cn.taketoday.util.DataUnit

所有已实现的接口:

Serializable, Comparable<DataUnit>, Constable

public enum DataUnit
extends Enum<DataUnit>

A standard set of DataSize units.

The unit prefixes used in this class are binary prefixes indicating multiplication by powers of 2. The following table displays the enum constants defined in this class and corresponding values.

Constant	Data Size	Power of 2	Size in Bytes
BYTES	1B	2^0	1
KILOBYTES	1KB	2^10	1,024
MEGABYTES	1MB	2^20	1,048,576
GIGABYTES	1GB	2^30	1,073,741,824
TERABYTES	1TB	2^40	1,099,511,627,776

从以下版本开始:

values

public static DataUnit[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

返回:

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

valueOf

public static DataUnit valueOf(String name)

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

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

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

NullPointerException - 如果参数为空值

size

DataSize size()

fromSuffix

public static DataUnit fromSuffix(String suffix)

Return the DataUnit matching the specified suffix.

参数:

suffix - one of the standard suffixes

返回:

the DataUnit matching the specified suffix

抛出:

IllegalArgumentException - if the suffix does not match the suffix of any of this enum's constants
