      Modifier and Type Method Description
      java.lang.Class<?> type()
      The type of the extension point
      static ExtensionPoints valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name.
      static ExtensionPoints[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.

      • CONFIGURATION_SETTING

        public static final ExtensionPoints CONFIGURATION_SETTING
        An extension that contributes a ConfigurationSetting.

        Plugins are not encouraged to contribute additional ConfigurationSettings as each additional setting adds to the complexity of configuring and maintaining product deployments. When a setting is unavoidable a plugin must advertise the ConfigurationSettings that it introduces.

      • HTTP_FILTER

        public static final ExtensionPoints HTTP_FILTER
        An extension that contributes a servlet Filter. The filter must be annotated with the Priority annotation and use one of the rings defined by FilterOrder to indicate at what stage in the filtering pipeline it should be invoked. The filter will be invoked for every request.

      • HTTP_SERVLET

        public static final ExtensionPoints HTTP_SERVLET
        An Extension that contributes a HttpServlet. The implementation must be annotated with the Dispatches annotation to advertise the route patterns that it handles.

      • LIFECYCLE

        public static final ExtensionPoints LIFECYCLE
        An Extension that participates in the application startup and/or shutdown process. If the order in which a provider is invoked is important, then the implementation type should be annotated with Priority to indicate where in the startup/shutdown cycle it should be invoked.

      • values

        public static ExtensionPoints[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (ExtensionPoints c : ExtensionPoints.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ExtensionPoints valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • type

        public java.lang.Class<?> type()
        The type of the extension point
        Returns:
        The extension point type
