Commands make team development easier Another advantage of using commands to break your application logic into individual actions is that you and your teammates can more easily develop individual features in isolation. Controller classes frequently lead to merge-headaches when you try to resolve conflicting changes. Commands result in fewer merge problems, and also make it easier to distinguish between ‘same purpose’ repeated code and incidental repeated code. Detain and release when you need your command to hang around Most commands are short-lived, but occasionally you may want to keep your command alive to handle a response from an asynchronous service call and then take action based on the result.
Don’t imagine it as part of your view layer—adding view logic to mediators gets messy very quickly. Just use your mediator to translate application events into actions on the view API, and view-events into application events, and you’ll stay out of trouble. The CommandMap makes things happen You use the CommandMap to ‘map’ events to one or more commands, which should be executed when the event specified occurs. A command is just a class which has a public execute() method. You typically use commands to interact with your models and services.
This ‘tying together’ is the realm of the controller code—and it’s usually the most complex and brittle code in your application. The CommandMap and the Command class exist to achieve this ‘tying together’ in a way that is less complex and less brittle than the typical controller approach. A Command is a concise single-purpose controller object The Command Pattern is a strategy for separating your controller logic into small selfcontained pieces. Instead of having a monolithic MosaicController, we can separate the logic for the Mosaic application into self-describing, single-purpose classes: Example 6-1.
