                                               throws ServletException

Deprecated.

use configureContext(ServletContextHandler) instead

Parameters:

context - the ServletContext to use

Returns:

a configured WebSocketUpgradeFilter instance

Throws:

ServletException - if the filer cannot be configured

addMapping

public void addMapping(org.eclipse.jetty.http.pathmap.PathSpec spec,

Specified by:

addMapping in interface MappedWebSocketCreator

Parameters:

spec - the path spec to use

creator - the creator for the mapping

addMapping

@Deprecated
public void addMapping(PathSpec spec,
                       org.eclipse.jetty.websocket.servlet.WebSocketCreator creator)

Description copied from interface: MappedWebSocketCreator

Add a mapping.

Specified by:

addMapping in interface MappedWebSocketCreator

Parameters:

spec - the path spec to use

addMapping

public void addMapping(String spec,
                       org.eclipse.jetty.websocket.servlet.WebSocketCreator creator)

Description copied from interface: MappedWebSocketCreator

Add a mapping, of a pathspec to a WebSocketCreator.

Recognized Path Spec syntaxes
