Constructor Detail

PowersOfIntConverter

protected PowersOfIntConverter(int base,
                               int exponent)

Method Detail

of

public static PowersOfIntConverter of(Prefix prefix)

Creates a converter with the specified Prefix.

Parameters:

prefix - the prefix for the factor.

of

public static PowersOfIntConverter of(int base,
                                      int exponent)

Creates a converter with a factor represented by specified base^exponent.

Parameters:

base -

exponent -

Returns:

getBase

public int getBase()

getExponent

public int getExponent()

isIdentity

public boolean isIdentity()

isLinear

public boolean isLinear()

isSimpleCompositionWith

protected boolean isSimpleCompositionWith(AbstractConverter that)

Description copied from class: AbstractConverter

Non-API Guard for AbstractConverter.simpleCompose(AbstractConverter)

Specified by:

isSimpleCompositionWith in class AbstractConverter

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

Returns:

a new AbstractConverter that adds no additional conversion step

inverseWhenNotIdentity

public AbstractConverter 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

protected java.lang.Number convertWhenNotIdentity(java.math.BigInteger value,
                                                  java.math.MathContext ctx)

Description copied from class: AbstractConverter

Non-API

Overrides:

convertWhenNotIdentity in class AbstractConverter

Returns:

transformed value (most likely a BigInteger or BigDecimal)

convertWhenNotIdentity

public java.math.BigDecimal convertWhenNotIdentity(java.math.BigDecimal value,
                                                   java.math.MathContext ctx)
                                            throws java.lang.ArithmeticException

Description copied from class: AbstractConverter

Non-API

Specified by:

convertWhenNotIdentity in class AbstractConverter

Returns:

transformed value

Throws:

java.lang.ArithmeticException

convertWhenNotIdentity

public double convertWhenNotIdentity(double value)

Description copied from class: AbstractConverter

Non-API

Specified by:

convertWhenNotIdentity in class AbstractConverter

Returns:

transformed value

equals

public boolean equals(java.lang.Object obj)

Specified by:

equals in class AbstractConverter

transformationLiteral

public final java.lang.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:

compareTo

public int compareTo(javax.measure.UnitConverter o)

hashCode

public int hashCode()

Specified by:

hashCode in class AbstractConverter

composeSameBaseNonIdentity
