Method Detail

findReferenceJoinForPredicateSwap

public static int findReferenceJoinForPredicateSwap(TableGroup tableGroup,
                                                    Predicate predicate)

Returns the index of a table reference join which can be swapped with the primary table reference to avoid rendering a real nested table group. REAL_TABLE_GROUP_REQUIRED is returned if swapping is not possible. #NO_TABLE_GROUP_REQUIRED is returned if no swapping is necessary.
