generating method names 'dynamically'

[Daniel Nogradi]

Is it possible to have method names of a class generated somehow dynamically?

More precisely, at the time of writing a program that contains a class
definition I don't know what the names of its callable methods should
be. I have entries stored in a database that are changing from time to
time and I always want to be able to call (from another program) those
method names which are at the moment present in the database.
