Using data-provider model: SDN-R DB data-provider.
The data mapping moves the data from device specific model to the data-provider model.
Example: ietf harware component → data-provider Inventory
- ietf harware component: org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.hardware.rev180313.hardware.Component
- data-provider Inventory: org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.data.provider.rev190801.Inventory
The mapping needs to be implemented by code, that is hand-written or generated.
One possible implementation could be like this:
public class ORanToInternalDataModel {
public Inventory getInternalEquipment(NodeId nodeId, Component component) {
InventoryBuilder inventoryBuilder = new InventoryBuilder();
// General
inventoryBuilder.setNodeId(nodeId.getValue());
inventoryBuilder.setParentUuid(component.getParent());
inventoryBuilder.setTreeLevel(new Long(component.getParentRelPos()));
inventoryBuilder.setUuid(component.getUuid().getValue());
// -- String list with ids of holders
List<String> containerHolderKeyList = new ArrayList<>();
List<String> containerHolderList = component.getContainsChild();
if (containerHolderList != null) {
for (String containerHolder : containerHolderList) {
containerHolderKeyList.add(containerHolder);
}
}
inventoryBuilder.setContainedHolder(containerHolderKeyList);
// -- Manufacturer related things
inventoryBuilder.setManufacturerName(component.getName());
// Equipment type
inventoryBuilder.setDescription(component.getDescription());
inventoryBuilder.setModelIdentifier(component.getModelName());
inventoryBuilder.setPartTypeId(component.getXmlClass().getName());
inventoryBuilder.setTypeName(component.getName());
inventoryBuilder.setVersion(component.getHardwareRev());
// Equipment instance
inventoryBuilder.setDate(component.getMfgDate().getValue());
inventoryBuilder.setSerial(component.getSerialNum());
return inventoryBuilder.build();
}
