RE: [Swarm-Support] Time efficiency of at$createActionTo$message

[Marshall, James A R]

Hi Marcus,
  sorry to be dense but what are the ObjectiveC style constructors in
Java... are those the interfaces/classes postfixed with S, C, SImpl, CImpl,
etc.?

For Java, especially with older builds of Swarm, it is important to 
avoid Objective C style constructors.  There's not only the overhead of 
the Objective C message dispatch but the indirection involved in 
associating Java's idea of the selector with the real selector.   
Instead, use
createFActionForEachHomogeneous$call.  This avoids all indirection for 
the callout to a Java method.   Randomization slowness as Paul notes 
will still apply, though.
