Working With Proxies › Concepts and Definitions

Concepts and Definitions

A CA Gen Proxy is an interface that enables a user-written client application to communicate with a generated CA Gen server. Proxies make it possible for applications that are not generated using CA Gen, to use the procedure step logic provided as part of a Distributed Processing Server (DPS). In general, proxies provide application developers additional flexibility in creating multi-tier applications.

Proxies also make it possible for applications that are not generated using CA Gen, to access the interfaces and methods defined as components within a CBD-compliant model.

An application developer can create proxies of the following types:

• .NET Proxy
• Java Proxy
• Java Proxy (Classic Style)
• COM Proxy
• C Proxy

Apart from creating proxies that interface with the client code and the servers, you can also customize the proxy.

The following are the changes you can make on a proxy:

• Specify meaningful view names and attribute names.
• Use fewer attributes than defined in the model (views).
• Specify default values for omitted attributes.
• Pass default values as attributes.

  Such proxies are named Custom Proxies.

  Note: You cannot create custom proxies in Java (Classic Style) and C.

Note: For more information about customizing proxies, see the CA Gen Studio Overview Guide.
