Interface IExpressionCacheKey

Namespace

LinqToDB.Internal.Linq

Assembly

linq2db.dll

Marks a value stored in a ConstantExpression as participating in the linq2db query cache key. Types implementing this interface are kept in the cached expression (not replaced with a ConstantPlaceholderExpression) so that distinct instances hash and compare by value via their own object.GetHashCode() and object.Equals(object) overrides.

public interface IExpressionCacheKey
