Method Detail

values

public static StringUtils.TraditionalBinaryPrefix[] 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 (StringUtils.TraditionalBinaryPrefix c : StringUtils.TraditionalBinaryPrefix.values())
    System.out.println(c);

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

valueOf

public static StringUtils.TraditionalBinaryPrefix 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

valueOf

public static StringUtils.TraditionalBinaryPrefix valueOf(char symbol)
Returns:
The TraditionalBinaryPrefix 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;

Parameters:
s - input string
Returns:
a long value represented by the input string.
