I find it peculiar to desire a 'final accessor'. After all,
class C {
int x;
final int getX() { return x; } <= what the heck is this
function for?
}
The only reason to have an accessor function is so it can be virtual.
I don't agree.
In any language with properties, accessors also allow for:
- lazy initialization
- changing the underlying data representation without requiring client
code to be rewritten
- implement access optimizations if the data is too costly to keep around
