[#372239] best practice for redefining methods at runtime? — Chuck Remes <cremes.devlist@...>
I have a class that I would like to "freeze" when it reaches a particular state so that it becomes read-only. I do *not* want to use the existing #freeze method because it raises an exception when there is an attempted mutation on a frozen object and I want the attempt to be silent. It appears that the best way to enforce this (state machine pattern) is by redefining the accessors and other methods that cause mutations to be no ops.

Some questions with my guesses at possible answers: How much data is carried for each individual? a few alleles? a lot? the whole human genome? What is done in the innermost loop? I imagine you select a pair of individuals, cross them, etc to produce more individuals. Or perhaps an individual dies or migrated to another population. What do you do to run a new experiment? generate the initial population, specify the rules for combination, depth, migration, etc? gather data and process it at the end? How much code do you need to write or rewrite for an experiment? How many parameters are involved? Can you give some examples of aspects of the C++ program that you hope to improve by moving the sim to Ruby? Can you say something about the context of your modeling? How is your simulator different from others used in the field? -- Bill
