RowsetBase.FindByKey Method (Row, Func(Row, Boolean))

RowsetBase FindByKey Method (Row, Func Row, Boolean )

NFX Class Library

[This is preliminary documentation and is subject to change.]

Tries to find a row by specified keyset and extra WHERE clause and returns it or null if not found. This method does not perform well on Rowsets instances as a rowset is unordered list which does linear search. In contrast, Tables are always ordered and perform binary search instead
