9.7 Support for Language Native Iterators

All implementations of the DevAPI feature the methods shown in the UML diagram at the beginning of this chapter. All implementations allow result set iteration using fetchOne(), fetchAll() and nextResult(). In addition to the unified API drivers should implement language native iteration patterns. This applies to any type of data set (DocResult, RowResult, SqlResult) and to the list of items returned by fetchAll(). You can choose whether you want your X DevAPI-based application code to offer the same look and feel in all programming languages used or go for the natural style of a programming language.
