Constructor Details

UsmDHParametersImpl

public UsmDHParametersImpl(org.snmp4j.smi.OID id,
 MOAccess access,
 org.snmp4j.smi.OctetString value)

Create a DHParameters instance that uses the Oakeley Group 1 Diffie Hellman parameters defined in RFC 2409 (see also DHGroups).

Parameters:

id - the instance OID of the scalar instance (last sub-identifier should be zero).

access - the maximum access level supported by this instance.

value - the initial value that defines the parameters as BER encoded OCTET STRING, see decodeBER(OctetString).

Method Details

getDHParamters

public org.snmp4j.security.dh.DHParameters getDHParamters()

encodeBER

public org.snmp4j.smi.OctetString encodeBER()

Encode this parameter set as BER octet string.

Returns:

the PKCS#3 encoded parameter octet string. If the encoding fails, null is returned.

decodeBER

public void decodeBER(org.snmp4j.smi.OctetString berValue)
               throws IOException

Throws:

IOException

getValue

public org.snmp4j.smi.OctetString getValue()

Description copied from class: MOScalar

Returns the actual value of this scalar managed object. For a basic instrumentation, overwrite this method to provide always the actual value and/or to update the internal value member and then call super.MOScalar.getValue() in the derived class.

Overrides:

getValue in class MOScalar<org.snmp4j.smi.OctetString>

Returns:

a non null Variable with the same syntax defined for this scalar object.

toString

public String toString()

Overrides:

toString in class MOScalar<org.snmp4j.smi.OctetString>
