  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ReferenceScope>

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      BUNDLE
      A single service object is used for all references to the service in this bundle.
      PROTOTYPE
      If the bound service has prototype service scope, then each instance of the component with this reference can receive a unique instance of the service.
      PROTOTYPE_REQUIRED
      Bound services must have prototype service scope.

      • BUNDLE

        public static final ReferenceScope BUNDLE
        A single service object is used for all references to the service in this bundle.

      • PROTOTYPE

        public static final ReferenceScope PROTOTYPE
        If the bound service has prototype service scope, then each instance of the component with this reference can receive a unique instance of the service. If the bound service does not have prototype service scope, then this reference scope behaves the same as BUNDLE.

      • PROTOTYPE_REQUIRED

        public static final ReferenceScope PROTOTYPE_REQUIRED
        Bound services must have prototype service scope. Each instance of the component with this reference can receive a unique instance of the service.

    • Method Detail

      • values

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

      • valueOf

        public static ReferenceScope 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
