org.tbee.swing.table
Class TableModelValueWrapper

java.lang.Object
  org.tbee.swing.table.TableModelValueWrapper

All Implemented Interfaces:: TableModel, TableModelForEdit

public class TableModelValueWrapper
extends Object
implements TableModelForEdit
extends Object
implements TableModelForEdit

This class adds ValueWrapper support to a TableModel. The reason behind this is that there are situations where you want to work with describing objects. For example a JComboBox could want the following behaviour: - the actual value stored could be an integer - but the displayed value should be a text If Integer were not a final class, one could extend that class and add a description plus change the toString method. But alas, Integer is final. So the actual value needs to be wrapped in a class that adds the description. However the model's getValueAt and setValueAt want Integers and not the wrapping classes, so somewhere there has to be a conversion from and to the wrapper. In order to achief this, setValueAt and getValueAt in this class have been extended: - if setValueAt encounters (an instance of) the ValueWrapper, it will continue with the contained value. - if getValueAt gets the value for a column that has a ValueWrapperFactory set, it will wrap the value. (The factory is registered for a column via the setValueWrapper method.) In the JComboBox example, the combobox will work completely with ValueWrapper objects and thus showing the description. This class will unwrap the ValueWrapper to the actual values. You may of course extend ValueWrapper and alter its behaviour (it could have been an interface).
