| /** | |
| * OGNL stands for Object-Graph Navigation Language; it is an expression language | |
| * for getting and setting properties of Java objects. You use the same expression | |
| * for both getting and setting the value of a property. | |
| * | |
| * OGNL started out as a way to set up associations between UI | |
| * components and controllers using property names. As the desire for | |
| * more complicated associations grew, Drew Davidson created what he | |
| * called KVCL, for Key-Value Coding Language, egged on by Luke | |
| * Blanshard. Luke then reimplemented the language using ANTLR, came up | |
| * with the new name, and, egged on by Drew, filled it out to its current | |
| * state. | |
| * | |
| * We pronounce OGNL as a word, like the last syllables of a drunken | |
| * pronunciation of "orthogonal" or like "ogg-null". | |
