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

`String`	`toString()`	Returns a string representation of the object.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis, int nanos)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Methods declared in interface SpinnerModel

getNextValue, getPreviousValue, getValue, setValue

Modifier and Type	Method	Description
`Object`	`getNextValue()`	Return the object in the sequence that comes after the object returned by `getValue()`.
`Object`	`getPreviousValue()`	Return the object in the sequence that comes before the object returned by `getValue()`.
`Object`	`getValue()`	The current element of the sequence.
`void`	`setValue(Object value)`	Changes current value of the model, typically this value is displayed by the `editor` part of a `JSpinner`.

Field Details

listenerList

protected EventListenerList listenerList

The list of ChangeListeners for this model. Subclasses may store their own listeners here.

Constructor Details

AbstractSpinnerModel

protected AbstractSpinnerModel()

Constructor for subclasses to call.

Method Details

addChangeListener

public void addChangeListener(ChangeListener l)

Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes.

Specified by:

addChangeListener in interface SpinnerModel

Parameters:

l - the ChangeListener to add

See Also:

removeChangeListener

public void removeChangeListener(ChangeListener l)

Removes a ChangeListener from the model's listener list.

Specified by:

removeChangeListener in interface SpinnerModel

Parameters:

l - the ChangeListener to remove

See Also:

getChangeListeners

public ChangeListener[] getChangeListeners()

Returns an array of all the ChangeListeners added to this AbstractSpinnerModel with addChangeListener().

Returns:: all of the ChangeListeners added or an empty array if no listeners have been added
Since:: 1.4

fireStateChanged

protected void fireStateChanged()

Run each ChangeListeners stateChanged() method.

See Also:

getListeners

public <T extends EventListener> T[] getListeners(Class<T> listenerType)

Return an array of all the listeners of the given type that were added to this model. For example to find all of the ChangeListeners added to this model:

myAbstractSpinnerModel.getListeners(ChangeListener.class);

Type Parameters:: T - the type of requested listeners
Parameters:: listenerType - the type of listeners to return, e.g. ChangeListener.class
Returns:: all of the objects receiving listenerType notifications from this model
