org.apache.struts2.dispatcher.mapper
public interface: ActionMapper [javadoc | source]

All Known Implementing Classes:
DefaultActionMapper, Restful2ActionMapper, CompositeActionMapper, RestfulActionMapper

Provide a mapping between HTTP requests and action invocation requests and vice-versa.

When given an HttpServletRequest, the ActionMapper may return null if no action invocation request matches, or it may return an ActionMapping that describes an action invocation for the framework to try.

The ActionMapper is not required to guarantee that the ActionMapping returned be a real action or otherwise ensure a valid request. Accordingly, most ActionMappers do not need to consult the Struts configuration just to determine if a request should be mapped.

Just as requests can be mapped from HTTP to an action invocation, the opposite is true as well. However, because HTTP requests (when shown in HTTP responses) must be in String form, a String is returned rather than an actual request object.
