StreamMap<K, V> constructor
StreamMap<K, V> ({
- Map<
K, V> ? value, - OnUpdate<
Map< ? onUpdate,K, V> > - OnEvent<
CollectionEvent< ? onEvent,K, V> > - OnChange<
CollectionChangeEvent< ? onChange,K, V> >
StreamMap wraps a Map and adds functionality to each relevant method to notify any subscribed listeners of changes made to the map.
value
can be provided to return a StreamMap 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
StreamMap({
Map<K, V>? value,
OnUpdate<Map<K, V>>? onUpdate,
OnEvent<CollectionEvent<K, V>>? onEvent,
OnChange<CollectionChangeEvent<K, V>>? onChange,
}) : super(value ?? <K, V>{},
onUpdate: onUpdate, onEvent: onEvent, onChange: onChange);
