Classes

Name Description
BadUnit This class is a convenience class that can be returned when a valid Unit cannot be determined.
BaseFormat A base Format class with shared properties and functionality between quantity and ecschema-metadata Format classes
BasicUnit This class provides basic implementation of UnitProps interface.
Format A class used to define the specifications for formatting quantity values.
Formatter A helper class that contains methods used to format quantity values based on a format that are defined via the Format class.
FormatterSpec A class that contains both formatting information and the conversion factors necessary to convert from an input unit to the units specified in the format.
Parser A Parser class that is used to break a string that represents a quantity value into tokens.
ParserSpec A ParserSpec holds information needed to parse a string into a quantity synchronously.
Quantity The Quantity class is convenient container to specify both the magnitude and unit of a quantity.
QuantityError The error type thrown by this module.

Interfaces

Name Description
AlternateUnitLabelsProvider This interface allows a provider to be specified that will define an array of alternate labels for a specific unit.
CloneOptions CloneOptions that define modifications that can be made during the cloning of a Format.
CloneUnit CloneFormat defines unit and label specification if primary unit is to be set during clone.
CustomFormatProps This interface is used when supporting Custom Formatters that need more than the standard set of properties.
FormatProps This interface defines the persistence format for describing the formatting of quantity values.
ParsedQuantity Successful result from Parser.parseToQuantityValue or Parser.parseToQuantityValue.
ParseQuantityError Parse error result from Parser.parseToQuantityValue or Parser.parseToQuantityValue.
PotentialParseUnit Interface that defines potential parse units that may be found in user's string input of a quantity value.
QuantityProps This interface defines the required properties of a Quantity.
UnitConversionProps This interface defines the properties required to convert a quantity value from one unit to another such as from meters to feet
UnitConversionSpec Interface that defines how to convert between a specific unit an another in synchronous formatting or parsing processing.
UnitProps This interface provides basic information about a Unit that is return from a UnitProvider.
UnitsProvider This interface is implemented by the class that is responsible for locating units by name or label and providing conversion values between units.

Type Aliases

Name Description
