public interface DataObject

The DataObject interface provides an extremely simple API for retrieving arbitrarily structured data. All "queries" are based simply on a selection string. It is entirely up to an implementation of this interface to define the syntax for these strings.

Method Summary

selectValue(RenderingContext context, java.lang.Object select) Given a select string, returns the value matching that selection.
