Class RequestProcessingContext

java.lang.Object
  com.boylesoftware.cb2.presentation.servlet.RequestProcessingContext

public class RequestProcessingContext

extends java.lang.Object

Request processor creates an instance of this class and keeps it as a request attribute during the whole request processing procedure. This class represents a collection of data and references that do not change during single request processing.

This class is not used directly in actions and presentation elements, instead ActionContext is used, which provides access to everything an instance of this class can give you access to. However, in certain situations when you don't have an action context (for example in custom JSP tags implementations), you can use services of this class directly given that its instance can be always easily found by calling get(HttpServletRequest request) static method.
