Method Detail

getDelegate

protected final ISetProperty<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 ISetProperty<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: ISetProperty

Returns the type of the elements in the collection or null if untyped

Returns:

the type of the elements in the collection or null if untyped

doGetSet

protected Set<E> doGetSet(S source)

Description copied from class: SetProperty

Returns a Set with the current contents of the source's set property

Overrides:

doGetSet in class SetProperty<S,E>

Parameters:

source - the property source

Returns:

a Set with the current contents of the source's set property

doSetSet

protected void doSetSet(S source,
                        Set<E> set)

Description copied from class: SetProperty

Updates the property on the source with the specified change.

Overrides:

doSetSet in class SetProperty<S,E>

Parameters:

source - the property source

set - the new set

doUpdateSet

protected void doUpdateSet(S source,
                           SetDiff<E> diff)

Description copied from class: SetProperty

Updates the property on the source with the specified change.

Overrides:

doUpdateSet in class SetProperty<S,E>

Parameters:

source - the property source

diff - a diff describing the change

observe

public IObservableSet<E> observe(S source)

Description copied from interface: ISetProperty

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

Specified by:

observe in interface ISetProperty<S,E>

Overrides:

observe in class SetProperty<S,E>

Parameters:

source - the property source

Returns:

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

observe

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

Description copied from interface: ISetProperty

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

Parameters:

realm - the observable's realm

source - the property source

Returns:

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