Examples of org.restlet.resource.ClientResource

org.restlet.resource.ClientResource
Client-side resource. Acts like a proxy of a target resource.
This class changes the semantics of the {@link UniformResource#getRequest()}and {@link UniformResource#getResponse()} methods. Since a clientResource mayreceive severals responses for a single request (in case of interim response), the {@link #getResponse()} method returns the last receivedresponse object. The Request object returned by the {@link #getRequest()} isactually a prototype which is cloned (except the representation) just before the {@link #handle()} method is called.
Users must be aware that by most representations can only be read or written once. Some others, such as {@link StringRepresentation} stored the entity inmemory which can be read several times but has the drawback to consume memory.
Concurrency note: instances of the class are not designed to be shared among several threads. If thread-safety is necessary, consider using the lower-level {@link Client} class instead. @author Jerome Louvel
