Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static Set<Class<?>>`	`allPrimitiveTypes()`	Returns an immutable set of all nine primitive types (including `void`).
`static Set<Class<?>>`	`allWrapperTypes()`	Returns an immutable set of all nine primitive-wrapper types (including `Void`).
`static boolean`	`isWrapperType(Class<?> 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
  - allPrimitiveTypes
```
public static Set<Class<?>> allPrimitiveTypes()
```
    Returns an immutable set of all nine primitive types (including void). Note that a simpler way to test whether a Class instance is a member of this set is to call Class.isPrimitive().

  - allWrapperTypes
```
public static Set<Class<?>> allWrapperTypes()
```
    Returns an immutable set of all nine primitive-wrapper types (including Void).

  - isWrapperType
```
public static boolean isWrapperType(Class<?> type)
```
    Returns true if type is one of the nine primitive-wrapper types, such as Integer.
    
    See Also:
    
    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
