1 -Key-value coding is a way to separate interfaces and a way to flexibly access data and methods in object instances. The concept has a long history. It appeared in [[Eiffel>>http://en.wikipedia.org/wiki/Eiffel_(programming_language)]], and other places as well. If you are familiar with [[OGNL>>http://en.wikipedia.org/wiki/OGNL]] then you will know it from there. We'll call key-value coding KVC in the context of this page to abbreviate. KVC also exists in the Cocoa infrastructure shipped with MacOS-X, having evolved from OPENSTEP and the development tools created for it. In this page we will focus on KVC in the context of WebObjects and java.
