Examples of org.eclipse.persistence.queries.ComplexQueryResult

org.eclipse.persistence.queries.ComplexQueryResult

Purpose: Used to return multiple sets of information from a query. This is used if the objects and rows are required to be returned.

Responsibilities: Hold both the result of the query and the row results. @author James Sutherland @since TOPLink/Java 3.0
