Loading a Subnetwork Defined in XML

This section shows how to load a subnetwork from an XML file in a data source. For detailed information about data sources, see section Data Sources.

All you have to do is create a data source using the data source default implementation defined by IltDefaultDataSource and pass the XML file to the parse method of the data source, as shown below:

dataSource = new IltDefaultDataSource();
dataSource.parse("SubnetworkXMLFile.xml");

Below is an example of a subnetwork defined in XML format. For details about the XML elements used in this example, see Table 3.1, Elements in an XML Data File.

The example creates a network element with identifier SubNetwork1. This network element is automatically interpreted by the network component as a subnetwork when you add the containment relationship using the XML tag <parent>.

The example creates a network element as a subnetwork that contains two children objects connected by a link.

How to Define a Subnetwork in an XML File

Add the subnetwork

<addObject id="SubNetwork1">

  <class>ilog.tgo.model.IltNetworkElement</class>

  <attribute name="name">SubNetwork</attribute>

  <attribute name="type">NMW</attribute>

</addObject>Add the subnetworks.

Add the child objects

<addObject id="SubNode1">

  <class>ilog.tgo.model.IltNetworkElement</class>

  <parent>SubNetwork1</parent>

  <attribute name="name">BSC1</attribute>

  <attribute name="type">BSC</attribute>

  <attribute name="position" javaClass="ilog.cpl.graphic.IlpPoint">

    <x>580</x>  <y>80</y>

  </attribute>

  <attribute name="objectState" javaClass="ilog.tgo.model.IltAlarmObjectState">

    <alarms>

      <new severity="Warning">2</new>

    </alarms>

  </attribute>

</addObject>

<addObject id="SubNode2">

  <class>ilog.tgo.model.IltNetworkElement</class>

  <parent>SubNetwork1</parent>

  <attribute name="name">BTS2</attribute>

  <attribute name="type">BTS_Image</attribute>

  <attribute name="position" javaClass="ilog.cpl.graphic.IlpPoint">

    <x>620</x>  <y>180</y>

  </attribute>

  <attribute name="objectState" javaClass="ilog.tgo.model.IltOSIObjectState">

    <state>

      <administrative>ShuttingDown</administrative>

      <operational>Enabled</operational>

      <usage>Active</usage>

    </state>

    <alarms>

      <new severity="Warning">4</new>

    </alarms>

    <procedural>Reporting</procedural>

    <repair>UnderRepair</repair>

    <performance state="Output">150</performance>

  </attribute>

</addObject>

Create a link connecting the two child objects

<addObject id="SubNode1-SubNode2">

  <class>ilog.tgo.model.IltLink</class>

  <parent>SubNetwork1</parent>

  <link>   <from>SubNode1</from>   <to>SubNode2</to>  </link>

  <attribute name="name">InternalLink</attribute>

  <attribute name="media">null</attribute>

  <attribute name="objectState" javaClass="ilog.tgo.model.IltBiSONETObjectState">

    <state>ActiveProtecting</state>

  </attribute>

</addObject>
