        public static ParameterizedTypeImpl of​(java.lang.Class<?> rawType,
                                       java.lang.reflect.Type... actualTypeArguments)
        Static factory. Given a (generic) class, actual type arguments and an owner type, creates a parameterized type. This class can be instantiated with a a raw type that does not represent a generic type, provided the list of actual type arguments is empty. If the ownerType argument is null, the declaring class of the raw type is used as the owner type.

        This method throws a MalformedParameterizedTypeException under the following circumstances: If the number of actual type arguments (i.e., the size of the array typeArgs) does not correspond to the number of formal type arguments. If any of the actual type arguments is not an instance of the bounds on the corresponding formal.

        Parameters:
        rawType - the Class representing the generic type declaration being instantiated
        actualTypeArguments - - a (possibly empty) array of types representing the actual type arguments to the parameterized type
        Returns:
        An instance of ParameterizedType
        Throws:
        java.lang.reflect.MalformedParameterizedTypeException - - if the instantiation is invalid

      • getActualTypeArguments

        public java.lang.reflect.Type[] getActualTypeArguments()
        Returns an array of Type objects representing the actual type arguments to this type.

        Note that in some cases, the returned array be empty. This can occur if this type represents a non-parameterized type nested within a parameterized type.

        Specified by:
        getActualTypeArguments in interface java.lang.reflect.ParameterizedType
        Returns:
        an array of Type objects representing the actual type arguments to this type

      • getRawType

        public java.lang.Class<?> getRawType()
        Returns the Type object representing the class or interface that declared this type.
        Specified by:
        getRawType in interface java.lang.reflect.ParameterizedType
        Returns:
        the Type object representing the class or interface that declared this type

      • getOwnerType

        public java.lang.reflect.Type getOwnerType()
        Returns a Type object representing the type that this type is a member of. For example, if this type is O.I, return a representation of O.

        If this type is a top-level type, null is returned.

        Specified by:
        getOwnerType in interface java.lang.reflect.ParameterizedType
        Returns:
        a Type object representing the type that this type is a member of. If this type is a top-level type, null is returned
