Class AbstractGridModel

java.lang.Object
  |
  +--net.sf.jeppers.grid.AbstractGridModel

All Implemented Interfaces:

GridModel

Direct Known Subclasses:

DefaultGridModel

public abstract class AbstractGridModel

extends Object

implements GridModel

This abstract class provides default implementations for most of the methods in the GridModel interface. It takes care of the management of listeners and provides some conveniences for generating GridModelEvents and dispatching them to the listeners. To create a concrete GridModel as a subclass of AbstractGridModel you need only provide implementations for the following three methods:

 public int getRowCount();
 public int getColumnCount();
 public Object getValueAt(int row, int column);
