Enum ByteSizeUnit

java.lang.Object

java.lang.Enum<ByteSizeUnit>

org.pfsw.text.ByteSizeUnit

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ByteSizeUnit>

public enum ByteSizeUnit
extends java.lang.Enum<ByteSizeUnit>

This enum provides several memory size units with an associated factor that is useful to calculate the number of bytes from a value given in a different memory size unit. See also http://en.wikipedia.org/wiki/IEEE_1541-2002

Method Detail

values

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

Returns:

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

valueOf

public static ByteSizeUnit 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

findByPrefix

public static ByteSizeUnit findByPrefix(java.lang.String str)

Returns the ByteSiteUnit enum value that matches the given string.

Parameters:

str - The prefix value to be used for the look-up.

Returns:

The found enum or null if not found.

getPowerOf1024

public int getPowerOf1024()

Returns the power of 1024 (bytes) this unit represents.

getCommonnName

public java.lang.String getCommonnName()

Returns the commonly used (but incorrect) name of the unit.

getCommonPrefix

public java.lang.String getCommonPrefix()

Returns the commonly used (but incorrect) short name of the unit.

getIEEE1541Name

public java.lang.String getIEEE1541Name()

Returns the standardized IEEE 1541 name of the unit.

getIEEE1541Prefix

public java.lang.String getIEEE1541Prefix()

Returns the standardized IEEE 1541 prefix of the unit.

getBytesFactor

public java.math.BigDecimal getBytesFactor()

Returns the multiplication factor for this unit to convert a corresponding value to its number of bytes.

getFactor

public long getFactor()

Returns the multiplication factor for this unit to convert a corresponding value to its number of bytes as long value.
