2 Changes since Version 3

2.1 Interface cancelations

The interfaces listed in the following section were changed in Version 4.0 of GINA. This ver-

sion contains the new variant. Each section indicates the GINA version as of which the rel-

evant interface or its old variant is no longer supported.

G_Exception eliminated

In earlier versions, GINA used the exception handling simulation of the Generic++ class

library [11] on some platforms. To facilitate this, the GINA exception classes were derived

internally from the Generic class G_Exception. This derivation process has had to be

eliminated because of a compiler problem.

The message and name methods derived from G_Exception described in the Reference

Manual are omitted from GINA Version 4.0 and later.

OQL

Version 3.0 of GINA sees the introduction of a new, improved interface for database queries

which is a subset of ODMG-OQL. Up to this version, the new OQL existed in parallel to the

old one and the user can decide the variant to be used.

Access via the old OQL will be eliminated as of GINA Version 4.0.

Entering special options in the mgen2 and mdiff generators

As of Version 3.3, special options (e.g. noansi, nohinfo) for the mgen2 and mdiff gen-

erators can be deﬁned in a ﬁle, i.e. you no longer need to specify them individually in the

call. Instead, you reference an existing ﬁle using the -k option when you call a generator.

All of the special options can be speciﬁed in this ﬁle.

As of Version 3.3, special options were supported both as call options and via a special op-

tion ﬁle. As of Version 4, however, special options will only be read from a ﬁle.
