| javax.swing.SpinnerModel
All known Subclasses: javax.swing.AbstractSpinnerModel,
SpinnerModel | public interface SpinnerModel (Code) | | A model for a potentially unbounded sequence of object values. This model
is similar to ListModel however there are some important differences:
- The number of sequence elements isn't neccessarily bounded.
- The model doesn't support indexed random access to sequence elements.
Only three sequence values are accessible at a time: current, next and
previous.
- The current sequence element, can be set.
A SpinnerModel has three properties, only the first is read/write.
value
- The current element of the sequence.
nextValue
- The following element or null if
value is the
last element of the sequence.
previousValue
- The preceeding element or null if
value is the
first element of the sequence.
When the the value property changes,
ChangeListeners are notified. SpinnerModel may
choose to notify the ChangeListeners under other circumstances.

addChangeListener | void addChangeListener(ChangeListener l)(Code) | | Adds a ChangeListener to the model's listener list. The
ChangeListeners must be notified when models value
changes.
Parameters: l - the ChangeListener to add See Also: SpinnerModel.removeChangeListener |
getNextValue | Object getNextValue()(Code) | | Return the object in the sequence that comes after the object returned
by getValue() . If the end of the sequence has been reached
then return null. Calling this method does not effect value .
the next legal value or null if one doesn't exist See Also: SpinnerModel.getValue See Also: SpinnerModel.getPreviousValue |
getPreviousValue | Object getPreviousValue()(Code) | | Return the object in the sequence that comes before the object returned
by getValue() . If the end of the sequence has been reached then
return null. Calling this method does not effect value .
the previous legal value or null if one doesn't exist See Also: SpinnerModel.getValue See Also: SpinnerModel.getNextValue |
getValue | Object getValue()(Code) | | The current element of the sequence. This element is usually
displayed by the editor part of a JSpinner .
the current spinner value. See Also: SpinnerModel.setValue |
setValue | void setValue(Object value)(Code) | | Changes current value of the model, typically this value is displayed
by the editor part of a JSpinner .
If the SpinnerModel implementation doesn't support
the specified value then an IllegalArgumentException
is thrown. For example a SpinnerModel for numbers might
only support values that are integer multiples of ten. In
that case, model.setValue(new Number(11))
would throw an exception.
throws: IllegalArgumentException - if value isn't allowed See Also: SpinnerModel.getValue |
