Interface BayeuxContext

All Known Implementing Classes:
AbstractBayeuxContext

public interface BayeuxContext

The Bayeux Context provides information about the current context of a Bayeux message.

This information may be from an associated HTTP request, or a HTTP request used to originally establish the connection (for example in a websocket handshake).

    • getHeader

      String getHeader​(String name)
      Get a transport header.

      Parameters:
      name - The name of the header
      Returns:
      The header value or null if no current transport mechanism or no such header.
    • getParameter

      String getParameter​(String name)
      Get a transport parameter.

      Get a parameter for any current transport mechanism (eg HTTP request). For transports like websocket, the parameter may be from the initial handshake.

      Parameters:
      name - The name of the parameter
      Returns:
      The parameter value or null if no current transport mechanism or no such parameter.
    • getParameterValues

      List<String> getParameterValues​(String name)
      Get a multi valued transport parameter.

      Parameters:
      name - The name of the parameter
      Returns:
      The parameter value or null if no current transport mechanism or no such parameter.
    • getCookie

      String getCookie​(String name)
      Get a transport cookie.

      Get a cookie for any current transport mechanism (eg HTTP request). For transports like websocket, the cookie may be from the initial handshake.

      Parameters:
      name - The name of the cookie
      Returns:
      The cookie value or null if no current transport mechanism or no such cookie.
    • getHttpSessionId

      String getHttpSessionId()
      Access the HTTP Session (if any) ID. The Session.getId() should be used in preference to the HTTP Session.
      Returns:
      HTTP session ID or null
    • getHttpSessionAttribute

      Object getHttpSessionAttribute​(String name)
      Access the HTTP Session (if any) attributes. The Session.getAttribute(String) should be used in preference to the HTTP Session.

      Returns:
      The attribute value
    • setHttpSessionAttribute

      void setHttpSessionAttribute​(String name, Object value)
      Access the HTTP Session (if any) attributes. The Session.setAttribute(String, Object) should be used in preference to the HTTP Session.
      Parameters:
      name - the attribute name
      value - the attribute value
    • invalidateHttpSession

      void invalidateHttpSession()
      Invalidate the HTTP Session. The Session.getId() should be used in preference to the HTTP Session.
    • getRequestAttribute

      Object getRequestAttribute​(String name)
