So how would you like to describe these actions? Have them be invoked
without you coding an explicit function call to them?
What you can do is call a trampoline function, which does the action
first, and then calls your function. Something like this:
<map:match pattern="...">
<map:call function="doAction">
<map:parameter name="func" value="startFlow"/>
// Arguments for the 'startFlow' function if any should go here
</map:call>
</map:match>
In your script you'd then have something like:
function doAction(func, args)
{
// Do your action here
...
// Now call the function that executes the control flow
func.apply(this, args);
}
function startFlow(arg1, arg2, arg3 etc.)
{
// Do your flow here
}
To also have the actions executed when continuations are restarted,
I'll add the ability to specify a different function that handles
them. You'll then be able to specify your own continuation restarting
function (currently that's hard-coded to
handleContinuation). Something like this:
function myContinuationHandler(kont, args)
{
doAction(kont.continuation, args);
}
Is this the same thing you were looking for?
