    • Method Detail

      • boxedType

        public static Type boxedType​(Type type)
        Gets the boxed type of a class
        Parameters:
        type - The type
        Returns:
        The boxed type

      • boxedClass

        public static Class<?> boxedClass​(Class<?> type)

      • getTypeId

        public static String getTypeId​(Type type)

      • getCanonicalType

        public static Type getCanonicalType​(Class<?> clazz)
        Returns a canonical type for a given class. If the class is a raw type of a parameterized class, the matching ParameterizedType (with unresolved type variables) is resolved. If the class is an array then the component type of the array is canonicalized Otherwise, the class is returned.
        Returns:

      • getCanonicalType

        public static Type getCanonicalType​(Type type)
        Parameters:
        type -
        Returns:

      • containsTypeVariable

        public static boolean containsTypeVariable​(Type type)

      • getRawTypes

        public static Set<Class<?>> getRawTypes​(Set<Type> types)

      • getRawTypes

        public static Class<?>[] getRawTypes​(Type[] types)

      • buildClassNameMap

        public static <C extends Class<?>> Map<String,​C> buildClassNameMap​(Iterable<C> set)
        Builds (class name -> class) map for given classes.

      • isActualType

        public static boolean isActualType​(Type type)
        Determines whether the given type is an actual type. A type is considered actual if it is a raw type, a parameterized type or an array type.
        Parameters:
        type - the given type
        Returns:
        true if and only if the given type is an actual type

      • isArray

        public static boolean isArray​(Type type)
        Determines whether the given type is an array type.
        Parameters:
        type - the given type
        Returns:
        true if the given type is a subclass of java.lang.Class or implements GenericArrayType

      • getArrayComponentType

        public static Type getArrayComponentType​(Type type)
        Determines the component type for a given array type.
        Parameters:
        type - the given array type
        Returns:
        the component type of a given array type

      • isArrayOfUnboundedTypeVariablesOrObjects

        public static boolean isArrayOfUnboundedTypeVariablesOrObjects​(Type[] types)
        Determines whether the given array only contains unbounded type variables or Object.class.
        Parameters:
        types - the given array of types
        Returns:
        true if and only if the given array only contains unbounded type variables or Object.class

      • isRawGenericType

        public static boolean isRawGenericType​(Type type)

      • isIllegalBeanType

        public static boolean isIllegalBeanType​(Type beanType)
        Parameters:
        beanType -
        Returns:
        true if the given type is not a legal bean type, false otherwise

      • isMoreSpecific

        public static boolean isMoreSpecific​(Type type1,
                                     Type type2)
        Parameters:
        type1 -
        type2 -
        Returns:
        true if the first type is more specific than the second type (is a subtype of), false otherwise
