      Enum Constants 
      Enum Constant Description
      BUNDLE
      When the component is registered as a service, it must be registered as a bundle scope service and an instance of the component must be created for each bundle using the service.
      DEFAULT
      Default element value for annotation.
      PROTOTYPE
      When the component is registered as a service, it must be registered as a prototype scope service and an instance of the component must be created for each distinct request for the service.
      SINGLETON
      When the component is registered as a service, it must be registered as a bundle scope service but only a single instance of the component must be used for all bundles using the service.

      • values

        public static ServiceScope[] 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 (ServiceScope c : ServiceScope.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ServiceScope 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
