Constructor Detail

UsmStatsMeta

public UsmStatsMeta(SnmpMib myMib,
                    SnmpStandardObjectServer objserv)

Constructor for the metadata associated to "UsmStats".

Method Detail

get

public SnmpValue get(long var,
                     Object data)
              throws SnmpStatusException

Get the value of a scalar variable

Specified by:

get in interface SnmpStandardMetaServer

Parameters:

var - OID arc of the queried scalar object.

data - A contextual object containing user-data. This object is allocated through the SnmpUserDataFactory for each incoming SNMP request.

Returns:

The SnmpValue of the scalar object identified by arc.

Throws:

SnmpStatusException - If the arc is not valid, or if access is denied.

set

public SnmpValue set(SnmpValue x,
                     long var,
                     Object data)
              throws SnmpStatusException

Set the value of a scalar variable

Specified by:

set in interface SnmpStandardMetaServer

Parameters:

x - New value for the scalar object identified by arc

var - OID arc of the scalar object whose value is set.

data - A contextual object containing user-data. This object is allocated through the SnmpUserDataFactory for each incoming SNMP request.

Returns:

The new SnmpValue of the scalar object identified by arc.

Throws:

SnmpStatusException - If the arc is not valid, or if access is denied.

check

public void check(SnmpValue x,
                  long var,
                  Object data)
           throws SnmpStatusException

Check the value of a scalar variable

Specified by:

check in interface SnmpStandardMetaServer

Parameters:

x - New value for the scalar object identified by arc

var - OID arc of the scalar object whose value is set.

data - A contextual object containing user-data. This object is allocated through the SnmpUserDataFactory for each incoming SNMP request.

Throws:

SnmpStatusException - If the arc is not valid, or if access is denied, or if the new desired value is not valid.

setInstance

protected void setInstance(UsmStatsMBean var)

Allow to bind the metadata description to a specific object.

get

public void get(SnmpMibSubRequest req,
                int depth)
         throws SnmpStatusException

Description copied from class: SnmpMibGroup

Generic handling of the get operation.

The actual implementation of this method will be generated by mibgen. Usually, this implementation only delegates the job to some other provided runtime class, which knows how to access the MBean. The current toolkit thus provides two implementations:

• The standard implementation will directly access the MBean through a java reference,
• The generic implementation will access the MBean through the MBean server.

Both implementations rely upon specific - and distinct, set of mibgen generated methods.

You can override this method if you need to implement some specific policies for minimizing the accesses made to some remote underlying resources.

Specified by:

get in class SnmpMibGroup

Parameters:

req - The sub-request that must be handled by this node.

depth - The depth reached in the OID tree.

Throws:

SnmpStatusException - An error occurred while accessing the MIB node.

set

public void set(SnmpMibSubRequest req,
                int depth)
         throws SnmpStatusException

Description copied from class: SnmpMibGroup

Generic handling of the set operation.

The actual implementation of this method will be generated by mibgen. Usually, this implementation only delegates the job to some other provided runtime class, which knows how to access the MBean. The current toolkit thus provides two implementations:

• The standard implementation will directly access the MBean through a java reference,
• The generic implementation will access the MBean through the MBean server.

Both implementations rely upon specific - and distinct, set of mibgen generated methods.

You can override this method if you need to implement some specific policies for minimizing the accesses made to some remote underlying resources.

Specified by:

set in class SnmpMibGroup

Parameters:

req - The sub-request that must be handled by this node.

depth - The depth reached in the OID tree.

Throws:

SnmpStatusException - An error occurred while accessing the MIB node.

check

public void check(SnmpMibSubRequest req,
                  int depth)
           throws SnmpStatusException

Description copied from class: SnmpMibGroup

Generic handling of the check operation.

• The standard implementation will directly access the MBean through a java reference,
• The generic implementation will access the MBean through the MBean server.

Both implementations rely upon specific - and distinct, set of mibgen generated methods.

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.

Specified by:

check in class SnmpMibGroup

Parameters:

req - The sub-request that must be handled by this node.

depth - The depth reached in the OID tree.

Throws:

SnmpStatusException - An error occurred while accessing the MIB node.

isVariable

public boolean isVariable(long arc)

Returns true if "arc" identifies a scalar object.

Specified by:

isVariable in class SnmpMibGroup

Parameters:

arc - An OID arc.

Returns:

true if `arc' leads to a variable.

isReadable

public boolean isReadable(long arc)

Returns true if "arc" identifies a readable scalar object.

Specified by:

isReadable in class SnmpMibGroup

Parameters:

arc - An OID arc.

Returns:

true if `arc' leads to a readable variable.

getAttributeName

public String getAttributeName(long id)
                        throws SnmpStatusException

Return the name of the attribute corresponding to the SNMP variable identified by "id".

Throws:

SnmpStatusException

isTable

public boolean isTable(long arc)

Returns true if "arc" identifies a table object.

Specified by:

isTable in class SnmpMibGroup

Parameters:

arc - An OID arc.

getTable

public SnmpMibTable getTable(long arc)

Returns the table object identified by "arc".

Specified by:

getTable in class SnmpMibGroup

Parameters:

arc - An OID arc.

Returns:

The SnmpMibTable identified by `arc', or null if `arc' does not identify any table.
