mutator

Method altering state

A mutator is something that causes mutation or change.

In programming, a mutator is a method that modifies an object's internal state—the counterpart to an accessor, which only reads it.

In genetics, a mutator gene increases the mutation rate of other genes.

The word appears almost exclusively in technical contexts.
