Class ChainedResourceResolver

  • All Implemented Interfaces:

    public class ChainedResourceResolver
    extends java.lang.Object
    implements ResourceResolver
    An ResourceResolver that first tries one supplied ResourceResolver, and if that returns null, falls back to another. Either ResourceResolver may itself be a ChainedResourceResolver, so a chain of any length can be established.

        public javax.xml.transform.Source resolve​(ResourceRequest request)

        Description copied from interface: ResourceResolver
        Process a resource request to deliver a resource
        Specified by:
        resolve in interface ResourceResolver
        request - the resource request
        the returned Source; or null to delegate resolution to another resolver. The type of Source must correspond to the type of resource requested: for non-XML resources, it should generally be a StreamSource.
        XPathException - if the request is invalid in some way, or if the identified resource is unsuitable, or if resolution is to fail rather than being delegated to another resolver.
