Interception

There are cases where we need to do some operations before or after calling a single method or a number of methods. For example, we may need to log something before and after invoking all the methods in a component. Interception allows us to wrap the injecting dependency in a proxy object which can perform such operations before, after, around or instead of each method invocation. This proxy object can then be injected instead of the wrapped service. Ninject Interception extension creates such proxy wrappers on the fly, and allows us to intercept invocations of the wrapped service members. The following diagram shows how a service will be replaced with an intercepted one during the interception process.

Interception is one of the best practices for implementing Cross Cutting Concerns such as logging, caching, exception handling, or transaction processing.
