With the right load time semantics built into the JVM, one could presumably figure out the right access approach once (field or get method) and use it from thereon without further lookup overhead.
That aspect of the nebulous properties stuff (nebulous = oh, I meant events too and automatic event listeners and....) seems reasonably straightforward and helpful to add. In the mean time I use public final fields for "localized" value classes, i.e. those used in a fairly small scope. If the class is used broadly I tend towards getters and private fields to reduce the potential need for refactoring later. -- Jess Holle -- You received this message because you are subscribed to the Google Groups "The Java Posse" group.
