Class SemanticExpressionEqualityComparer

Namespace

NextORM.Core

Assembly

nextorm.core.dll

Semantic equality comparer for expressions, distinct from the value-free plan comparer: literals compare by value, source parameters are alpha-equivalent, closure targets compare by reference identity plus member path, and unknown nodes are conservatively unequal. No captured value is evaluated.
