getDelegate
public final IListProperty<S,E> getDelegate(S source)
Returns the property to delegate to for the specified source object. Repeated calls to this method with the same source object returns the same delegate instance.- Parameters:
source- the property source (may be null)- Returns:
- the property to delegate to for the specified source object.
-
doGetDelegate
protected abstract IListProperty<S,E> doGetDelegate(S source)
Returns the property to delegate to for the specified source object. Implementers must ensure that repeated calls to this method with the same source object returns the same delegate instance.- Parameters:
source- the property source- Returns:
- the property to delegate to for the specified source object.
-
getElementType
public Object getElementType()
Description copied from interface:IListPropertyReturns the type of the elements in the collection ornullif untyped- Returns:
- the type of the elements in the collection or
nullif untyped
-
doGetList
protected List<E> doGetList(S source)
Description copied from class:ListPropertyReturns a List with the current contents of the source's list property- Overrides:
doGetListin classListProperty<S,E>- Parameters:
source- the property source- Returns:
- a List with the current contents of the source's list property
-
doSetList
protected void doSetList(S source, List<E> list)
Description copied from class:ListPropertyUpdates the property on the source with the specified change.- Overrides:
doSetListin classListProperty<S,E>- Parameters:
source- the property sourcelist- the new list
-
doUpdateList
protected void doUpdateList(S source, ListDiff<E> diff)
Description copied from class:ListPropertyUpdates the property on the source with the specified change- Overrides:
doUpdateListin classListProperty<S,E>- Parameters:
source- the property sourcediff- a diff describing the change
-
observe
public IObservableList<E> observe(S source)
Description copied from interface:IListPropertyReturns an observable list observing this list property on the given property source- Specified by:
observein interfaceIListProperty<S,E>- Overrides:
