Class ResourceResolverDelegate

java.lang.Object
net.sf.saxon.lib.ResourceResolverDelegate
All Implemented Interfaces:
ResourceResolver
public class ResourceResolverDelegate extends Object implements ResourceResolver
Convenience class to allow a ResourceResolver to be implemented as a lambda expression. Needed for C# transpilation, so that ResourceResolvers can be supplied both as classes implementing an interface, and as lambda functions.

    • ResourceResolverDelegate

      public ResourceResolverDelegate(Function<ResourceRequest,Source> lambda)
      Create a ResourceResolver implemented using (typically) a lambda expression
      Parameters:
      lambda - a function, typically supplied as a lambda expression, to map satisfy a ResourceRequest and return a Source. Note that this doesn't mean the resource actually has to be fetched: the returned Source might simply contain a URI.

    • resolve

      public Source resolve(ResourceRequest request) throws XPathException
      Description copied from interface: ResourceResolver
      Process a resource request to deliver a resource
      Specified by:
      resolve in interface ResourceResolver
      Parameters:
      request - the resource request
      Returns:
      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.
      Throws:
      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.
