Field Summary

static Type<Object>

TYPE_OF_OBJECT The Type instance which represents the Object class

Method Summary

static <T> Type<T>	componentTypeOf(T[] object) Resolve the (element) component type for the given array.
static <T> Type<T>	elementTypeOf(Iterable<T> object) Resolve the nested element type for the given Iterable.
static <E> Type<E>	limitedValueOf(Class<E> rawType, Set<Type> recursiveBounds, Type... actualTypeArguments)
static <T> Type<T>	limitedValueOf(ParameterizedType type, Set<Type> recursiveBounds) Return the Type for the given ParameterizedType, resolving actual type arguments where possible; uses recursiveBounds to limit the recursion.
static <T> Type<T>	limitedValueOf(Type type, Set<Type> recursiveBounds) Return the Type for the given java.lang.reflect.Type, limiting the recursive depth on any type already contained in recursiveBounds.
static <T> Type<T>	limitedValueOf(TypeVariable<?> var, Set<Type> recursiveBounds) Finds the Type value of the given TypeVariable, using recursiveBounds to limit the recursion.
static <T> Type<T>	limitedValueOf(WildcardType var, Set<Type> recursiveBounds) Finds the Type value of the given wildcard type, using recursiveBounds to limit the recursion.
static <T> Type<T>	resolveTypeOf(T object, Type<?> referenceType) Resolve the Type for the given object, using the provided referenceType to resolve the actual type arguments.
static <T> Type<T>	resolveValueOf(Class<T> type, Type<?> referenceType) Resolve the Type for the given Class, using the provided referenceType to resolve the actual type arguments.
static <T> Type<T>	resolveValueOf(ParameterizedType type, Type<?> referenceType) Resolve the Type for the given ParameterizedType, using the provided referenceType to resolve any unresolved actual type arguments.
static <T> Type<T>	typeOf(T object) Return the Type for the given object.
static <E> Type<E>	valueOf(Class<E> rawType) Resolves the Type value of the specified raw Class type
static <E> Type<E>	valueOf(Class<E> rawType, Type... actualTypeArguments) Resolve the Type value of the given raw Class type, filling the type parameters with the provided actual type arguments
static <T> Type<T>	valueOf(ParameterizedType type) Return the Type for the given ParameterizedType, resolving actual type arguments where possible.
static Type<?>	valueOf(String typeDescriptor) Constructs a nested type from a string description of that type; allows for package names to be omitted for 'java.lang' and 'java.util' classes.
static <T> Type<T>	valueOf(Type type) Return the Type for the given java.lang.reflect.Type, either for a ParameterizedType or a Class instance
static <T> Type<T>	valueOf(Type<T> type) This method declaration helps to shortcut the other methods for ParameterizedType which it extends; we just return it.
static <T> Type<T>	valueOf(TypeVariable<?> var) Finds the Type value of the given TypeVariable
static <T> Type<T>	valueOf(WildcardType var) Finds the Type value of the given wildcard type
