Method Detail

values

public static ObjectUtils[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ObjectUtils c : ObjectUtils.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ObjectUtils valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

immutabile

public static void immutabile(Class clazz,
                              boolean isImmutable)

isImmutable

public static ObjectUtils.Immutability isImmutable(@NotNull
                                                   Class clazz)

isTrue

public static boolean isTrue(CharSequence s)

isFalse

public static boolean isFalse(CharSequence s)

primToWrapper

public static Class primToWrapper(Class eClass)

If the class is a primitive type, change it to the equivalent wrapper.

Parameters:

eClass - to check

Returns:

the wrapper class if eClass is a primitive type, or the eClass if not.
