Class OneArgFuncAdapter

java.lang.Object
  |
  +--org.erights.e.elib.ref.OneArgFuncAdapter

All Implemented Interfaces:

OneArgFunc

public class OneArgFuncAdapter

extends Object

implements OneArgFunc

Untamed: Sends a message to target containing a cheap 1-argument function as argument. When this function is called it calls a method on the reactor with its argument. It's like the following E code:

     def OneArgFuncAdapter adapt(target, whenVerb, reactor, onVerb) {
         def adapter(arg) {
             E sendOnly(reactor, onVerb, [arg]);
         }
         E sendOnly(target, whenVerb, [adapter])
     }
 

Note that the on method (the method named by the onVerb) will be invoked after an additional send.
