RE: Java Style Question

["Richard Dettinger" <cujo@xxxxxxxxxx>]

Sure, but then you synchronize the setter/getter or put a trace statement
in that code and your problems are solved.  Otherwise you have to find the
212 different places that you referenced the 41 different internal instance
variables of the other object and you have to be careful to do it for
everything in your object hierarchy.

people.
It was true at Concord Bridge.  It was true at Pearl Harbor.  And it was
true today.

Richard,

Couldn't they just call the getter and setter to mess things up?

...But later, we start seeing heavily threaded applications,
applications
sharing transactions (via JTA support sitting on top of JDBC), etc.  So
we
synchronize everything in connection and synchronized everything in
statement to stop two threads from messing up a single object, but the
problem that remained was that threads doing stuff to the statement
are
'free' to modify the connection because they didn't call a method on
the
connection, they just changed what they wanted to.  This caused some
inconsistancies that were very hard to track down...
