VIATRA/Releases/NewAndNoteworthy1.5
Support for more number literals in query language
All number literals supported by Xtend (see documentation for details) are now directly supported by the VIATRA Query language.
pattern circleConstantDiameter1(c : Circle) { Circle.diameter(c, 3l); Circle.area(c, 9.42f); }
Performance improvements in the incremental query evaluator (Rete engine)
Constant values (more precisely constant-value filtering) within patterns are now handled more efficiently in many cases. In a proprietary code base, specifically for entire query packages where this feature is heavily used, we have observed a reduction between 15-30% in the memory footprint of Rete.
