Class Resolver<T>

java.lang.Object

org.restlet.util.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:

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)
response.entity.expirationDate	EED	Date (HTTP format)
request.entity.language	el	String
response.entity.language	EL	String
request.entity.modificationDate	emd	Date (HTTP format)
response.entity.modificationDate	EMD	Date (HTTP format)
request.entity.mediaType	emt	String
response.entity.mediaType	EMT	String
request.entity.size	es	Integer
response.entity.size	ES	Integer
request.entity.tag	et	String
response.entity.tag	ET	String
request.referrerRef	f*	Reference (see table below variable name sub-parts)
request.hostRef	h*	Reference (see table below variable name sub-parts)
request.method	m	String
request.rootRef	o*	Reference (see table below variable name sub-parts)
request.protocol	p	String
request.resourceRef	r*	Reference (see table below variable name sub-parts)
response.redirectRef	R*	Reference (see table below variable name sub-parts)
response.status	S	Integer
response.serverInfo.address	SIA	String
response.serverInfo.agent	SIG	String
response.serverInfo.port	SIP	Integer

Below is the list of name sub-parts, for Reference variables, that can replace the asterix in the variable names above:

Reference property	Sub-part name	Content type
authority	a	String
baseRef	b*	Reference
targetRef	t*	Reference
relativePart	e	String
fragment	f	String
hostIdentifier	h	String
identifier	i	String
path	p	String
query	q	String
remainingPart	r	String
