Method Detail

getUnitType

protected UnitsConstants getUnitType()

Specified by:

getUnitType in class SimpleFormatter

getUnitScale

protected ScaleConstants getUnitScale()

Specified by:

getUnitScale in class SimpleFormatter

formatNumber

protected FormattedNumber formatNumber(double rawValue,
                                       NumberFormat fmt)

Specified by:

formatNumber in class SimpleFormatter

parse

public UnitNumber parse(String val,
                        Locale locale,
                        ParseSpecifics specifics)
                 throws ParseException

Description copied from interface: Formatter

Parse a string into a UnitNumber. E.x. parse("34 MB") -> UnitNumber(34, UNIT_BYTES, SCALE_MEGA)

Specified by:

parse in interface Formatter

Overrides:

parse in class SimpleFormatter

Parameters:

val - Value to parse

locale - Locale to parse with

specifics - An optional argument which gives the parser more information about parsing

Returns:

the number representing the parsed value

Throws:

ParseException - if the value could not be parsed

formatSame

public FormattedNumber[] formatSame(double[] vals,
                                    UnitsConstants unitType,
                                    ScaleConstants scale,
                                    Locale locale,
                                    FormatSpecifics specifics)

Description copied from interface: Formatter

Format a several values at once into the same format. I.e. no matter the discrepency of range, they all contain the same units (megabytes, etc.)

Specified by:

formatSame in interface Formatter

Overrides:

formatSame in class SimpleFormatter

Parameters:

vals - Values to format

unitType - One of UnitsConstants.UNIT_*

scale - One of UnitsConstants.SCALE_*

locale - Locale that the resultant format should be in

specifics - Optional format to give specific hints to the formatter about how the result should look.
