org.ka2ddo.util.WeightUnit

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<WeightUnit>, UnitEnum<WeightUnit>

public enum WeightUnit
extends java.lang.Enum<WeightUnit>
implements UnitEnum<WeightUnit>

This enumeration declares units (with conversion factors) for measuring weights (including units of mass that are commonly used for weight in one standard Earth gravity).

Method Detail

values

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

Returns:

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

valueOf

public static WeightUnit 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

from

public final float from(WeightUnit other)

Get the multiplicative conversion factor to convert a weight from the specified units to this unit.

Specified by:

from in interface UnitEnum<WeightUnit>

Parameters:

other - another WeightUnit representing the existing units of a Weight value

Returns:

the conversion factor to change a Weight value into this unit

getOffset

public float getOffset(WeightUnit other)

Get the additive offset to convert a value from the specified unit to this unit.

Specified by:

getOffset in interface UnitEnum<WeightUnit>

Parameters:

other - another WeightUnit representing the existing units of a value

Returns:

the offset (after multiplying by the from() factor) to add to get the value in this unit

getAbbreviation

public java.lang.String getAbbreviation()

Get short standard abbreviations for this WeightUnit.

Returns:

abbreviations string

getUnitForName

public static WeightUnit getUnitForName(java.lang.String name)

Get the enumeration corresponding to the specified weight unit String name.

Parameters:

name - String to convert inti a WeightUnit

Returns:

WeightUnit corresponding to the String, or null if no matching WeightUnit

getHeavyWeightUnits

public static WeightUnit[] getHeavyWeightUnits()

Get the units of weight that are "heavy" (enough for a motorized vehicle).

Returns:

array of WeightUnits
