public class JavaBeanReader
extends ProxyReader

Obtains records from an object using bean introspection and reflection. See the Read from Java beans example.

JavaBeanReader's addField(String, String), addField(String, String, boolean), and addRecordBreak(String) methods use a subset of the XPath 1.0 location paths notation to identify field values and demarcate records.
