Constructor Details

UnitsConverter

public UnitsConverter(String sourceIdentifier,
 String targetIdentifier)

Constructor of UnitsConverter. NOTE: - source and target must be under the same category - e.g. meter to mile --> both of them are length units.

NOTE: This constructor creates an instance of UnitsConverter internally.

Parameters:

sourceIdentifier - represents the source unit identifier.

targetIdentifier - represents the target unit identifier.

UnitsConverter

public UnitsConverter(MeasureUnitImpl source,
 MeasureUnitImpl target,
 ConversionRates conversionRates)

Constructor of UnitsConverter. NOTE: - source and target must be under the same category - e.g. meter to mile --> both of them are length units. This converts from source to base to target (one of those may be a no-op).

Parameters:

source - represents the source unit.

target - represents the target unit.

conversionRates - contains all the needed conversion rates.
