Understanding Interceptors in Dependency Injection
Interceptors are objects that can intercept and modify the behavior of other objects or systems. In the context of dependency injection, interceptors are objects that can intercept and modify the behavior of dependencies before they are injected into other objects or systems.
For example, an interceptor might be used to:
* Log information about the dependencies being injected
* Add additional functionality to the dependencies
* Modify the behavior of the dependencies based on certain conditions
* Provide a way to inject fake or mock dependencies for testing purposes
Interceptors can be useful in a variety of situations, such as:
* Logging information about the dependencies being injected
* Adding additional functionality to the dependencies
* Modifying the behavior of the dependencies based on certain conditions
* Providing a way to inject fake or mock dependencies for testing purposes
Here are some examples of interceptors that might be used in a dependency injection system:
* A logging interceptor that logs information about the dependencies being injected
* An authentication interceptor that adds authentication functionality to the dependencies
* A caching interceptor that caches the results of dependency lookups to improve performance
* A mocking interceptor that provides fake or mock dependencies for testing purposes.
