class Dep[T, R] extends Reactive[T] with Stateful[T] with Mutable[T]

Dep allows creation of a dependent Var on another Var allowing conversion between the two. This can be useful for different representations of the same value. For example, in a graphical environment left, center, and right are all different representations of the value (horizontal position). Maintaining three distinct values while keeping them in-sync is painful. With Dep you can simply define one Var and two Dep values like:

val left: Var[Double] = Var(0.0) val width: Var[Double] = Var(0.0) val center: Dep[Double, Double] = Dep(left)(_ + (width / 2.0), _ - (width / 2.0)) val right: Dep[Double, Double] = Dep(left)(_ + width, _ - width)

Now, modification to left, center, or right will maintain the appropriate value for each without any additional boilerplate.

T

the type of value this Reactive receives

R

the type that this Dep receives
