Method Summary

boolean	checkOrigin(String originHeaderValue) Check the value of the Origin header (See definition) the client passed during the opening handshake.
List<Extension>	getNegotiatedExtensions(List<Extension> requestedExtensions) Return the ordered list of extensions that this server will support given the requested extension list passed in.
String	getNegotiatedSubprotocol(List<String> requestedSubprotocols) Return the subprotocol this server endpoint has chosen from the requested list supplied by a client who wishes to connect, or none if there wasn't one this server endpoint liked.
boolean	matchesURI(URI uri) Answers whether the current configuration matches the given URI.
void	modifyHandshake(HandshakeRequest request, HandshakeResponse response) Called by the container after it has formulated a handshake response resulting from a well-formed handshake request.

Method Detail

getNegotiatedSubprotocol

String getNegotiatedSubprotocol(List<String> requestedSubprotocols)

Return the subprotocol this server endpoint has chosen from the requested list supplied by a client who wishes to connect, or none if there wasn't one this server endpoint liked. See Sending the Server's Opening Handshake

Parameters:

clientSubprotocolList -

Returns:

getNegotiatedExtensions

List<Extension> getNegotiatedExtensions(List<Extension> requestedExtensions)

Return the ordered list of extensions that this server will support given the requested extension list passed in. See Negotiating Extensions

Parameters:

extensions -

Returns:

checkOrigin

boolean checkOrigin(String originHeaderValue)

Check the value of the Origin header (See definition) the client passed during the opening handshake.

Parameters:

originHeaderValue -

Returns:

matchesURI

boolean matchesURI(URI uri)

Answers whether the current configuration matches the given URI.

Parameters:

uri -

Returns:

modifyHandshake

void modifyHandshake(HandshakeRequest request,
                     HandshakeResponse response)

Called by the container after it has formulated a handshake response resulting from a well-formed handshake request. The container has already has already checked that this configuration has a matching URI, determined the validity of the origin using the checkOrigin method, and filled out the negotiated subprotocols and extensions based on this configuration. Custom configurations may override this method in order to inspect the request parameters and modify the handshake response. and the URI checking also.

Parameters:

headers -

principal -

requestURI -
