Field Detail

requestDispatcher

private final RequestDispatcher requestDispatcher

The request handler

serverSocket

final ServerSocket serverSocket

The server socket used to accept connections

securityContext

private final SecurityContext securityContext

The security context at the time of the listen.

closed

private boolean closed

Whether the listen handle has been closed.

connections

private final Set connections

Set of connections created by this listen handle

failureLock

private final Object failureLock

Used to throttle accept failures

acceptFailureTime

private long acceptFailureTime

acceptFailureCount

private int acceptFailureCount

Constructor Detail

SslListenHandle

SslListenHandle(RequestDispatcher requestDispatcher,
                ServerSocket serverSocket)
         throws IOException

Creates a listen handle

Throws:

IOException

Method Detail

acceptLoop

final void acceptLoop()

Handles new socket connections.

continueAfterAcceptFailure

private boolean continueAfterAcceptFailure(Throwable t)

Throttles the accept loop after ServerSocket.accept throws an exception, and decides whether to continue at all. The current code is borrowed from the JRMP implementation; it always continues, but it delays the loop after bursts of failed accepts.

toString

public String toString()

Returns a string representation of this object.

Overrides:

toString in class Object

serverConnection

SslServerEndpointImpl.SslServerConnection serverConnection(Socket socket)
                                                    throws IOException

Returns a connection for the specified socket.

Throws:

IOException

handleConnection

void handleConnection(SslServerEndpointImpl.SslServerConnection connection,
                      RequestDispatcher requestDispatcher)

Handles a newly accepted server connection.

getPort

private int getPort()

Returns the port on which this handle is listening.

close

public void close()

Description copied from interface: ServerEndpoint.ListenHandle

Stops listening for requests on the associated ListenEndpoint.

After this method has returned, no more requests will be dispatched to the RequestDispatcher for the listen operation represented by this ListenHandle, and the listen operation is no longer considered active. This method frees any resources associated with the listen operation.

Invoking this method terminates any requests that have been received because of the listen operation and dispatched to the associated RequestDispatcher but have not yet had their response output stream closed (see InboundRequest.abort); subsequent I/O operations on such requests will fail with an IOException, except some operations that may succeed because they only affect data in local I/O buffers.

Specified by:

close in interface ServerEndpoint.ListenHandle

noteConnectionClosed

void noteConnectionClosed(SslServerEndpointImpl.SslServerConnection connection)

Called when a connection is closed without a call to close on this listener.

getCookie

public ServerEndpoint.ListenCookie getCookie()

Description copied from interface: ServerEndpoint.ListenHandle

Returns a ListenCookie to identify the listen operation as the return value of the ListenContext.addListenEndpoint method.

Specified by:

getCookie in interface ServerEndpoint.ListenHandle

Returns:

a ListenCookie to identify the listen operation
