changes abstract method

Stream<QueryChange<ResultSet>> changes()

Returns a Stream to be notified of changes to the results of this query.

This is an alternative stream based API for the addChangeListener API.

AsyncListenStream

If the stream is missing changes, check if the returned stream is an AsyncListenStream. This type of stream needs to perform some async work to be fully listening. You can wait for that moment by awaiting AsyncListenStream.listening.

Implementation

Stream<QueryChange> changes();
