Abstract Value Members

  1. def extractGroup [T] (extractor: QueryExtractor[T], columnAlias: Map[String, String])(receiver: (T) ⇒ Unit): Unit

    Extract the rest of the rows remaining in this group of rows, using another extractor to build a collection of secondary result objects, typically from a 1-to-many JOIN, providing column aliasing from column name collisions, if needed.

  2. def extractOne [T] (extractor: JoinExtractor[T], aliasMap: Map[String, String]): Option[T]

    Leverage another extractor to extract secondary result object, typically from a 1-to-1 JOIN, providing column aliasing from column name collisions, if needed.
