The server uses connection classes at design time to support the creation and management of connection namespace nodes (as well as adapter service and notification namespace nodes). At run time, the ADK connection manager creates and releases connections as necessary, based on the pool configuration in the connection node and the demand for access to the adapter resource. This section describes the interactions of connection classes during the management of connection namespace nodes, as well as the basic flow used whenever connections are created or destroyed. The specifics of how these activities pertain to the interactions of adapter services and notifications are described later in this document.
