public class TransformingComboBoxModel
implements javax.swing.ComboBoxModel

TransformingComboBoxModel is a model that is used for instances of javax.swing.JComboBox that can use transforms derived from com.sas.util.transforms.TransformInterface.

The TransformingListModel creates a new default model which is set to be a javax.swing.DefaultComboBoxModel to be used as the model for the comboBox. No default transform is set so no transformation will take place on the items in the list unless a transform is provided.
