public abstract class Connector
extends Restlet

Restlet enabling communication between Components. "A connector is an abstract mechanism that mediates communication, coordination, or cooperation among components. Connectors enable communication between components by transferring data elements from one interface to another without changing the data." Roy T. Fielding

"Encapsulate the activities of accessing resources and transferring resource representations. The connectors present an abstract interface for component communication, enhancing simplicity by providing a clean separation of concerns and hiding the underlying implementation of resources and communication mechanisms" Roy T. Fielding

Concurrency note: instances of this class or its subclasses can be invoked by several threads at the same time and therefore must be thread-safe. You should be especially careful when storing state in member variables.
