Constructor Details

Pair

public Pair(javax.measure.UnitConverter left,
 javax.measure.UnitConverter right)

Creates a pair converter resulting from the combined transformation of the specified converters.

Parameters:

left - the left converter, not null.

right - the right converter.

Throws:

IllegalArgumentException - if either the left or right converter are null

Method Details

isLinear

public boolean isLinear()

Specified by:

isLinear in interface javax.measure.UnitConverter

isIdentity

public boolean isIdentity()

Specified by:

isIdentity in interface javax.measure.UnitConverter

createConversionSteps

protected List<? extends javax.measure.UnitConverter> createConversionSteps()

inverseWhenNotIdentity

public AbstractConverter.Pair 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 Number convertWhenNotIdentity(BigInteger value,
 MathContext ctx)

Description copied from class: AbstractConverter

Non-API

Overrides:

convertWhenNotIdentity in class AbstractConverter

Parameters:

value -

ctx -

Returns:

transformed value (most likely a BigInteger or BigDecimal)

convertWhenNotIdentity

public BigDecimal convertWhenNotIdentity(BigDecimal value,
 MathContext ctx)

Description copied from class: AbstractConverter

Non-API

Specified by:

convertWhenNotIdentity in class AbstractConverter

Parameters:

value -

ctx -

Returns:

transformed value

equals

public boolean equals(Object obj)

Specified by:

equals in class AbstractConverter

hashCode

public int hashCode()

Specified by:

hashCode in class AbstractConverter

getLeft

public javax.measure.UnitConverter getLeft()

getRight

public javax.measure.UnitConverter getRight()

compareTo

public int compareTo(javax.measure.UnitConverter obj)

Specified by:

compareTo in interface Comparable<javax.measure.UnitConverter>

transformationLiteral

protected 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.

Specified by:

transformationLiteral in class AbstractConverter

Returns:

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
