Method Details

getFactorToBase

private UnitsConverter.Factor getFactorToBase(SingleUnitImpl singleUnit)

Extracts the factor from a SingleUnitImpl to its Basic Unit.

Parameters:

singleUnit -

Returns:

getFactorToBase

public UnitsConverter.Factor getFactorToBase(MeasureUnitImpl measureUnit)

getOffset

protected BigDecimal getOffset(MeasureUnitImpl source,
 MeasureUnitImpl target,
 UnitsConverter.Factor sourceToBase,
 UnitsConverter.Factor targetToBase,
 UnitsConverter.Convertibility convertibility)

getSpecialMappingName

protected String getSpecialMappingName(MeasureUnitImpl simpleUnit)

extractCompoundBaseUnit

public MeasureUnitImpl extractCompoundBaseUnit(MeasureUnitImpl measureUnit)

extractBaseUnits

public ArrayList<SingleUnitImpl> extractBaseUnits(MeasureUnitImpl measureUnitImpl)

extractBaseUnits

public ArrayList<SingleUnitImpl> extractBaseUnits(SingleUnitImpl singleUnit)

Parameters:

singleUnit - An instance of SingleUnitImpl.

Returns:

The base units in the SingleUnitImpl with applying the dimensionality only and not the SI prefix.

NOTE: This method is helpful when checking the convertibility because no need to check convertibility.

extractSystems

public String extractSystems(SingleUnitImpl singleUnit)

Returns:

The measurement systems for the specified unit.

checkSimpleUnit

private boolean checkSimpleUnit(MeasureUnitImpl measureUnitImpl)

Checks if the MeasureUnitImpl is simple or not.

Parameters:

measureUnitImpl -

Returns:

true if the MeasureUnitImpl is simple, false otherwise.
