The objects of this class represent multiple conjunctive equalities in where conditions: =(f1,f2,...fn) <=> f1=f2 and f2= ... and =fn. The objects are used to generate new possibale paths to access the tables when executing a query. They are also used to optimize the execution plan chosen by the optimizer for the query.
