Class Resolver<T>

  • public abstract class Resolver<T>
extends java.lang.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:
    list of supported variables
    Model property Variable name Content type
    request.confidential c boolean (true|false)
    request.clientInfo.address cia String
    request.clientInfo.upstreamAddress ciua String
    request.clientInfo.agent cig String
    request.challengeResponse.identifier cri String
    request.challengeResponse.scheme crs String
    request.date d Date (HTTP format)
    request.entity.characterSet ecs String
    response.entity.characterSet ECS String
    request.entity.encoding ee String
    response.entity.encoding EE String
    request.entity.expirationDate eed Date (HTTP format)
