Interface ReplicableCommand

    • Method Detail

      • invoke

        default Object invoke()
                       throws Throwable
        Invoke the command synchronously.

        This method is optional. Unless your command never blocks, please implement invokeAsync() instead.

      • perform

        default Object perform​(InvocationContext ctx)
                        throws Throwable
        Performs the primary function of the command. Please see specific implementation classes for details on what is performed as well as return types. Important: this method will be invoked at the end of interceptors chain. It should never be called directly from a custom interceptor.
        ctx - invocation context
        arbitrary return value generated by performing this command
        Throwable - in the event of problems.
      • getCommandId

        byte getCommandId()
        Used by marshallers to convert this command into an id for streaming.
        the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.
      • isReturnValueExpected

        boolean isReturnValueExpected()
        If true, a return value will be provided when performed remotely. Otherwise, a remote ResponseGenerator may choose to simply return null to save on marshalling costs.
        true or false
      • canBlock

        boolean canBlock()
        If true, the command is processed asynchronously in a thread provided by an Infinispan thread pool. Otherwise, the command is processed directly in the JGroups thread.

        This feature allows to avoid keep a JGroups thread busy that can originate discard of messages and retransmissions. So, the commands that can block (waiting for some state, acquiring locks, etc.) should return true.

        true if the command can block/wait, false otherwise
      • setOrigin

        default void setOrigin​(Address origin)
        Sets the sender's Address.

        By default, it doesn't set anything. Implement this method if the sender's Address is needed.

        origin - the sender's Address
