The Handler pattern is a behavioral design pattern that is used to send requests to multiple handlers and prioritize them for sequential processing.
The Handler pattern allows a request to be sent to multiple handlers, with each handler having the opportunity to process the request. This approach can effectively reduce code coupling, making the system more flexible and scalable.
The Handler pattern allows for dynamically adding or removing handlers, thus allowing for flexible adjustment of the order and priority of handlers.
The handler pattern can avoid the use of numerous if-else statements, improving the readability and maintainability of the code.
The Handler pattern can be used to implement the Chain of Responsibility pattern, allowing requests to be passed along a chain of handlers until one of them handles the request.
Handler pattern typically consists of an abstract handler class and concrete handler classes, allowing users to customize handler classes as needed to process requests.
