Alternatives to InvokeMethod

[Ringo]

I've created a component that takes a class as an input
and executes methods on the class based on a set of text
instructions. The instructions are the names of the
methods to be executed and are different for each class
passed in. I've been using InvokeMethod to do this and it
works, but, it's TOO slow.

I've used the "eval" method in Jscript to do this sort of
thing and it doesn't seem to be as slow.

I'm about to try dynamic compilation but it seems quite a
bit more work (and is more likely to develop bugs).

I'd appreciate any ideas to solve this problem.

Thanks

If possible, the component, or the library containing the component, can
define an interface that must be implemented in the class passed to the
component. This requires select case blocks within the component to call the
appropriate method depending on the instructions, but I think it should be
faster than reflection.

Thanks, Armin

unfortunately, the objects can have any method name and
the component will only know which methods to call from a
text file. I can't recompile this component to add new
interfaces and the objects being passed to it will always
have there own set of methods.
