While the API (and possibly also RI/TCK, have to check with Martin) is already built by a Jenkins CI Server, this implementation is not part of the official JSR.

So we should look for another CI instance, potentially https://adopt-openjdk.ci.cloudbees.com/.

WDYT?

As Measurement no longer refers to numeric value or operations, these types are redundant and make no sense to the implementation:

• DoubleMeasurement
• FloatMeasurement
• IntegerMeasurement

Commit a1cfb64 seems to have deleted tec.uom.se.unit.US.java. Was this intended? Doesn't look to be related to the commit message?

Unlike OSGi Measurenent, we consider Quantity and Measurement as 2 separate entities.
Also see Martin Fowler's analysis: http://martinfowler.com/apsupp/apchap3.pdf
Measurement there contains Quantity rather than extending it.

So how about:
Measurement extends QuantitySupplier
with additional methods like getInstant() returning a java.time.Instant as "timestamp"

See https://java.net/jira/browse/UNITSOFMEASUREMENT-107

All time helper classes in tec.uom.se.quantity.time only refer too java.util.concurrent.TimeUnit, but none of them use java.time.temporal.TemporalUnit.

It does make sense to offer both, but there should be support for TemporalUnit, too.

While the SE implementation aims at SE/EE, it should still work on SE Embedded in the first place, meaning all 3 Java SE 8 profiles (including the smallest) should work. Otherwise this implementation could be subject to "profiling" and I'm not sure, if we want to add this complexity here;-)

Should run on a CI server with each profile or at least the minimal to ensure it works.

See https://java.net/jira/browse/UNITSOFMEASUREMENT-150

The 2 sets of message bundle properties in ../format and ../internal/format serve 2 different UnitFormat implementations. At least the locale-agnostic EBNFUnitFormat should not require more than one properties file. Translations where they don't exist there already should be moved to the one serving LocalUnitFormat. And strings for the default locale should be in sync between the two of them.

OutputHelper could be placed in the *se.internal.format package instead of util.

Add a parser for the ucum-essence.xml file

See https://java.net/jira/browse/UNITSOFMEASUREMENT-151

While this works fine against the RI the following statement (see tec.uom.demo.se.lambda.FunctionalDemo, last lines)
Quantity len = AbstractQuantity.of(10, SI.METRE);
Quantity len2 = len.to(US.FOOT);
System.out.println(len2);
won't work due to
Exception in thread "main" java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result.
at java.math.BigDecimal.divide(BigDecimal.java:1690)
at java.math.BigDecimal.divide(BigDecimal.java:1723)
at tec.uom.se.function.RationalConverter.convert(RationalConverter.java:117)
at tec.uom.se.IntegerQuantity.decimalValue(IntegerQuantity.java:56)
at tec.uom.se.AbstractQuantity.to(AbstractQuantity.java:162)
at tec.uom.demo.se.lambda.FunctionalDemo.main(FunctionalDemo.java:27)

Seems MathContext is wrongly applied here. Could be someting that changed with recent Java 8 builds, at least in Eclipse UOMo I haven't seen this and comparable classes also use BigDecimal there unlike the RI.

See https://java.net/jira/browse/UNITSOFMEASUREMENT-108

Aside from using JSR 308 there could be other means to enhance typing of mixed operations (divide/multiply) in Java SE.

Either passing an explicit type, which of course one must maintain for all possible operations, or via Lambdas, let's have a look at it here. Given the memory overhead of defining extra types for every possible operation, it is unlikely this makes sense for ME.

Should there be an outcome that is not a burden to ME, we could look into factoring some parts there later.

Some formatting showed errors, especially around KILO(GRAM) vs. KILOGRAM.
The version with prefix ended up with weird results like Gg instead of kg.

Based on earlier implementations this should be addressed and checked by JUnit tests.

Motivation:

One of Quantities that are used in Measure API is Time and is important that API works with the way that has in Java SE 8 or above. The proposal of this enhancement

Goal:

• Work with java.util.Date
• Work with new Java Date API (JSR 310)

Not Goal:

• With java.util.concurrent.TimeUnit or
• JavaFX Duration

Qualified:

• tec.uom.se.quantity, possibly
• tec.uom.se.unit or tec.uom.se.util

Taking over from this JIRA task
https://java.net/jira/browse/UNITSOFMEASUREMENT-103

CLDR is already used by JDK, and from Java 9 on (see http://openjdk.java.net/jeps/252) it should be the default. For Locale-sensitive classes like https://github.com/unitsofmeasurement/uom-se/blob/master/src/main/java/tec/uom/se/format/LocalUnitFormat.java (or a new CLDR-based variant) Unicode CLDR should be used wherever possible, too.

Add a new repository for the SE implementation

See https://java.net/jira/browse/UNITSOFMEASUREMENT-87

See https://java.net/jira/browse/UNITSOFMEASUREMENT-78

A new LongQuantity type derived from RI has some problems again with Java 8. Likely similar to what we saw with other types.

As modules https://github.com/unitsofmeasurement/uom-systems and https://github.com/unitsofmeasurement/si-units take the purpose, unit systems other than Units should be pruned like in the RI before.

Since Range or QuantityRange moved to implementations like this, an interesting approach by AirLift and its rudimentary unit-subsystem (only Duration and an equivalent to Information, see https://github.com/airlift/airlift/tree/master/units/src/main/java/io/airlift/units) is how they use BeanValidation together with their units.

If not a package within uom-se, due to the external dependency it may best qualify for a sub-module.

Problems with UCUM other than a straightforward UCUM parser similar to https://java.net/jira/browse/UNITSOFMEASUREMENT-114 also affect this implementation. It should either be fixed as soon as we can, or UCUM system and support also be removed from this implementation.

Range could be placed in the *se.spi package instead of util.

Similar to what JavaMoney does in many library repos, let's try to deploy Snapshot releases to Bintray/JFrog OSS repo

Similiar to the RI SimpleUnitFormat should be the (locale-neutral) default in most cases.
Only where a locale-sensitive UnitFormat is required for a particular format it may be explicitly used.

Otavio, please have a look at:
http://types.cs.washington.edu/checker-framework/current/checker-framework-manual.html#units-checks

You'll see, the JSR 308 Unit Checkers are "embryonal" stage at most compared to the full SI or UCUM support provided by JSR 363 and related APIs, but for that last bit of "MixedUnits" operations you may want to give it a try. Nobody even at Oracle (who was Co Spec Lead of this JSR) currently feels there is a real world use case for JSR 308 or uses it at the moment. So it can be considered "academic" or "experimental" at most. Feel free to try it out e.g. in a branch or fork of this project and see, if it even works beyond primitive types. No examples exist other than for int or double so far ;-/

This is an internal "helper parser" for UCUMFormat, it should be distinguishable from a more dedicated UCUMParser against an actual ucum-essense.xml file.

There's a bug in the SE port causing its build to fail.

[ERROR] Bundle tec.uom:uom-se:bundle:0.6-SNAPSHOT : Exception: 18
[ERROR] Bundle tec.uom:uom-se:bundle:0.6-SNAPSHOT : Invalid class file: tec/uom/se/function/QuantityFunctions.class

So far removed (disabled) the class and everything that depends on it. Please have a look,
We can't afford not to support OSGi especially on the SE side.

Regardless of the JDK 8 version (Update 20) the SE Implementation won't build with SE 8 due to compiler bugs like https://bugs.openjdk.java.net/browse/JDK-8035390

At least 100 issues remain, if they can't be fixed, given the target release in bugs like above is Java 9, we'd have to stick with Java 7 until this is resolved

[INFO] 100 errors

Also see https://java.net/jira/browse/UNITSOFMEASUREMENT-104

It looks like the internal impl detail exception may not easily be replaced by ParserException, but it may extend it and should have a different name like TokenException

Methods like the one fixed for #66 do not usually check for null.
The API does not specify whether
Number convert(Number value);
accepts null or not. Either we simply return null in such cases or throw an exception (must be in line with RI, too)

Proxy classes

We had a discussion about the classes that need to do proxy and about the consequence of these classes on lesser performance.

But still there are two classes:

• ProxyQuantityFactory
• OldProxyQuantityFactory

Is there any reason to these classes stay on uom-se ?

Quantities are currently not serializable (e.g. tec.uom.se.quantity.NumberQuantity; no valid constructor).
Assuming that either AbstractQuantity is missing a no-args constructor or interface Serializable.

Code to test:
public static void main(String[] args) throws IOException, ClassNotFoundException {
byte[] serialized = serialize(Quantities.getQuantity(0, Units.JOULE));
Object obj = deserialize(serialized);
ComparableQuantity quantity = (ComparableQuantity)obj;
}
public static Object deserialize(byte[] serialized) throws IOException, ClassNotFoundException {
ByteArrayInputStream bis = new ByteArrayInputStream(serialized);
ObjectInputStream ois = new ObjectInputStream(bis);
Object obj = ois.readObject();
ois.close();
return obj;
}
public static byte[] serialize(ComparableQuantity<?> quantity) throws IOException {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(quantity);
bos.close();
return bos.toByteArray();
}

The convenience method multiply(Quantity, Class) in ComparableQuantity does not work as expected.

This operation in NumberComparableQuantityTest.multiplyOperationsExceptionTest:
ComparableQuantity speed = metre.multiply(metre, Speed.class);
fails because the (WRONG!) operation won't throw a ClassCastException.

We won't get most CI servers with Java 9 till it's final (does anybody know if https://adopt-openjdk.ci.cloudbees.com/ allows adding OS projects like uom-se running on openjdk1.9 already?), but at least manually it would be good to do regular tests against Java 9, too: https://jdk9.java.net/download/

UOMo contains Indian prefixes like Crore or Lakh. Should also be included with the SE implementation.
