Direct Known Subclasses:
CallResolver, MapResolver
public abstract class Resolver<T> extends Object
Resolves a name into a value. By default, the createResolver(Map) static method can adapt a Java map into a resolver. Another useful method is createResolver(Request, Response), which can expose a Restlet call into a compact data model, with the following variables:
