IO Component to receive messages over some network transport
org.apache.catalina.tribes.ChannelSender
IO Component to send messages over some network transport
org.apache.catalina.tribes.MembershipService
IO Component that handles membership discovery and
org.apache.catalina.tribes.ChannelInterceptor
interceptors between the Channel and the IO layer

The message that is sent through the interceptor stack down to the IO layer
org.apache.catalina.tribes.Member
Identifies a node, implementation specific to the underlying IO logic
See: Description
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 | 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
|
Constants | Deprecated
Unused - will be removed in 8.0.x
|
UniqueId |
Title: Represents a globally unique Id
Company:
|
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.
