Welcome to the Extensible properties for Scala wiki!

This library provides typesafe and extensible properties for Scala projects. Encourages strong typing and provides jars providing support for various valid types of properties.

Currently, a default set of types: Int, Long, Float, Double, String, Boolean, Date, and Enumeration are supported by the core jar. The eprop-squants jar adds additional type support for the squants types: Mass, Energy, Density, etc. The eprop-joda jar adds additional type support for the joda types: DateTime, Instant, MutableDateTime, Seconds, Minutes, Hours, Days, Weeks, Months, and Years.

object ColorPType extends EKeyType[String]('color)
object LengthPType extends EKeyType[Double]('length)
object WidthPType extends EKeyType[Double]('width)

// declare your extensible model type
class Container(props: EProperty[_]*) extends Extensible {

  merge(Seq("blue" as ColorPType)) // a default
  merge(props)

  def color: Option[String] = get[String](ColorPType)
  def length: Option[Double] = get[Double](LengthPType)
  def width: Option[Double] = get[Double](WidthPType)
}

// now make an instance of your container with some values
val container = new Container(
  "red" as ColorPType, 20.0 as LengthPType, 23.3 as WidthPType)
assert(container.color == Some("red"))
assert(container.length == Some(20.0))
assert(container.width == Some(23.3))
