ognl: Object-Graph Navigation Language

Name:	ognl	Vendor:	JPackage Project
Version:	2.6.7	License:	BSD -style
Release:	1jpp	URL:	http://www.ognl.org/

Summary

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. The ognl.Ognl class contains convenience methods for evaluating OGNL expressions. You can do this in two stages, parsing an expression into an internal form and then using that internal form to either set or get the value of a property; or you can do it in a single stage, and get or set a property using the String form of the expression directly. Many people have asked exactly what OGNL is good for. Several of the uses to which OGNL has been applied are: * A binding language between GUI elements (textfield, combobox, etc.) to model objects. Transformations are made easier by OGNL's TypeConverter mechanism to convert values from one type to another (String to numeric types, for example). * A data source language to map between table columns and a TableModel. * A binding language between web components and the underlying model objects (WebOGNL, Tapestry and WebWork). * A more expressive replacement for the property-getting language used by the Jakarta Commons BeanUtils package (which only allows simple property navigation and rudimentary indexed properties). Most of what you can do in Java is possible in OGNL, plus other extras such as list projection and selection and lambda expressions.
