java.lang.Objectcom.sun.management.snmp.agent.SnmpStandardObjectServer
public class SnmpStandardObjectServer
This class is a utility class that transform SNMP GET / SET requests into series of getAttributeName() setAttributeName() invoked on the MBean.
The transformation relies on the metadata information provided by the
SnmpStandardMetaServer
object which is
passed as first parameter to every method. This SnmpStandardMetaServer
object is usually a Metadata object generated by mibgen
.
The MBean is not invoked directly by this class but through the metadata object which holds a reference on it.
This class is used internally by mibgen generated metadata objects and you should never need to use it directly.

public void get(SnmpStandardMetaServer meta, SnmpMibSubRequest req, int depth) throws SnmpStatusException
get
operation.
The default implementation of this method is to loop over the
varbind list associated with the sub-request and to call
get(var.oid.getOidArc(depth), data);
public void get(SnmpStandardMetaServer meta, SnmpMibSubRequest req, int depth) throws SnmpStatusException { final Object data = req.getUserData(); for (Enumeration e= req.getElements(); e.hasMoreElements();) { final SnmpVarBind var= (SnmpVarBind) e.nextElement(); try { // This method will generate a SnmpStatusException // if `depth' is out of bounds. // final long id = var.oid.getOidArc(depth); var.value = meta.get(id, data); } catch(SnmpStatusException x) { req.registerGetException(var,x); } } }
You can override this method if you need to implement some specific policies for minimizing the accesses made to some remote underlying resources.

You can override this method if you need to implement some specific policies for minimizing the accesses made to some remote underlying resources, or if you need to implement some consistency checks between the different values provided in the varbind list.
