The return value indicates whether the message was finally processed (true), or not (false). The message handler is used in target, where it is either registered for a message ID, or where it serves as a null handler as a handler for all unspecified messages. https://sillysky.net/docs/nyssr/namespaces/targets/ctarget/imessagehandlerregistry/ Tue, 14 Oct 2025 00:00:00 +0000 https://sillysky.net/docs/nyssr/namespaces/targets/ctarget/imessagehandlerregistry/ This registry holds a map for message handler to process messages. Accordingly, there are methods for adding handlers void addMessageHandler(@Nullable IId aMID, @NotNull IMessageHandler aHandler); or to remove handlers: void removeMessageHandler(@NotNull IId aMID); void removeMessageHandler(@NotNull IId aMID, @NotNull IMessageHandler aHandler); The key for the map is a message ID. A special case is the message ID null, since this message handler receives all messages for which no message handlers have been installed.
