Method Details

getType

public static Class<?> getType(@NotNull
 @NotNull Object o)

Returns the type of the given object

Parameters:

o - Object to get for

Returns:

The object type

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 the type itself.

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

wrapType

public static Type wrapType(Type type)

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 the type itself.

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

isWrapperType

public static boolean isWrapperType(Class<?> type)

Returns true if the specified type is one of the nine primitive-wrapper types, such as Integer.

Parameters:

type - Type to check
