RE: Java Style Question

Richard,

I agree that performance is a non-issue and getters/setters
offer an opportunity to add your own hooks into a class.
I am wondering why a getter or setter for a class variable
changes the multi-threading issue. Most multi-threading issues
I have run into are fixed by passing them as parameters
and avoiding either direct access or access via getter/setter.

...2) Later you start multi-threading something that you never worried
about
threading issues for initiallly.  You start making various objects
safe
from the outside users and that is pretty easy, but you have all kinds
of
thread safety holes where two objects clobber each other's internal
state
from two threads that are allowed to execute at the same time...
