close(completionHandler: Handler[AsyncResult[Unit]]): Unit
Like io.vertx.scala.sqlclient.Cursor#close but with a
completionHandlercalled when the cursor has been released. -
def
close(): Unit
Release the cursor.
Release the cursor.
It should be called for prepared queries executed with a fetch size.

def
closeFuture(): Future[Unit]
Like close but returns a scala.concurrent.Future instead of taking an AsyncResultHandler.
