IResultInterceptor

IResultInterceptor is a concept found in various software development frameworks, particularly those dealing with asynchronous operations or network requests. It serves as a mechanism to intercept and modify the result of an operation before it is returned to the calling code. This interception allows for centralized handling of common tasks such as data transformation, error handling, logging, or caching.

When an operation completes and produces a result, an IResultInterceptor can be invoked. This interceptor receives the original result and can then perform its designated actions. For instance, it might parse raw JSON data into a specific object model, check for error codes within the result and throw custom exceptions, log the outcome of the operation for debugging purposes, or store the result in a cache for future use.

The primary benefit of using IResultInterceptor is to promote code reusability and separation of concerns. Instead of scattering result processing logic throughout the application, it can be consolidated within one or more interceptors. This makes the main operation logic cleaner and easier to understand. Furthermore, it facilitates the addition or modification of result handling behavior without altering the core operation code, enhancing maintainability and flexibility. Different interceptors can be chained together to perform a sequence of operations on the result.
