Glossary
callback
A procedure is called when an event occurs in an event-monitored environment (e.g. in
an X application). This procedure is called a callback function, or simply only callback.
class method
A class method is a method which is used on the class, rather than on an object. In C++
we also talk about static methods.
client
In a client/server system, a client makes requests/calls to a →server. It requests a
→service from the server. A client can also be the server of a client.
In addition to transaction-monitored clients, non-transaction-monitored clients, e.g.
X applications, can also be connected under T-ORB using T-ORB/Client.
client stub
In DCE terminology, a client stub is the same as a →stub under GINA.
commit
see →end of transaction
cursor
A cursor can be used to scroll through a list or set one element at a time. An important
special case is a database cursor, which is used to scroll through the result of a
database query.
customizing
This describes the feature which allows the user to carry out individual customizations.
The following mechanisms are available in the GINA environment:
→Persistency Service
In the persistency framework, the customizing concept allows you to embed external
classes from a class library as complete modules. Customizing to specific DBMS is also
possible; these special features offered can be exploited.
→T-ORB
The user-specific generation of the runtime environment in the T-ORB framework using
a special description language, whereby the description of the environment is trans-
formed accordingly using a generator.
