Studio Server plug-ins add (custom) functionality to Studio Server, for instance for connecting to external sources (such as a Web site or a database), or for automating specific processes.
Two types of Server plug-ins exist:
System plug-ins. Provide default Studio Server functionality.
Custom plug-ins. Any custom-made plug-in that is added to the default installation of Studio Server.
Each Server plug-in has its own feature and consists of one or more Connectors, each implementing a part of the feature. The plug-in acts as a container for these connectors, it describes their functionality and make it possible to activate or deactivate the feature.
Two types of connectors exist:
Service connectors can be used to interfere with the standard behavior of services offered by the application server. The “Overrule System” Run Mode make it possible for a connector to entirely implement a certain service, meaning that the standard service is not used at all. With the Before/After flavors, connectors can act before or after the system or manipulate information received from client applications or information that is about to leave the Server and sent to client applications.
The following types of Service connectors exist:
|Publish||Pub||Removed since Studio Server 10.12.0.|
The Run Mode defines the way and the events under which the connector is called by the Server. The following Run Modes exist:
- For connectors of type Service:
- Before System
- After System
- Before- and After System
- Overrule System
- For other connector types:
Connectors can be given a priority value which indicates the order in which the connector needs to be called. This is useful when there are multiple connectors implementing the same interface.
