This class implement a simple server model: one listener thread accepts on a socket and creates a new worker thread for each incoming connection. More advanced Endpoints will reuse the threads, use queues, etc. author:    James Duncan Davidson author:    Jason Hunter author:    James Todd author:    Costin Manolache author:    Gal Shachor author:    Yoav Shapira author:    Remy Maucherat Inner Class :public interface Handler Inner Class :protected class Acceptor implements Runnable Inner Class :protected class SocketProcessor implements Runnable Inner Class :protected class Worker implements Runnable Inner Class :public class WorkerStack Field Summary final public static  String CERTIFICATE_KEY      The Request attribute key for the client certificate chain. final public static  String CIPHER_SUITE_KEY      The Request attribute key for the cipher suite. final public static  String KEY_SIZE_KEY      The Request attribute key for the key size. final public static  String SESSION_ID_KEY      The Request attribute key for the session id. protected  int acceptorThreadCount      Acceptor thread count. protected  InetAddress address      Address for the server socket. protected  int backlog      Allows the server developer to specify the backlog that should be used for server sockets. protected  int curThreads      Current worker threads count. protected  int curThreadsBusy      Current worker threads busy count. protected  boolean daemon      The default is true - the created threads will be in daemon mode. protected  Executor executor      External Executor based thread pool. protected  Handler handler      Handling of accepted sockets. protected  boolean initialized      Track the initialization state of the endpoint. protected static  Log log      protected  int maxThreads      Maximum amount of worker threads. protected  String name      Name of the thread pool, which will be used for naming child threads. protected volatile  boolean paused      Will be set to true whenever the endpoint is paused. protected  int port      Server socket port. protected volatile  boolean running      Running state of the endpoint. protected  int sequence      Sequence number used to generate thread names. protected  ServerSocket serverSocket      Associated server socket. protected  ServerSocketFactory serverSocketFactory      Server socket factory. protected  StringManager sm      protected  int soLinger      Socket linger. protected  int soTimeout      Socket timeout. protected  boolean tcpNoDelay      Socket TCP no delay. protected  int threadPriority      Priority of the acceptor and poller threads. protected  WorkerStack workers      Available workers.

Field Detail CERTIFICATE_KEY final public static String CERTIFICATE_KEY(Code) The Request attribute key for the client certificate chain. CIPHER_SUITE_KEY final public static String CIPHER_SUITE_KEY(Code) The Request attribute key for the cipher suite. KEY_SIZE_KEY final public static String KEY_SIZE_KEY(Code) The Request attribute key for the key size. SESSION_ID_KEY final public static String SESSION_ID_KEY(Code) The Request attribute key for the session id. This one is a Tomcat extension to the Servlet spec. acceptorThreadCount protected int acceptorThreadCount(Code) Acceptor thread count. address protected InetAddress address(Code) Address for the server socket. backlog protected int backlog(Code) Allows the server developer to specify the backlog that should be used for server sockets. By default, this value is 100. curThreads protected int curThreads(Code) Current worker threads count. curThreadsBusy protected int curThreadsBusy(Code) Current worker threads busy count. daemon protected boolean daemon(Code) The default is true - the created threads will be in daemon mode. If set to false, the control thread will not be daemon - and will keep the process alive. executor protected Executor executor(Code) External Executor based thread pool. handler protected Handler handler(Code) Handling of accepted sockets. initialized protected boolean initialized(Code) Track the initialization state of the endpoint. log protected static Log log(Code) maxThreads protected int maxThreads(Code) Maximum amount of worker threads. name protected String name(Code) Name of the thread pool, which will be used for naming child threads. paused protected volatile boolean paused(Code) Will be set to true whenever the endpoint is paused. port protected int port(Code) Server socket port. running protected volatile boolean running(Code) Running state of the endpoint. sequence protected int sequence(Code) Sequence number used to generate thread names. serverSocket protected ServerSocket serverSocket(Code) Associated server socket. serverSocketFactory protected ServerSocketFactory serverSocketFactory(Code) Server socket factory. sm protected StringManager sm(Code) soLinger protected int soLinger(Code) Socket linger. soTimeout protected int soTimeout(Code) Socket timeout. tcpNoDelay protected boolean tcpNoDelay(Code) Socket TCP no delay. threadPriority protected int threadPriority(Code) Priority of the acceptor and poller threads. workers protected WorkerStack workers(Code) Available workers. Method Detail createWorkerThread protected Worker createWorkerThread()(Code) Create (or allocate) and return an available processor for use in processing a specific HTTP request, if possible.
