Re: [Gems-users] Using Ruby parameters on SLICC code? -- Repeated question, ignore

Hi Enrique,

 

I think you can define an action with two actual actions in it. And select different action according to your parameter. Because in a transition if you want to select different actions you might need to modify SLICC class.

 

Good luck!

Sorry to repeat the question that has been just sent!!

       This has been just asked last Sunday on the list, but the google
search didn't return any result as it hasn't already crawled the page.

Asunto: [Gems-users] Using Ruby parameters on SLICC code?

Dear list,

       I was wondering if it is possible to customize the protocol
behaviour depending on the values of Ruby parameters. This is, for example,
to define an action that would be different depending on the parameter that
was specified at execution time:

If (RubyParameter1){
       Do action a
}else{
       Take a different action
}

Obviously, this is simple to implement with two different SLICC protocols,
but I would like to know if it can be implemented in a single one, to
simplify and use parameters at execution time, and to avoid defining and
modifying the same file multiple times with minor changes.

I have tried, with no success, to use the Protocol options (like
TwoLevelCache or XactMemory) or RubyConfig options, but they are not
recognized when the slicc code is parsed. I have seen that parameters can be
used, quoted, to determine queues latencies, but this is a special case
which is considered in slicc\ast\EnqueueStatementAST.C. The only solution
that comes to my mind is to use methods in a given class defined outside
SLICC (such as TransactionManager) that directly return the value of the
given parameter (xact_mgr.getRubyParameter1(), etc), but that looks very
ugly.

Has somebody some experience on this? I haven't found any information on
previous messages on the list.

Thank you in advance,
