| <p>It is possible to provide different implementations for the ConnectivityManager interface. At the moment there is one implementation available. |
| </p> |
| <a name="org.eclipse.smila.connectivity.impl"></a><h3> <span class="mw-headline">org.eclipse.smila.connectivity.impl</span></h3> |
| <p>This bundle contains the default implementation of the ConnectivityManager interface. |
| </p><p>The ConnectivityManagerImpl contains the core execution logic as it does the actual processing of the incoming requests. Incoming Record objects are split into different parts: |
| </p> |
| <ul><li> metadata (record attributes) is stored via the Blackboard Service in the RecordStorage |
| </li><li> attachments are stored via the Blackboard Service in the BinaryStorage |
| </li><li> a message object is added to a Queue containing the record Id and optional any additional metadata |
| </li></ul> |
| <p>This chart shows the Connectivity Manager implementation, it's Sub-Components and the relationship to other components: |
