StreamSet<E> constructor
StreamSet<E> ({
- Set<
E> ? value, - OnUpdate<
Set< ? onUpdate,E> > - OnEvent<
CollectionEvent< ? onEvent,int, E> > - OnChange<
CollectionChangeEvent< ? onChange,int, E> >
StreamSet wraps a Set and adds functionality to each relevant method to notify any subscribed listeners of changes made to the set.
value
can be provided to return a StreamSet that references
value
, if null
an empty list will be created instead. Note:
Modifications made to the map by referencing value
will not notify
the listeners of the changes made to it.
onUpdate
is a synchronous event called each time the collection
is modified and receives the entire collection as a parameter.
onEvent
is a synchronous event called each time the collection
is modified, and receives a list of all of the affected elements.
onChange
is a synchronous event called individually for every
element added, removed, or updated in the collection.
Implementation
StreamSet({
Set<E>? value,
OnUpdate<Set<E>>? onUpdate,
OnEvent<CollectionEvent<int, E>>? onEvent,
OnChange<CollectionChangeEvent<int, E>>? onChange,
}) : super(
value ?? <E>{},
onUpdate: onUpdate,
onEvent: onEvent,
onChange: onChange,
);
