Invoking an Object Service
Volt MX provides programmatic access to the backend data through Online Object Services. You must perform the following steps to gain the access:
-
Acquire a current instance of your object service.
-
Use the object service instance with data transfer objects to communicate as needed with your backend.
To acquire a current instance of your object service, refer to getObjectService Method documentation.
To know more about the methods that act on the Volt MX Foundry endpoint directly, refer to OnlineObjectService Class documentation.
