Talk:Agents in SCOOP

Revision as of 23:45, 20 March 2013 by Alexander Kogtenkov (Talk | contribs) (Asked for more details on usefulness of a target parameter.)

I use the first parameter in ROUTINE as a documentation hint, to specify the contract an agent is expected to fulfill.

That is, I declare the callback agent as having type ROUTINE [MY_CLASS, TUPLE [....]]

Then in MY_CLASS I declare a single deferred routine that conforms to the expected signature of the callback. This routine is then equipped with contracts.

This serves as a hint to the user as to what the requirements of the callback actually are. If the user follows the hint by inheriting from MY_CLASS to implement the call back, then the contract is actually checked at runtime, and so provides an early warning of what the bug is.

So I find it usefull.
