Example 3 with SnmpObjId

use of org.opennms.netmgt.snmp.SnmpObjId in project opennms by OpenNMS.

the class RequestPdu method send.

/*
     * This simulates send a packet and waiting for a response. 
     * 
     * This is a template method based on te getBulk algorithm. We use the getBulk
     * algorithm for get and nexts as well.  nonRepeaters for gets and nexts is always
     * equals to pdu size so there are no repeaters. maxRepitions is also always zero
     * for gets and nexts.
     * 
     * The method getRespObjIdFromReqObjId which by default goes 'next' is overridden
     * and does 'get' in the GetPdu.
