## com.sas.actionprovider.support
Class HttpViewerSupport

    com.sas.actionprovider.support.HttpViewerSupport

All Implemented Interfaces:
  ActionProviderViewInterface, HttpActionProviderInterface, HttpActionProviderViewInterface, URLTemplateViewInterface

    public class HttpViewerSupport

implements HttpActionProviderViewInterface, URLTemplateViewInterface

Provides a common implementation of the `HttpActionProviderViewInterface` to which components may delegate their own implementations of that interface.

Transformation Bean Components that acquire their Actions via the ActionProvider Framework (APF) are required to implement that interface.

A basic understanding of the ActionProvider Framework, of which this class is a part, is recommended before attempting to use this class.

- For general information on the ActionProvider Framework, including an overview of how the primary classes of the framework work together, refer to the ``com.sas.actionprovider`` package documentation.

- For examples demonstrating how to use the ActionProvider Framework, including how to override default Actions or add new custom Actions, refer to the Samples Site.
