bwmcadams / CallableMap.scala
Created January 26, 2011 21:34
Quick and dirty version of Map in Scala that can be 'called' like Python dicts where unknown methods are pulled out as Map keys. Uses the 2.9 dynamic trait.
class CallableMap extends scala.collection.mutable.HashMap[String, Any] with Dynamic {
def invokeDynamic(name: String)(args: Any*) = {
println("Invoke Dynamic: (name = %s)(args: %s)".format(name, args))
get(name)
}
def typed[T]: T = {
asInstanceOf[T]
}
