functional programming - how to create receive {} block in scala with no arguments -

i want have nice code following in scala:

class myclass {     receive {       case dothis => println("dothis")       case dothat => println("dothat")     } } 

now understand receive should partial function, no matter partial function created didn't work. partial function should creating receive noarg code working.

or in other words code block should adding myclass can call

new myclass().receive(dothis) // code add myclass can call receive 

thanks

if want create partialfunction have specify type this:

sealed trait doparent case object dothis extends doparent case object dothat extends doparent  {   case dothis => println("dothis")   case dothat => println("dothat") }: partialfunction[doparent, unit] 

now can assign partial function (instance of partialfunction[doparent, unit]) variable or field this:

val receive: partialfunction[doparent, unit] = {   case dothis => println("dothis")   case dothat => println("dothat") }  receive(dothis) // dothis
