members
NetworkManager	This interface has common APIs for network managements According to a kind of transport layers, this interface will be implemented adequately.
ShoalMessageSender	This is the top interface of the message sender Currently, TCP and UDP(includes Multicast) transport layers are supported.

Class Summary

Class	Description
AbstractMessageSender	This class implements a common MessageSender logic simply in order to help the specific transport layer to be implemented easily Mainly, this stores both source's PeerID and target's PeerID before sending the message to the peer
AbstractMulticastMessageSender	This class implements a common MulticastMessageSender logic simply in order to help the specific transport layer to be implemented easily Mainly, this stores both source's PeerID and target's PeerID before broadcasting the message to all members
AbstractMultiMessageSender	This class implements both a common MulticastMessageSender and MessageSender logic simply in order to help the specific transport layer to be implemented easily Mainly, this stores both source's PeerID and target's PeerID before sending the message to the peer or broadcasting the message to all members
AbstractNetworkManager	This class implements a common NetworkManager logic simply in order to help the specific transport layer to be implemented easily Mainly, this manages MessageListener and dispatches an inbound Message into the appropriate listener
ArrayUtils	Set of utility methods to work with Arrays.
BlockingIOMulticastSender	This class is a default MulticastMessageSender's implementation and extends AbstractMulticastMessageSender This uses MulticastSocket which is based on Blocking I/O
MessageEvent	This class represents a received message event Management modules will use this message event in order to process a received network packet internally
MessageImpl	This is a default Message's implementation The byte array or ByteBuffer which represent this message's low level data will be cached if this message is not modified Here are this message's structure ---- [packet] magic(4) + version(4) + type(4) + messages_length(4) + messages(message_length) [messages] message_count(4) + message_key1 + message_value1 + message_key2 + message_value2 + ...(message_count) ----
NetworkUtility	Utility class that can be used by any calling code to do common routines about Network I/O
VirtualMulticastSender	This class extends BlockingIOMulticastSender for supporting the circumstance that cluster members are located beyond one subnet or multicast traffic is disabled virtualPeerIdList should contain PeerIDs of cluster members which are located beyond one subnet.

Exception Summary

Exception	Description
MessageIOException	IOException which related to parsing Message
