Method Detail

values

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

Returns:

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

valueOf

public static DistanceUnit 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

isBase

public boolean isBase()

convertTo

public double convertTo(double value,
                        DistanceUnit targetUnit)

How much is "value" in unit "this" exprimed in the unit "target"). For example:

 DistanceUnit.M.convertTo(1.0, DistanceUnit.MM)==1000.0
 

isSameBaseUnit

public boolean isSameBaseUnit(DistanceUnit target)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<DistanceUnit>

fromString

public static DistanceUnit fromString(java.lang.String val)

Returns:

null if this unit is unknown

getAllUnits

public DistanceUnit[] getAllUnits()

Returns:

the sorted list (from smallest to biggest) of units sharing the same base unit.

getBestUnit

public static DistanceUnit getBestUnit(double value,
                                       DistanceUnit unit)

Return the first unit that would give a value >=1
