AbstractValueModelWrapper

public AbstractValueModelWrapper(ValueModel valueModel)

Method Detail

getValue

public Object getValue()

Description copied from interface: ValueModel

Returns this model's value. In case of a write-only value, implementers may choose to either reject this operation or or return null or any other appropriate value.

Specified by:

getValue in interface ValueModel

Returns:

this model's value

setValue

public final void setValue(Object value)

Description copied from interface: ValueModel

Sets a new value and if the value has changed notifies any registered value change listeners.

Specified by:

setValue in interface ValueModel

Parameters:

value - the value to be set

setValueSilently

public void setValueSilently(Object value,
                             PropertyChangeListener listenerToSkip)

Description copied from interface: ValueModel

Sets a new value and if the value has changed notifies all registered value change listeners except for the specified listener to skip.

Specified by:

setValueSilently in interface ValueModel

Parameters:

value - the value to be set

listenerToSkip - the PropertyChangeListener that should not be notified of this change (may be null).

getWrappedValueModel

public ValueModel getWrappedValueModel()

Description copied from interface: ValueModelWrapper

Returns the ValueModel wrapped by this ValueModelWrapper.

Specified by:

getWrappedValueModel in interface ValueModelWrapper

Returns:

the wrapped value model.

getInnerMostWrappedValueModel

public ValueModel getInnerMostWrappedValueModel()

Description copied from interface: ValueModelWrapper

Returns the inner most ValueModel wrapped by this ValueModelWrapper.

Specified by:

getInnerMostWrappedValueModel in interface ValueModelWrapper

Returns:

the inner most wrapped value model.

getInnerMostValue

public Object getInnerMostValue()

addValueChangeListener

public void addValueChangeListener(PropertyChangeListener listener)

Description copied from interface: ValueModel

Registers the given PropertyChangeListener with this ValueModel. The listener will be notified if the value has changed. The PropertyChangeEvents delivered to the listener must have the name set to "value". The latter ensures that all ValueModel implementers behave like the AbstractValueModel subclasses.

To comply with the above specification implementers can use the PropertyChangeSupport's #addPropertyChangeListener method that accepts a property name, so that listeners will be invoked only if that specific property has changed.

Specified by:

addValueChangeListener in interface ValueModel

Parameters:

listener - the listener to be added

AbstractValueModel.addValueChangeListener(PropertyChangeListener)

removeValueChangeListener

public void removeValueChangeListener(PropertyChangeListener listener)

Description copied from interface: ValueModel

Deregisters the given PropertyChangeListener from this ValueModel.

Specified by:

removeValueChangeListener in interface ValueModel

Parameters:

listener - the listener to be removed
