Apache Struts API Documentation: Interface ConfigHelperInterface

org.apache.struts.config Interface ConfigHelperInterface

All Known Implementing Classes:

ConfigHelper

public interface ConfigHelperInterface

NOTE: THIS CLASS IS UNDER ACTIVE DEVELOPMENT. THE CURRENT CODE IS WRITTEN FOR CLARITY NOT EFFICIENCY. NOT EVERY API FUNCTION HAS BEEN IMPLEMENTED YET. A helper object to expose the Struts shared resources, which are be stored in the application, session, or request contexts, as appropriate. An instance should be created for each request processed. The methods which return resources from the request or session contexts are not thread-safe. Provided for use by other servlets in the application so they can easily access the Struts shared resources. The resources are stored under attributes in the application, session, or request contexts. The ActionConfig methods simply return the resources from under the context and key used by the Struts ActionServlet when the resources are created.

Since:

Struts 1.1
