SnmpStandardObjectServer

public class SnmpStandardObjectServer extends Object implements Serializable

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 {@link com.sun.jmx.snmp.agent.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.

This API is a Sun Microsystems internal API and is subject to change without notice.

Fields Summary
Constructors Summary
Methods Summary
public voidcheck(SnmpStandardMetaServer meta, SnmpMibSubRequest req, int depth)
Generic handling of the check operation.

The default implementation of this method is to loop over the varbind list associated with the sub-request and to call check(var.value, var.oid.getOidArc(depth), data); 

public void check(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);
meta.check(var.value, id, data);
} catch(SnmpStatusException x) {
req.registerCheckException(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, or if you need to implement some consistency checks between the different values provided in the varbind list.

param
meta A pointer to the generated meta-data object which implements the SnmpStandardMetaServer interface.
