Method Summary

Modifier and Type	Method	Description
static boolean	isPrimitive(Type type)	Returns true if this type is a primitive.
static boolean	isWrapperType(Type type)	Returns true if type is one of the nine primitive-wrapper types, such as Integer.
static <T> Class<T>	unwrap(Class<T> type)	Returns the corresponding primitive type of type if it is a wrapper type; otherwise returns type itself.
static <T> Class<T>	wrap(Class<T> type)	Returns the corresponding wrapper type of type if it is a primitive type; otherwise returns type itself.

wrap

public static <T> Class<T> wrap(Class<T> type)

Returns the corresponding wrapper type of type if it is a primitive type; otherwise returns type itself. Idempotent.

    wrap(int.class) == Integer.class
    wrap(Integer.class) == Integer.class
    wrap(String.class) == String.class

unwrap

public static <T> Class<T> unwrap(Class<T> type)

Returns the corresponding primitive type of type if it is a wrapper type; otherwise returns type itself. Idempotent.

    unwrap(Integer.class) == int.class
    unwrap(int.class) == int.class
    unwrap(String.class) == String.class
