Generic invocation of typeMethods

[gtcp]

Is there a way to call a static method using a class reference?

I want to grab a bunch of classes, store references, then pick one and invoke a type method on it. In essence this is something like cls : Class; begin cls := ClassA; …then much later… cls@methodName(); Of course this gives a syntax error because methodName is unknown on Class.

You might think sendTypeMsg would solve this but I seem to need to invoke it on an instance of a class, which defeats the purpose here.

Is there any way to do this?

Thanks so much, Kevin. Sure, it's a workaround but it works! Here's a minor bit of polish on that, just wrapping up the oid-wrangling into a method on Class cheekily called static:

Code: Select all

static() : Object; begin return (number.String & '.1').asOid(); end;

That tidies the invocation to cls.static().YourClass@yourMethod().
