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

      • valueOf

        public static QualifyingStrategy 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

      • qualifies

        Attempts to qualify the given Binding against the requirement Key.
        Parameters:
        requirement - The requirement key
        binding - The binding to qualify
        Returns:
        Qualifier annotation when the binding qualifies; otherwise null

      • selectFor

        static final QualifyingStrategy selectFor​(com.google.inject.Key<?> key)
        Selects the appropriate qualifying strategy for the given requirement Key.
        Parameters:
        key - The requirement key
        Returns:
        Qualifying strategy

      • qualify

        static final java.lang.annotation.Annotation qualify​(com.google.inject.Key<?> key)
        Computes a canonical Qualifier annotation for the given binding Key.
        Parameters:
        key - The key to qualify
        Returns:
        Qualifier for the key
