Class AbstractSpinnerModel

java.lang.Object
javax.swing.AbstractSpinnerModel
All Implemented Interfaces:
Serializable, SpinnerModel
Direct Known Subclasses:
SpinnerDateModel, SpinnerListModel, SpinnerNumberModel
public abstract class AbstractSpinnerModel extends Object implements SpinnerModel, Serializable
This class provides the ChangeListener part of the SpinnerModel interface that should be suitable for most concrete SpinnerModel implementations. Subclasses must provide an implementation of the setValue, getValue, getNextValue and getPreviousValue methods.
Since:
1.4
