Class AstMetrics

Namespace

LogicalOptimizer

Assembly

LogicalOptimizer.Core.dll

Size and shape metrics over expression trees. Cost model: an n-ary And/Or node counts as ONE node (and one operator) regardless of its operand count — the flat list is a single connective, not a chain of binary ones.
