Pro.ObservableMutable

trait ObservableMutable[A] extends Pro.O[A] with Pro.M[A]

Read/write/listenTo Property`

The usual implementation looks like:

class Foo:
  val namePro          : Pro.OM[String] = String.Pro.OM("")
  def name            : String         = namePro()
  def name_=(v:String): Unit           = namePro() = v
  val barPro           : Int.Pro.OM     = Int.Pro.OM(0)
  def bar             : Int            = valuePro()
  def bar_=(v:Int)    : Unit           = valuePro() = v

Def

Get value

Returns property value

   val pro: Pro.M[String] = Pro.M[String]("abc")

   val v1 = pro.apply() // Regular call
   val v2 = pro()       // Scala "syntactic sugar" call

On change subscription

Adds given function as listener to property change events

   val pro = String.Pro.OM("foo")

   // event subscription
   pro.onChange(() => "Change Detected".tp)

   // library based event subscription
   pro.onValueChangeWithOld((v, old) => "Value changed from " + old + " to " + v tp()))

   pro() = "bar"

   // Output
   Value changed from foo to bar
   Change Detected

Updates value

Updates property value

   val pro: Pro.M[String] = Pro.M[String]("")

   pro.update("abc") // Regular call

   pro() = "abc"     // Scala "syntactic sugar" call
