Holds the scale factor.

Constructor Details

MultiplyConverter

public MultiplyConverter(double factor)

Creates a multiply converter with the specified scale factor.

Parameters:

factor - the scaling factor.

Method Details

of

public static MultiplyConverter of(double factor)

Creates a multiply converter with the specified scale factor.

Parameters:

factor - the scaling factor.

getFactor

public double getFactor()

Returns the scale factor of this converter.

Specified by:

getFactor in interface tech.uom.lib.common.function.DoubleFactorSupplier

Returns:

the scale factor.

isIdentity

public boolean isIdentity()

Specified by:

isIdentity in interface javax.measure.UnitConverter

isSimpleCompositionWith

protected boolean isSimpleCompositionWith(AbstractConverter that)

Description copied from class: AbstractConverter

Non-API Guard for AbstractConverter.simpleCompose(AbstractConverter)

Specified by:

isSimpleCompositionWith in class AbstractConverter

Parameters:

that -

Returns:

whether or not a 'simple' composition of transformations is possible

simpleCompose

protected AbstractConverter simpleCompose(AbstractConverter that)

Description copied from class: AbstractConverter

Non-API Guarded by AbstractConverter.isSimpleCompositionWith(AbstractConverter)

Overrides:

simpleCompose in class AbstractConverter

Parameters:

that -

Returns:

a new AbstractConverter that adds no additional conversion step

inverseWhenNotIdentity

public MultiplyConverter inverseWhenNotIdentity()

Description copied from class: AbstractConverter

Non-API

Returns an AbstractConverter that represents the inverse transformation of this converter, for cases where the transformation is not the identity transformation.

Specified by:

inverseWhenNotIdentity in class AbstractConverter

Returns:

convertWhenNotIdentity

public double convertWhenNotIdentity(double value)

Description copied from class: AbstractConverter

Non-API

Specified by:

convertWhenNotIdentity in class AbstractConverter

Parameters:

value -

Returns:

transformed value

convertWhenNotIdentity

public BigDecimal convertWhenNotIdentity(BigDecimal value,
 MathContext ctx)
                                  throws ArithmeticException

Description copied from class: AbstractConverter

Non-API

Specified by:

convertWhenNotIdentity in class AbstractConverter

Parameters:

value -

ctx -

Returns:

transformed value

Throws:

ArithmeticException

transformationLiteral

public final String transformationLiteral()

Description copied from class: AbstractConverter

Non-API

Returns a String describing the transformation that is represented by this converter. Contributes to converter's toString method. If null or empty toString output becomes simplified.

getValue

public Double getValue()

Specified by:

getValue in interface tech.uom.lib.common.function.ValueSupplier<Double>

compareTo

public int compareTo(javax.measure.UnitConverter o)

Specified by:

compareTo in interface Comparable<javax.measure.UnitConverter>
