Method Detail

loadValue

public void loadValue()

Loads the component's database stored value.

Specified by:

loadValue in interface Presentable

destroy

public void destroy()

Description copied from interface: Markupable

Destroys the markupable. Useful to release e.g. static references which prevent the garbage collector from finalizing. For example HalfDataComboBoxes add s as Listeners to database changes. These listeners are registered statically. Thus, these listeners cannot be removed by the garbage collector, they have to be removed manually. This may be done by calling this destroy method.

Specified by:

destroy in interface Markupable

Overrides:

destroy in class MustReferencePresenter
