Class com.datastax.driver.core.ResultSet

Examples of com.datastax.driver.core.ResultSet.all()

com.datastax.driver.core.ResultSet.all()
Returns all the remaining rows in this ResultSet as a list.
Note that, contrary to {@code iterator()} or successive calls to{@code one()}, this method forces fetching the full content of the ResultSet at once, holding it all in memory in particular. It is thus recommended to prefer iterations through {@code iterator()} when possible, especiallyif the ResultSet can be big. @return a list containing the remaining results of this ResultSet. Thereturned list is empty if and only the ResultSet is exhausted. The ResultSet will be exhausted after a call to this method.
