Direct Known Subclasses:

WrapperRequest

public class Request

getHostRef

public Reference getHostRef()

Returns the host reference. This may be different from the resourceRef's host, for example for URNs and other URIs that don't contain host information.

Note that when used with HTTP connectors, this property maps to the "Host" header.

Returns:

The host reference.

getMaxForwards

public int getMaxForwards()

Returns the maximum number of intermediaries.

Returns:

The maximum number of intermediaries.

getMethod

public Method getMethod()

Returns the method.

Returns:

The method.

getOnResponse

public Uniform getOnResponse()

Returns the callback invoked on response reception. If the value is not null, then the associated request will be executed asynchronously.

Returns:

The callback invoked on response reception.

getOriginalRef

public Reference getOriginalRef()

Returns the original reference as requested by the client. Note that this property is not used during request routing. See the getResourceRef() method for details.

See Also:

getResourceRef()

getProtocol

getReferrerRef

public Reference getReferrerRef()

Returns the referrer reference if available. Note that when used with HTTP connectors, this property maps to the "Referer" header.

Returns:

The referrer reference.

getResourceRef

public Reference getResourceRef()

Returns the reference of the target resource. This reference is especially important during routing, dispatching and resource finding. During such processing, its base reference is constantly updated to reflect the reference of the parent Restlet or resource and the remaining part of the URI that must be routed or analyzed. If you need to get the URI reference originally requested by the client, then you should use the getOriginalRef() method instead. Also, note that beside the update of its base property, the resource reference can be modified during the request processing. For example, the org.restlet.client.service.TunnelService associated to an application can extract some special extensions or query parameters and replace them by semantically equivalent properties on the request object. Therefore, the resource reference can become different from the original reference. Finally, when sending out requests via a dispatcher such as Context.getClientDispatcher() or Context#getServerDispatcher(), if the reference contains URI template variables, those variables are automatically resolved using the request's attributes.

Returns:

The reference of the target resource.

getOriginalRef(), getHostRef()

getRootRef

public Reference getRootRef()

Returns the application root reference.

Returns:

The application root reference.
