• Interface Summary 

  Interface	Description
  Channel	Channel interface A channel is a representation of a group of nodes all participating in some sort of communication with each other.
  ChannelInterceptor	A ChannelInterceptor is an interceptor that intercepts messages and membership messages in the channel stack.
  ChannelInterceptor.InterceptorEvent
  ChannelListener	Title: ChannelListener Description: An interface to listens to incoming messages from a channel When a message is received, the Channel will invoke the channel listener in a conditional sequence.
  ChannelMessage	Message that is passed through the interceptor stack after the data serialized in the Channel object and then passed down to the interceptor and eventually down to the ChannelSender component
  ChannelReceiver	ChannelReceiver Interface The ChannelReceiver interface is the data receiver component at the bottom layer, the IO layer (for layers see the javadoc for the Channel interface).
  ChannelSender	ChannelReceiver Interface The ChannelSender interface is the data sender component at the bottom layer, the IO layer (for layers see the javadoc for the Channel interface).
  ErrorHandler	The ErrorHandler class is used when sending messages that are sent asynchronously and the application still needs to get confirmation when the message was sent successfully or when a message errored out.
  Heartbeat	Can be implemented by the ChannelListener and Membership listeners to receive heartbeat notifications from the Channel
  ManagedChannel	Channel interface A managed channel interface gives you access to the components of the channels such as senders, receivers, interceptors etc for configurations purposes
  Member	The Member interface, defines a member in the group.
  MembershipListener	The MembershipListener interface is used as a callback to the membership service.
  MembershipService	MembershipService Interface The MembershipService interface is the membership component at the bottom layer, the IO layer (for layers see the javadoc for the Channel interface).
  MessageListener	Title: MessageListener Description: The listener to be registered with the ChannelReceiver, internal Tribes component

• Class Summary 

  Class	Description
  ByteMessage	A byte message is not serialized and deserialized by the channel instead it is sent as a byte array By default Tribes uses java serialization when it receives an object to be sent over the wire.
  ChannelException.FaultyMember	Title: FaultyMember class Description: Represent a failure to a specific member when a message was sent to more than one member
  UniqueId	Title: Represents a globally unique Id Company:

• Exception Summary 

  Exception	Description
  ChannelException	Channel Exception A channel exception is thrown when an internal error happens somewhere in the channel.
  RemoteProcessException	Title: RemoteProcessException Description: Message thrown by a sender when USE_SYNC_ACK receives a FAIL_ACK_COMMAND.
