Creating a subnetwork with the API

Programmers documentation > Business objects and data sources > Subnetworks > Creating a subnetwork with the API

The following procedure creates the same subnetwork as in Loading a subnetwork defined in XML but through coding.

1. Create the subnetwork

IltNetworkElement subNetwork1 = new IltNetworkElement("SubNetwork1");

subNetwork1.setName("SubNetwork");

subNetwork1.setType(IltNetworkElement.Type.NMW);

2. Create the first child objects

List<IlpObject> children = new ArrayList<IlpObject>();

IltNetworkElement subNode1 = new IltNetworkElement("SubNode1");

subNode1.setName("BSC1");

subNode1.setType(IltNetworkElement.Type.BSC);

subNode1.setPosition(new IlpPoint(580, 80));

IltAlarmObjectState alarmState = new IltAlarmObjectState();

IltAlarm.State alarms = (IltAlarm.State)alarmState.getAlarmState();

alarms.setNewAlarmCount(IltAlarm.Severity.Warning, 2);

subNode1.setObjectState(alarmState);

children.add(subNode1);

3. Add the first child object to the subnetwork

datasource.setParent(subNode1, subNetwork1);

4. Create the second child object

IltNetworkElement subNode2 = new IltNetworkElement("SubNode2");

subNode2.setName("BTS2");

subNode2.setType(IltNetworkElement.Type.BTS_Image);

subNode2.setPosition(new IlpPoint(620, 180));

IltOSIObjectState osiState =

new IltOSIObjectState(new IltOSI.State(IltOSI.State.Operational.Enabled,

IltOSI.State.Usage.Active,

IltOSI.State.Administrative.ShuttingDown));

IltAlarm.State osiAlarms = (IltAlarm.State)osiState.getAlarmState();

osiAlarms.setNewAlarmCount(IltAlarm.Severity.Warning, 4);

osiState.set(IltOSI.Procedural.Reporting);

osiState.set(IltOSI.Repair.UnderRepair);

osiState.set(IltPerformance.SecState.Output, new Float(150));

subNode2.setObjectState(osiState);

children.add(subNode2);

5. Add the second child to the subnetwork

datasource.setParent(subNode2, subNetwork1);

6. Create an internal link

IltLink link = new IltLink("SubNode1-SubNode2");

link.setName("InternalLink");

link.setMedia(null);

link.setObjectState(new

IltBiSONETObjectState(IltSONET.State.ActiveProtecting,

null));

children.add(link);

7. Add the link to the subnetwork

datasource.setParent(link, subNetwork1);

8. Add the link relationship

datasource.setLink(link, subNode1, subNode2);

9. Add all the objects to the data source

datasource.addObject(subNetwork1);

datasource.addObjects(children);

NOTE For a subnetwork to be properly displayed, the parent object must be customized as a container node. Customization is achieved through CSS using the expansion property. For details, refer to Customizing subnetworks.
