| EqualityComparer<TKey,TPayload,T>(IPropertySetter<TKey,TPayload>, Expression<Func<TPayload,T>>, IEqualityComparerExpression<T>) |
Sets a selected-substream equality comparer for the stream. Multiple of these can be set for various selectors. This comparer is an efficient comparer optimized for this data instance, and does not apply to other streams with the same schema. For a schema-level equality comparer, implement the interface IEqualityComparerExpression. |
| EqualityComparer<TKey,TPayload,T>(IPropertySetter<TKey,TPayload>, Expression<Func<TPayload,T>>, Expression<Func<T,T,Boolean>>, Expression<Func<T,Int32>>) |
Sets a selected-substream equality comparer for the stream. Multiple of these can be set for various selectors. This comparer is an efficient comparer optimized for this data instance, and does not apply to other streams with the same schema. |
