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.

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.

    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.
