RE: [Rails-devel] Stock market revisited

[Erik V. <eri...@hc...>]

I absolutely agree.

StockChart now has a generic log method,
which is called by all move methods, and reads:

logMove(String companyName, StockPrice from, StockPrice to) {
	if (to == null || from == to) {
		System.out.println (companyName+" stays at
"+from.getName());
	} else {
		System.out.println (companyName+" moved from
"+from.getName()+" to "+to.getName());
	}
}
where System.out will later be changed to a log file handle.
