Enum SizeUnit

java.lang.Object

java.lang.Enum<SizeUnit>

com.vip.vjtools.vjkit.number.SizeUnit

All Implemented Interfaces:

Serializable, Comparable<SizeUnit>

public enum SizeUnit
extends Enum<SizeUnit>

Representation of basic size units，just like TimeUnit. Usage example: assertTrue(SizeUnit.BYTES.toMegaBytes(1024 * 1024) == 1.0);
assertTrue(SizeUnit.GIGABYTES.toBytes(1) == 1024.0 * 1024.0 * 1024.0);

KILOBYTES

public static final SizeUnit KILOBYTES

"One thousand" (1024) bytes.

MEGABYTES

public static final SizeUnit MEGABYTES

"One million" (1024x1024) bytes.

Method Detail

values

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

Returns:

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

valueOf

public static SizeUnit 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

toBytes

public double toBytes(long input)

Returns the number of bytes corresponding to the provided input for a particular unit of memory.

Parameters:

input - Number of units of memory.

Returns:

Number of bytes corresponding to the provided number of particular memory units.

toKiloBytes

public double toKiloBytes(long input)

Returns the number of kilobytes corresponding to the provided input for a particular unit of memory.

Parameters:

input - Number of units of memory.

Returns:

Number of kilobytes corresponding to the provided number of particular memory units.

toMegaBytes

public double toMegaBytes(long input)

Returns the number of megabytes corresponding to the provided input for a particular unit of memory.

Parameters:

input - Number of units of memory.

Returns:

Number of megabytes corresponding to the provided number of particular memory units.

toGigaBytes

public double toGigaBytes(long input)

Returns the number of gigabytes corresponding to the provided input for a particular unit of memory.

Parameters:

input - Number of units of memory.

Returns:

Number of gigabytes corresponding to the provided number of particular memory units.
