Interface Server

All Superinterfaces:

Lifecycle

All Known Implementing Classes:

StandardServer

public interface Server
extends Lifecycle

A Server element represents the entire Catalina servlet container. Its attributes represent the characteristics of the servlet container as a whole. A Server may contain one or more Services, and the top level set of naming resources.

Normally, an implementation of this interface will also implement Lifecycle, such that when the start() and stop() methods are called, all of the defined Services are also started or stopped.

In between, the implementation must open a server socket on the port number specified by the port property. When a connection is accepted, the first line is read and compared with the specified shutdown command. If the command matches, shutdown of the server is initiated.

NOTE - The concrete implementation of this class should register the (singleton) instance with the ServerFactory class in its constructor(s).
