Method Detail
values
public static DataUnit[] 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 (DataUnit c : DataUnit.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
valueOf
public static DataUnit 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 nameNullPointerException- if the argument is null
fromSuffix
public static DataUnit fromSuffix(String suffix)
Return theDataUnitmatching the specifiedsuffix.- Parameters:
suffix- one of the standard suffixes- Returns:
- the
DataUnitmatching the specifiedsuffix - Throws:
IllegalArgumentException- if the suffix does not match the suffix of any of this enum's constants
