Package org.eclipse.core.databinding.property.list

Class SimpleListProperty<S,E>

java.lang.Object

org.eclipse.core.databinding.property.list.ListProperty<S,E>

org.eclipse.core.databinding.property.list.SimpleListProperty<S,E>

Type Parameters:

S - type of the source object

E - type of the elements in the list

All Implemented Interfaces:

IProperty, IListProperty<S,E>

Direct Known Subclasses:

ViewerListProperty, WidgetListProperty

public abstract class SimpleListProperty<S,E>
extends ListProperty<S,E>

Simplified abstract implementation of IListProperty. This class takes care of most of the functional requirements for an IListProperty implementation, leaving only the property-specific details to subclasses.

Subclasses must implement these methods:

• IListProperty.getElementType()
• doGetList(Object)
• doSetList(Object, List, ListDiff)
• adaptListener(ISimplePropertyListener)

In addition, we recommended overriding Object.toString() to return a description suitable for debugging purposes.

Since:

1.2

SimpleListProperty

public SimpleListProperty()

Method Details

observe

public IObservableList<E> observe(Realm realm,
 S source)

Description copied from interface: IListProperty

Returns an observable list observing this list property on the given property source

Parameters:

realm - the observable's realm

source - the property source

Returns:

an observable list observing this list property on the given property source

doGetList

protected abstract List<E> doGetList(S source)

Description copied from class: ListProperty

Returns a List with the current contents of the source's list property

Overrides:

doGetList in class ListProperty<S,E>

Parameters:

source - the property source

Returns:

a List with the current contents of the source's list property

setList

public final void setList(S source,
 List<E> list,
 ListDiff<E> diff)

Updates the property on the source with the specified change.

Parameters:

source - the property source

list - the new list

diff - a diff describing the change

Since:

1.6

Restriction:

This method is not intended to be referenced by clients.

doSetList

protected abstract void doSetList(S source,
 List<E> list,
 ListDiff<E> diff)

Updates the property on the source with the specified change.

Parameters:

source - the property source

list - the new list

diff - a diff describing the change

Restriction:

This method is not intended to be referenced by clients.

doSetList

protected void doSetList(S source,
 List<E> list)

Description copied from class: ListProperty

Updates the property on the source with the specified change.

Overrides:

doSetList in class ListProperty<S,E>

Parameters:

source - the property source

list - the new list

doUpdateList

protected void doUpdateList(S source,
 ListDiff<E> diff)

Description copied from class: ListProperty

Updates the property on the source with the specified change

Overrides:

doUpdateList in class ListProperty<S,E>

Parameters:

source - the property source

diff - a diff describing the change

adaptListener

public abstract INativePropertyListener<S> adaptListener(ISimplePropertyListener<S,ListDiff<E>> listener)

Returns a listener capable of adding or removing itself as a listener on a source object using the the source's "native" listener API. Events received from the source objects are parlayed to the specified listener argument.

This method returns null if the source object has no listener APIs for this property.

Parameters:

listener - the property listener to receive events

Returns:

a native listener which parlays property change events to the specified listener, or null if the source object has no listener APIs for this property.

Restriction:

This method is not intended to be referenced by clients.
