Method Summary

Methods

Modifier and Type	Method and Description
ServerEndpoint.ListenCookie	addListenEndpoint(ServerEndpoint.ListenEndpoint listenEndpoint) Adds listenEndpoint to this ListenContext's collection of ListenEndpoint instances for the ServerEndpoint it was passed to, starts a listen operation on listenEndpoint if necessary, and returns the ListenCookie for an active listen operation on listenEndpoint.

Method Detail

addListenEndpoint

ServerEndpoint.ListenCookie addListenEndpoint(ServerEndpoint.ListenEndpoint listenEndpoint)
                                              throws IOException

Adds listenEndpoint to this ListenContext's collection of ListenEndpoint instances for the ServerEndpoint it was passed to, starts a listen operation on listenEndpoint if necessary, and returns the ListenCookie for an active listen operation on listenEndpoint.

The returned ListenCookie must have been obtained from a ListenHandle returned from some invocation of ListenEndpoint.listen on a ListenEndpoint equivalent to listenEndpoint by Object.equals.

This method may start a new listen operation on listenEndpoint by invoking its listen method and returning the ListenCookie from the resulting ListenHandle, or it may return a ListenCookie for a listen operation previously started (but still active) on an equivalent ListenEndpoint. If this method does invoke listen on listenEndpoint and it throws an exception, then this method throws that exception.

The implementation of this method may invoke checkPermissions on listenEndpoint to verify that a party that it is operating on behalf of has all of the security permissions necessary to listen for requests on listenEndpoint.

Parameters:

listenEndpoint - the ListenEndpoint to add to this ListenContext and to return a ListenCookie for

Returns:

a ListenCookie that represents an active listen operation on listenEndpoint

Throws:

IOException - if an invocation of listen on listenEndpoint throws an IOException

SecurityException - if an invocation of checkPermissions or listen on listenEndpoint throws a SecurityException

IllegalStateException - if this method is invoked unexpectedly, such as before being passed to ServerEndpoint.enumerateListenEndpoints or after the invocation of ServerEndpoint.enumerateListenEndpoints that it was created for has returned

NullPointerException - if listenEndpoint is null
