java.lang.Objectcom.sun.mdm.index.query.AssemblerEngineImpl
This AssemblerEngine is responsible to initialize the data structures that are used during Assembling. It holds reference to Array of QueryResultSet and call them in a loop until the next root composite object has been fetched and assembled. The actual assembling for each JDBC resultset is delegated to QueryResultSet.
