    • afterPropertiesSet

      public void afterPropertiesSet()
      Specified by:
      afterPropertiesSet in interface InitializingBean
    • addMessage

      public <T> Message<T> addMessage(Message<T> message)
      Description copied from interface: MessageStore
      Put the provided Message into the MessageStore. The store may need to mutate the message internally, and if it does then the return value can be different than the input. The id of the return value will be used as an index so that the MessageStore.getMessage(UUID) and MessageStore.removeMessage(UUID) behave properly. Since messages are immutable, putting the same message more than once is a no-op.
      Specified by:
      addMessage in interface MessageStore
      Type Parameters:
      T - The payload type.
      Parameters:
      message - The message.
      Returns:
      The message that was stored.
    • getMessage

      public Message<?> getMessage(UUID id)
      Specified by:
      getMessage in interface MessageStore
      Parameters:

      Returns:
      The Message with the given id, or null if no Message with that id exists in the MessageStore.
    • getMessageMetadata

      public MessageMetadata getMessageMetadata(UUID id)
      Description copied from interface: MessageStore
      Return a MessageMetadata for the Message by provided id.
      Specified by:
      getMessageMetadata in interface MessageStore
      Parameters:
      id - The message identifier.
      Returns:
      The MessageMetadata with the given id, or null if no Message with that id exists in the MessageStore or the message has no metadata (legacy message from an earlier version).
