EntryExtractor Class Reference

Inherits AbstractExtractor, and PortableObject.

List of all members.

Detailed Description

The EntryExtractor is a base abstract class for special purpose custom ValueExtractor implementations.

It allows them to extract a desired value using all available information on the corresponding QueryMap.Entry object and is intended to be used in advanced custom scenarios, when application code needs to look at both key and value at the same time or can make some very specific assumptions regarding to the implementation details of the underlying Entry object.
