tech.units.indriya.function.AbstractConverter

tech.units.indriya.function.LogConverter

All Implemented Interfaces:

Serializable, Comparable<javax.measure.UnitConverter>, javax.measure.UnitConverter, tech.uom.lib.common.function.Converter<Number,Number>, tech.uom.lib.common.function.ValueSupplier<String>

public final class LogConverter
extends AbstractConverter
implements tech.uom.lib.common.function.ValueSupplier<String>

This class represents a logarithmic converter of limited precision. Such converter is typically used to create logarithmic unit. For example: Unit BEL = Unit.ONE.transform(new LogConverter(10).inverse());

Constructor Detail

LogConverter

public LogConverter(double base)

Returns a logarithmic converter having the specified base.

Parameters:

base - the logarithmic base (e.g. Math.E for the Natural Logarithm).

Method Detail

getBase

public double getBase()

Returns the logarithmic base of this converter.

Returns:

the logarithmic base (e.g. Math.E for the Natural Logarithm).

isIdentity

public boolean isIdentity()

Specified by:

isIdentity in interface javax.measure.UnitConverter

canReduceWith

protected boolean canReduceWith(AbstractConverter that)

Description copied from class: AbstractConverter

Non-API Guard for AbstractConverter.reduce(AbstractConverter)

Specified by:

canReduceWith in class AbstractConverter

Returns:

whether or not a composition with given that is possible, such that no additional conversion steps are required, with respect to the steps already in place by this converter

reduce

protected AbstractConverter reduce(AbstractConverter that)

Description copied from class: AbstractConverter

Non-API Guarded by AbstractConverter.canReduceWith(AbstractConverter)

Overrides:

reduce in class AbstractConverter

Returns:

a new AbstractConverter that adds no additional conversion steps, with respect to the steps already in place by this converter

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:

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.

Specified by:

transformationLiteral in class AbstractConverter

Returns:

equals

public boolean equals(Object obj)

Specified by:

equals in class AbstractConverter

hashCode

public int hashCode()

Specified by:

hashCode in class AbstractConverter

convertWhenNotIdentity

protected Number convertWhenNotIdentity(Number value)

Description copied from class: AbstractConverter

Non-API

Specified by:

convertWhenNotIdentity in class AbstractConverter

Returns:

transformed value

isLinear

public boolean isLinear()

Specified by:

isLinear in interface javax.measure.UnitConverter

getValue

public String getValue()

Specified by:

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

compareTo

public int compareTo(javax.measure.UnitConverter o)

Specified by:

compareTo in interface Comparable<javax.measure.UnitConverter>
