org.eclipse.jpt.common.utility.model.value
Interface TreeNodeValueModel<V>

Type Parameters:

V - the type of values held by the model

All Superinterfaces:

Model, ModifiablePropertyValueModel<V>, PropertyValueModel<V>

public interface TreeNodeValueModel<V>
extends ModifiablePropertyValueModel<V>

Extend ModifiablePropertyValueModel to better support org.eclipse.jpt.common.utility.internal.model.value.swing.TreeModelAdapter.

Implementors of this interface should fire a "state change" event whenever the node's internal state changes in a way that the tree listeners should be notified.

Implementors of this interface should also fire a "value property change" event whenever the node's value changes. Typically, only nodes that hold "primitive" data will fire this event.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
