-------------------------------------------------
Hey [~bessbd]
So on your latest comment. I'm not sure where you would want the
StaticClass.init() function to be called from.
I tested the code and it looks like the static class will initiate when one of
the followings lines are hit for the first time.
replacementString = InetAddressCache.hostName;
replacementString = InetAddressCache.hostAddress;
replacementString = InetAddressCache.canonicalHostName;
The only place I would see to add the StaticClass.init would be at the init of
the parent class, but that will take the small hit of the one time lookup even
if the values are never used.
I'm personally in different. Just let me know where you would like the
StaticClass.init and let me know the value you are aiming to get from its
placement.
Thanks
