All Implemented Interfaces:

DataLookup

public class DefaultDataLookup
extends Object
implements DataLookup

Default implementation for DataLookup using reflection. This is how you would register a text field with a data model using this default implementation:

 DataModel dataModel;
 JTextField textField;
 ...
 Method method = null;
 try {
     method = textField.getClass().getMethod("getText", null);
 } catch (NoSuchMethodException nsme) {}
 DataLookup dataLookup = new DefaultDataLookup(textField, method, null);
 dataModel.registerDataLookup("MyTextField", dataLookup);
