java.lang.Object

javax.swing.table.AbstractTableModel

jpa.tools.swing.EntityDataModel<T>

All Implemented Interfaces:

Serializable, Iterable<T>, TableModel

public class EntityDataModel<T>
extends AbstractTableModel
implements TableModel, Iterable<T>

A data model for a tabular view of a list of persistent entities. The data supplied by this model can be filtered to display field values of basic type or single-valued or multi-valued relationships.
The meta-information about the attributes of the entity are supplied by newly defined meta-model API of JPA 2.0 specification.
