How-to add row to a table?

This page describes how rows with SNMP values can be added to a SNMP4J-Agent table.

To add a row to a DefaultMOTable

1. Make sure that the MOTableModel used by the table is an instance of the MutableMOTableModel.

2. Create the row values as an array of Variable instances:

   Variable[] com2secValues = new Variable[] {
      new OctetString("public"),              // community name
      new OctetString("publicSecName"),       // security name
       getAgent().getContextEngineID(),        // local engine ID
      new OctetString(""),                    // default context name
      new OctetString(),                      // transport tag
      new Integer32(StorageType.nonVolatile), // storage type
      new Integer32(RowStatus.active)         // row status
   };
   

3. Let the SNMP4J-Agent API create a new row based on the provided values and the index sub-OID for the new row. The new will be created by the MOTableRowFactory assigned to MOMutableTableModel of the snmpCommunityTable. If the row factory is not set (for example to a DefaultMOFactory instance) then an exception will be thrown:

   MOTableRow newRow = snmpCommunityTable.createRow(new OctetString("public").toSubIndex(true), com2secValues); 

4. Add the newly created row to the table:

   ((MOMutableTableModel)snmpCommunityTable.getModel()).addRow(newRow);
