public enum MemoryUnit
extends Enum<MemoryUnit>

A collection of useful methods to deal with memory units.

The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. The international standard IEC 80000-13 codified this common meaning. The popularity of major commercial computing architectures has aided in the ubiquitous acceptance of the 8-bit size.

Method Detail

values

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

Returns:

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

valueOf

public static MemoryUnit 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

getByteValue

public double getByteValue()

Returns the number of bytes in the unit.

Returns:

Number of bytes in the unit.

Since:

2.0.0

extract

public static MemoryUnit extract(double value)

Extracts the closest equivalent in Bytes.

Note: The smallest unit returned is KIBI_BYTE

Parameters:

value - for which the byte equivalent is to be extracted

Returns:

Closest byte equivalent of the provided number

Throws:

IllegalArgumentException - when a negative number is passed

Since:
