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 ornull
if untyped- Returns:
- the type of the elements in the collection or
null
if untyped
