abstract class ResultSetInvoker[+R] extends Invoker[R]

An invoker which calls a function to retrieve a ResultSet. This can be used for reading information from a java.sql.DatabaseMetaData object which has many methods that return ResultSets.

For convenience, if the function returns null, this is treated like an empty ResultSet.
