Field Detail

dimensionality	back to summary
private int dimensionality Determine the power of the `SingleUnit`. For example, for "square-meter", the dimensionality will be `2`. Note Default dimensionality is 1.

index	back to summary
private int index Simple unit index, unique for every simple unit, -1 for the dimensionless unit. This is an index into a string list in unit.txt {ConversionUnits}. The default value is -1, meaning the dimensionless unit: isDimensionless() will return true, until index is changed.

index

back to summary

private int index

Simple unit index, unique for every simple unit, -1 for the dimensionless unit. This is an index into a string list in unit.txt {ConversionUnits}.

The default value is -1, meaning the dimensionless unit: isDimensionless() will return true, until index is changed.

simpleUnitID	back to summary
private String simpleUnitID SimpleUnit is the simplest form of a Unit. For example, for "square-millimeter", the simple unit would be "meter"Ò The default value is "", meaning the dimensionless unit: isDimensionless() will return true, until index is changed.

simpleUnitID

back to summary

private String simpleUnitID

SimpleUnit is the simplest form of a Unit. For example, for "square-millimeter", the simple unit would be "meter"Ò

The default value is "", meaning the dimensionless unit: isDimensionless() will return true, until index is changed.

unitPrefix	back to summary
private MeasureUnit.MeasurePrefix unitPrefix SI or binary prefix.

public MeasureUnit build()

compareTo	back to summary
pack-priv int compareTo(SingleUnitImpl other) Compare this SingleUnitImpl to another SingleUnitImpl for the sake of sorting and coalescing. Sort order of units is specified by UTS #35 (https://unicode.org/reports/tr35/tr35-info.html#Unit_Identifier_Normalization). Takes the sign of dimensionality into account, but not the absolute value: per-meter is not considered the same as meter, but meter is considered the same as square-meter. The dimensionless unit generally does not get compared, but if it did, it would sort before other units by virtue of index being < 0 and dimensionality not being negative.

compareTo

back to summary

pack-priv int compareTo(SingleUnitImpl other)

Compare this SingleUnitImpl to another SingleUnitImpl for the sake of sorting and coalescing.

Sort order of units is specified by UTS #35 (https://unicode.org/reports/tr35/tr35-info.html#Unit_Identifier_Normalization).

Takes the sign of dimensionality into account, but not the absolute value: per-meter is not considered the same as meter, but meter is considered the same as square-meter.

The dimensionless unit generally does not get compared, but if it did, it would sort before other units by virtue of index being < 0 and dimensionality not being negative.

public SingleUnitImpl copy()

getDimensionality	back to summary
public int getDimensionality()

getIndex	back to summary
public int getIndex()

getNeutralIdentifier	back to summary
public String getNeutralIdentifier() Generates a neutral identifier string for a single unit which means we do not include the dimension signal.

getPrefix	back to summary
public MeasureUnit.MeasurePrefix getPrefix()

getSimpleUnitID	back to summary
public String getSimpleUnitID()

isCompatibleWith	back to summary
pack-priv boolean isCompatibleWith(SingleUnitImpl other) Checks whether this SingleUnitImpl is compatible with another for the purpose of coalescing. Units with the same base unit and SI or binary prefix should match, except that they must also have the same dimensionality sign, such that we don't merge numerator and denominator.

isCompatibleWith

pack-priv boolean isCompatibleWith(SingleUnitImpl other)

Checks whether this SingleUnitImpl is compatible with another for the purpose of coalescing.

Units with the same base unit and SI or binary prefix should match, except that they must also have the same dimensionality sign, such that we don't merge numerator and denominator.
