public abstract class AbstractDataTable
extends java.lang.Object
implements DataTable, Tableable

This abstract data table implementation provides some default implementations for data tables like listener handling. The method fireEvent() can be used to promote changes to all listeners. In addition, IO methods are also provided by this abstract implementation.
