Enum Constant Detail

MM

public static final LengthUnit MM

The millimetre.

CM

public static final LengthUnit CM

The centimetre.

INCH

public static final LengthUnit INCH

The inch.

PICA

public static final LengthUnit PICA

The pica (12pt i.e. 1/6in).

POINT

public static final LengthUnit POINT

The point (1/72in).

Method Detail

values

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

Returns:

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

valueOf

public static LengthUnit 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

getSymbol

public final String getSymbol()

The symbol for this unit of length.

Returns:

the symbol, eg "cm".

convertTo

public final BigDecimal convertTo(BigDecimal d,
                                  LengthUnit other)

Convert from this unit to another.

Parameters:

d - a length, eg 1.

other - another unit, eg CM.

Returns:

the rounded result, eg 2.54 if this is INCH

convertTo

public final BigDecimal convertTo(BigDecimal d,
                                  LengthUnit other,
                                  MathContext mc)

convertTo

public final Number convertTo(Number d,
                              LengthUnit other,
                              MathContext mc)

Convert from this unit to another. If d is a Float or Double then native operators are used, otherwise it is converted to BigDecimal and converted using mc. NOTE : this method doesn't always return the same type that it was passed, e.g. passing (int)1 can return new BigDecimal("2.54").

Parameters:

d - a length, e.g. 1.

other - another unit, e.g. CM.

mc - only used if d is not a Float or Double.

Returns:

the result, e.g. 2.54 if this is INCH.

convertTo

public final double convertTo(double d,
                              LengthUnit other)

convertTo

public final float convertTo(float d,
                             LengthUnit other)

format

public final String format(Number n)

getCommonUnit

public final LengthUnit getCommonUnit(LengthUnit o)

fromSymbol

public static final LengthUnit fromSymbol(String s)

parseLength

public static final Length parseLength(String l)

parseLength

public static final BigDecimal parseLength(String l,
                                           LengthUnit to)

Parse a length.

Parameters:

l - the length, can be null, e.g. "2.0cm".

to - the result unit, e.g. MM.

Returns:

the parsed length, null if l is, e.g. 20.

parsePositiveLength

public static final BigDecimal parsePositiveLength(String l,
                                                   LengthUnit to,
                                                   boolean strict)
