All Implemented Interfaces:
AutoCloseable, org.aksw.commons.util.lifecycle.LifeCycle, SinkStreaming<org.apache.jena.sparql.engine.binding.Binding>, org.apache.jena.atlas.lib.Closeable, org.apache.jena.atlas.lib.Sink<org.apache.jena.sparql.engine.binding.Binding>
public class SinkStreamingBinding extends SinkStreamingBase<org.apache.jena.sparql.engine.binding.Binding>
A sink for writing out bindings as a result set using ResultSetMgr Internally uses a ResultSet that is backed by a Flowable<Binding>. Calling send(binding) publishes to that flowable and thus makes a new binding available in the result set. As the ResultSet blocks until items become available the ResultSetWriter runs in a another thread Uses a PublishSubject wrapped with ugly synchronization
