public class SpinnerListModel extends AbstractSpinnerModel implements Serializable
A simple implementation of SpinnerModel whose values are defined by an array or a List. For example to create a model defined by an array of the names of the days of the week:
String[] days = new DateFormatSymbols().getWeekdays(); SpinnerModel model = new SpinnerListModel(Arrays.asList(days).subList(1, 8));This class only stores a reference to the array or
List so if an element of the underlying sequence changes, it's up to the application to notify the ChangeListeners by calling fireStateChanged.
This model inherits a ChangeListener. The ChangeListeners are notified whenever the model's value or list properties changes.

listenerList public SpinnerListModel(List<?> values)
Constructs a SpinnerModel whose sequence of values is defined by the specified List. The initial value (current element) of the model will be values.get(0). If values is null or has zero size, an IllegalArugmentException is thrown.
values - the sequence this model representsIllegalArgumentException - if values is null or zero sizepublic SpinnerListModel(Object[] values)
Constructs a SpinnerModel whose sequence of values is defined by the specified array. The initial value of the model will be values[0]. If values is null or has zero length, an IllegalArgumentException is thrown.
values - the sequence this model representsIllegalArgumentException - if values is null or zero lengthpublic SpinnerListModel()
Constructs an effectively empty SpinnerListModel. The model's list will contain a single "empty" string element.
public List<?> getList()
Returns the List that defines the sequence for this model.
list propertysetList(java.util.List<?>)public void setList(List<?> list)
Changes the list that defines this sequence and resets the index of the models value to zero. Note that list is not copied, the model just stores a reference to it.
This method fires a ChangeEvent if list is not equal to the current list.
list - the sequence that this model representsIllegalArgumentException - if list is null or zero lengthgetList()public Object getValue()
Returns the current element of the sequence.
getValue in interface SpinnerModel
value propertySpinnerModel.getValue(), setValue(java.lang.Object)
public void setValue(Object elt)
Changes the current element of the sequence and notifies ChangeListeners. If the specified value is not equal to an element of the underlying sequence then an IllegalArgumentException is thrown. In the following example the setValue call would cause an exception to be thrown:
String[] values = {"one", "two", "free", "four"};
SpinnerModel model = new SpinnerListModel(values);
model.setValue("TWO"); setValue in interface SpinnerModel
elt - the sequence element that will be model's current valueIllegalArgumentException - if the specified value isn't allowedSpinnerModel.setValue(java.lang.Object), getValue()
public Object getNextValue()
Returns the next legal value of the underlying sequence or null if value is already the last element.
getNextValue in interface SpinnerModel
null if value is already the last elementSpinnerModel.getNextValue(), getPreviousValue()
public Object getPreviousValue()
Returns the previous element of the underlying sequence or null if value is already the first element.
getPreviousValue in interface SpinnerModel
null if value is already the first elementSpinnerModel.getPreviousValue(), getNextValue()
