Method Summary

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.

Method Detail

Class.isPrimitive()

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
