This API is used to automatically engage interceptors required to support domain specific assertions at runtime, thus simplifying interceptor configuration a lot.
public interface PolicyInterceptorProvider extends InterceptorProvider {
// return the schema types of the asssertions that can be supported
Collection<QName> getAssertionTypes()
}Currently, CXF supports PolicyInterceptorProvider implementations for the following assertion types:
{http://schemas.xmlsoap.org/ws/2005/02/rm/policy}RMAssertion
{http://www.w3.org/2007/01/addressing/metadata}Addressing
{http://www.w3.org/2007/01/addressing/metadata}AnonymousResponses
{http://www.w3.org/2007/01/addressing/metadata}NonAnonymousResponsesalong with the WS-SecurityPolicy defined assertions.
In addition, the framework offers an API to refine domain expression(s) (xml elements describing policy subjects within a policy scope) in policy attachments. There is currently only one implementation for EndpointReferenceType domain expressions (matching over the address). Another implementation, using XPath expressions, is in work.
