Method Details

observeSelect

public io.reactivex.rxjava3.core.Flowable<org.aksw.jenax.arq.util.binding.ResultTable> observeSelect(org.apache.jena.query.Query query)

Description copied from interface: RdfDataSourceObservable

Returns a flowable for the result table of the given query. The flowable is idle until subscription. Upon subscription either the query is executed or if there is a cached value from a prior execution then this one will be re-emitted. To re-execute a query it needs to be refreshed e.g. via #refreshAll(). If no change is detected after a refresh then no additional event should be sent.

Specified by:
