所有已实现的接口:

Serializable, Comparable<TraditionalBinaryPrefix>

public enum TraditionalBinaryPrefix
extends Enum<TraditionalBinaryPrefix>

The traditional binary prefixes, kilo, mega, ..., exa, which can be represented by a 64-bit integer. TraditionalBinaryPrefix symbols are case insensitive.

枚举常量详细资料

KILO

public static final TraditionalBinaryPrefix KILO

MEGA

public static final TraditionalBinaryPrefix MEGA

GIGA

public static final TraditionalBinaryPrefix GIGA

TERA

public static final TraditionalBinaryPrefix TERA

方法详细资料

values

public static TraditionalBinaryPrefix[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

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

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static TraditionalBinaryPrefix valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

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 - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

getValue

public long getValue()

getSymbol

public char getSymbol()

toLong

public long toLong(long n)

toString

public String toString(long n)

valueOf

public static TraditionalBinaryPrefix valueOf(char symbol)

返回:

The object corresponding to the symbol.

string2long

public static long string2long(String s)

Convert a string to long. The input string is first be trimmed and then it is parsed with traditional binary prefix. For example, "-1230k" will be converted to -1230 * 1024 = -1259520; "891g" will be converted to 891 * 1024^3 = 956703965184;

参数:

s - input string

返回:

a long value represented by the input string.

long2String

public static String long2String(long n,
                                 String unit,
                                 int decimalPlaces)

Convert a long integer to a string with traditional binary prefix.

参数:

n - the value to be converted

unit - The unit, e.g. "B" for bytes.

decimalPlaces - The number of decimal places.

返回:

a string with traditional binary prefix.
