[news.eclipse.modeling.m2m] Re: [QVTO] Transformation performance degrad

[alex.leites@xxxxxxxxx (Alex )]

I have edited the original message on the forums adding the code 
demonstrating the issues, but it looks like edits are not propageted to 
the newsgroups, so here it is again:

import emf.tools;
modeltype Ecore "strict" uses 'http://www.eclipse.org/emf/2002/Ecore';

transformation test(out model : Ecore);

main() {
	var start := this.currentTimeMillis();
	var i:= 0, s := this.currentTimeMillis();
	while(i<20000) {
		i := i + 1;
		i.map ToClass();
		if i.mod(2000)=0 then {
			log('Last 2000 took ' + (this.currentTimeMillis()-s).toString() + ' 
ms');
			s := this.currentTimeMillis();
		} endif;
	};
	log('Total: ' + (this.currentTimeMillis()-start).toString() + ' ms');
}

mapping Integer::ToClass() : EClass
{
   name := 'c' + self.toString();
}
