All Implemented Interfaces:

ActionWrapper, ActionInterceptor

public class PreparableInterceptor
extends BaseActionInterceptor

Prepares action by calling prepare() before action method invocation.

A typical use of this is to run some logic to load an object from the database, so that when parameters are set they can be set on this object. For example, suppose you have a User object with two properties: id and name. Provided that the params interceptor is called twice (once before and once after this interceptor), you can load the User object using the id property, and then when the second params interceptor is called the parameter user.name will be set, as desired, on the actual object loaded from the database.

Optionally, preparable interceptor injects request parameters that ends with ".id" or "Id" so you can immediately load objects from storage before preparing.
