Method Detail

values

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

Returns:

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

valueOf

public static SpaceUnit valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

convert

public long convert(long value,
                    SpaceUnit unit)

For example, to convert 2048 bytes to KB, use: SpaceUnit.KB.convert(2048L, SpaceUnit.Bytes).

Parameters:

value - space amount

unit - space unit

Returns:

convert amount

convertDecimal

public double convertDecimal(double value,
                             SpaceUnit unit)

For example, to convert 2048 bytes to KB, use: SpaceUnit.KB.convert(2048L, SpaceUnit.Bytes).

Parameters:

value - space amount

unit - space unit

Returns:

convert amount
