org.eclipse.persistence.jpa.jpql.tools.resolver.DeclarationResolver
This {@link Resolver} is responsible to visit the current query (which is either the top-levelquery or a subquery) and gathers the information from the declaration clause. For a SELECT or DELETE clause, the information will be retrieved from the FROM clause. For an UDPATE clause, it will be retrieved from the unique identification range variable declaration. @version 2.5 @since 2.3 @author Pascal Filion
