8. Measurement Package • Namespace: org.osgi.util.measurement • SI only Unit API “in the closet” • Unit Essentially an SI singleton holding relevant unit constants, too. • Measurement Represents a value with an error, a unit and a time-stamp. • State Groups a state name, value and timestamp. • Some usage, e.g. by Automotive ► no further development by OSGi OSGi 8 © 2007-2013 Creative Arts & Technologies

9. • Namespace: javax.microediton.sensor* • Focusing on Sensors, but it got a minimalistic Unit API “in the closet” • Unit Essentially an SI singleton holding relevant unit constants, too. JavaDoc: http://pandora.la/java/javadocs/sensor/javax/microedition/sensor/Unit.html • ChannelInfo Holding name, accuracy, data type,measurement ranges, scale and unit • MeasurementRange Range of possible values from minimum to maximum ► Dead Meat (few actual handsets and no vendors except Nokia still use it, nor does Java ME Embedded) JSR-256 9 © 2007-2013 Creative Arts & Technologies Mobile Sensor API

10. • Namespace: javax.measure.* • Only one interface and one abstract class • public interface Measurable<Q extends Quantity> • public abstract class Measure<V, Q extends Quantity> • Three sub-packages • quantity (holds dimensions mass, length) • unit (holds the SI and NonSI units) • converter (holds unit converters) JSR-275 10 © 2007-2013 Creative Arts & Technologies Units Specification

11. • JScience • Groovy/Grails • DSLs e.g. for Healthcare • GeoAPI (OGC standard) and implementations, e.g. • uDig (see http://locationtech.org/projects/technology.udig) •Parfait • Java Monitoring, part of Performance Co-Pilot (PCP) •… JSR-275 11 © 2007-2013 Creative Arts & Technologies Users and popular Downstream Projects

12. • Namespace: org.unitsofmeasurement.* • Only interfaces (and exception classes) • public interface Quantity<Q extends Quantity<Q>> • public interface Unit<Q extends Quantity<Q>> • Three sub-packages • quantity (holds dimensions mass, length,...) • unit (holds units) • service (holds services) The King is Dead… 12 © 2007-2013 Creative Arts & Technologies Units of Measurement API Walking

13. Units Framework for Eclipse and OSGi • Namespace: org.eclipse.uomo.* • Two main areas • Static Type Safe Units of Measure Support • Based on Units of Measurement API • On top of ICU4J, the Globalization standard at Eclipse and others (Android, GWT, Google Financial, etc.) • Prime UCUM Implementation • Successor to Eclipse OHF UCUM Bundle Eclipse UOMo 13 © 2007-2013 Creative Arts & Technologies

14. DEMO UOMo Examples

15. • Namespace: javax.measure.* • Only Interfaces and Base Exceptions • public interface Dimension • public interface Measurement<Q extends Quantity<Q>, V> • public interface Quantity<Q extends Quantity<Q>> extends Measurement<Q, Number> • public interface Unit<Q extends Quantity<Q>> • A “functional” Sub-package • function (contains functional interfaces, especially for Java 8 Lambdas) JSR-363 15 © 2007-2014 Creative Arts & Technologies Units of Measurement API (1.0)

16. • All other packages are OPTIONAL • format (contains Formatters und Parser) • quantity (contains dimensions like Mass, Length,...) • service (contains Services) JSR-363 16 © 2007-2014 Creative Arts & Technologies Units of Measurement API (1.0)
