Class EntityDataModel<T>

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Iterable<T>, javax.swing.table.TableModel
    public class EntityDataModel<T>
extends javax.swing.table.AbstractTableModel
implements javax.swing.table.TableModel, java.lang.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.
