A val not a def, for speed, so that the calculation is done only once.
lazy, so that bodyParams can be changed by ValidatorCaller. Because this is a val, once this is accessed, either of the 3 params should not be changed, because the change will not be reflected. If you still want to change the the 3 params, after changing them, please also change this textParams.
