2025-03-18Made some changes to improve RAM of OpenDC (#318)Dante Niewenhuis
2025-03-18Unit System v2 (#243)Alessio Leonardo Tomei
* Separated `Time` unit into `TimeDelta` and `TimeStamp` + small fixes Addition and subtruction between `Timestamp`s is not allowed, but any other `Unit` operation/comparison is. `TimeDelta`s can be added/subtructed to/form `Timestamp`s. Deserialization of `Timestamp`: - `Number` -> interpreted as millis from Epoch - `Instant` (string representation) -> converted to Timestamp - `Duration` (string representation) -> interpreted as duration since Epoch (warn msg is logged) Deserialization of `TimeDelta` is the same as `Time` was before, with the diference that when an `Instant` is converted to an timedelta since Epoch a warning message is logged. * Unit System v2 - Merged `BoundedPercentage` and `UnboundedPercentage` - Overrided all operation defined in `Unit` in all subclasses to avoid as much as possible value classes being boxed in bytecode. If units are used as generics (hence also functions defined in Unit<T>) they are boxed (as double would if used as generic). - All units companions now subclass `UnitId`, and can be used as keys (e.g `Map<UnitId, idk>`), while offering `max` `min` and `zero` methods. - Division between the same unit now returns `Percentage` - Added `Iterable<T>.averageOfUnitOrNull(selector (T) -> <specific unit>)` - `ifNeg0ThenPos0()` now is optional and not invoked on every constructor - Now methods in `Unit<T>` are all abstract, forcing override and avoid boxing in some cases - Added `@UnintendedOperation` and `UnitOperationException` for methods that must be defined but are not intended for use (e.g. `Timestamp` + `Timestamp`)
