Class ResourceResolverDelegate

java.lang.Object

net.sf.saxon.lib.ResourceResolverDelegate

All Implemented Interfaces:

ResourceResolver

public class ResourceResolverDelegate
extends java.lang.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.

Constructor Detail

ResourceResolverDelegate

public ResourceResolverDelegate(java.util.function.Function<ResourceRequest,javax.xml.transform.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.

Method Detail

resolve

public javax.xml.transform.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.
