- def onAnyCommand(handler: Supplier[ReplyEffect[Event, State]]): CommandHandlerWithReply[Command, Event, State]
Matches any command.
Matches any command.
Use this to declare a command handler that will match any command. This is particular useful when encoding a finite state machine in which the final state is not supposed to handle any new command.
Use this when you just need to return an ReplyEffect without using any data from the command or from the state.
Note: command handlers are selected in the order they are added. Once a matching is found, it's selected for handling the command and no further lookup is done. Therefore you must make sure that their matching conditions don't overlap, otherwise you risk to 'shadow' part of your command handlers.
Extra care should be taken when using onAnyCommand as it will match any command. This method builds and returns the command handler since this will not let through any states to subsequent match statements.
- returns
