public abstract class SetProperty extends Object implements ISetProperty
Constructor and Description |
---|
SetProperty() |
Modifier and Type | Method and Description |
---|---|
protected Set |
doGetSet(Object source)
Returns a Set with the current contents of the source's set property
|
protected void |
doSetSet(Object source,
Set set)
Updates the property on the source with the specified change.
|
protected void |
doUpdateSet(Object source,
SetDiff diff)
Updates the property on the source with the specified change.
|
Set |
getSet(Object source)
By default, this method returns
Collections.EMPTY_SET in
case the source object is null . |
IObservableSet |
observe(Object source)
Returns an observable set observing this set property on the given
property source
|
IObservableSet |
observeDetail(IObservableValue master)
Returns an observable set on the master observable's realm which tracks
this property of the current value of
master . |
IObservableFactory |
setFactory()
Returns a factory for creating observable sets tracking this property of
a particular property source.
|
IObservableFactory |
setFactory(Realm realm)
Returns a factory for creating observable sets in the given realm,
tracking this property of a particular property source.
|
void |
setSet(Object source,
Set set)
Updates the property on the source with the specified change.
|
void |
updateSet(Object source,
SetDiff diff)
Updates the property on the source with the specified change.
|
IMapProperty |
values(IValueProperty detailValues)
Returns the nested combination of this property and the specified detail
value property.

public Set getSet(Object source)
Collections.EMPTY_SET
in
case the source object is null
. Otherwise, this method
delegates to doGetSet(Object)
.
Clients may override this method if they e.g. want to return a specific
default set in case the source object is null
.

Note: This method is made available to facilitate basic property
access. However if the property source lacks property change
notification, then observables on the source object may not be notified
of the change. In most cases it is preferable to modify the source
through an IObservableSet
than through the property directly.
