        Description copied from class: Instruction
        All instructions that have thread-specific filenames or names encoded in it should overwrite this method in order to update (1) the in-memory instruction and (2) the instruction string
        Overrides:
        updateInstructionThreadID in class Instruction
        Parameters:
        pattern - ?
