Siemens V 4.0 manual Callback, Class method, Client stub, Commit, Cursor, Customizing

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.
