    • handle

      public Optional<CompletableFuture<Object>> handle(DeserializingMessage message)
      Description copied from interface: HandlerRegistry
      Attempts to handle the given message using local handlers.
      Specified by:
      handle in interface HandlerRegistry
      Parameters:
      message - the deserialized message to dispatch
      Returns:
      an optional future containing the result, or empty if no handler was found

    • registerHandler

      public Registration registerHandler(Object target)
      Description copied from interface: HasLocalHandlers
      Registers the given handler object and includes only the methods that are annotated with a recognized handler annotation (e.g., @HandleCommand, @HandleQuery, etc.).

      This method uses LocalHandler to determine which methods to include. If a payload has an annotated handler like HandleQuery inside its class and the class is not annotated with TrackSelf, the handler is also considered to be local.

      Specified by:
      registerHandler in interface HasLocalHandlers
      Parameters:
      target - the object containing handler methods
      Returns:
      a Registration which can be used to unregister the handlers

    • hasLocalHandlers

      public boolean hasLocalHandlers()
      Description copied from interface: HasLocalHandlers
      Indicates whether any local handlers are currently registered for this gateway.
      Specified by:
      hasLocalHandlers in interface HasLocalHandlers
      Returns:
      true if local handlers are present, false otherwise

    • setSelfHandlerFilter

      public void setSelfHandlerFilter(HandlerFilter selfHandlerFilter)
      Description copied from interface: HasLocalHandlers
      Sets a custom filter to control whether a handler method is considered a local handler for the current application. This is typically used internally to ensure that handlers are associated with the correct application or component.
      Specified by:
      setSelfHandlerFilter in interface HasLocalHandlers
      Parameters:
      selfHandlerFilter - a HandlerFilter to apply to registered handlers

    • registerHandler

      public Registration registerHandler(Object target, HandlerFilter handlerFilter)
      Description copied from interface: HasLocalHandlers
      Registers a handler object, including only those methods that match the provided HandlerFilter.

      This method offers fine-grained control over which handler methods are registered, based on custom logic applied to method annotations and/or signatures.

      Specified by:
      registerHandler in interface HasLocalHandlers
      Parameters:
      target - the handler object containing annotated methods
      handlerFilter - the filter used to determine which methods should be registered
      Returns:
      a Registration which can be used to unregister the handlers
