PHP Units of Measure v2.0.0 Release Notes

Release Date: 2015-03-14 // about 9 years ago
    • Registered units of measure are now properties of PhysicalQuantity classes, and not individual instances of those classes. As such, registering a new unit with a given PhysicalQuantity will make that unit immediately available to all inntances of that class.
      • PhysicalQuantity classes no longer define their units in their constructor, and instead have a new initialize() static method
      • The previously-existing registerUnitOfMeasure() method on physical quantity objects has been replaced with a new static addUnit() method
      • The HasSoUnitsTrait method addMissingSIPrefixedUnits is now static
    • ➕ Added the toNativeUnit() method, to return values in their native unit of measure
    • ➕ Added the isEquivalentQuantity() method, to support future situations where it's not obvious whether two physical quantities represent the same quantity type
    • 👍 getSupportedUnits() is no longer available on physical quantities
    • The PhysicalQuantity parent class is now named AbstractPhysicalQuantity
    • ➕ Add a new DemonstrationTests test file, to demonstrate and test typical use cases
    • All library exceptions extend from AbstractPhysicalQuantityException, making catching easier
    • ➕ Added an interface for PhysicalQuantities, to support future work where not all physical quantity classes necessarily have the same parent
