+/**
+ * This interface is provided to enable fine customization of the SNMP
+ * agent behaviour.
+ *
+ * <p>You will not need to implement this interface except if your agent
+ * needs extra customization requiring some contextual information.</p>
+ *
+ * <p>If an SnmpUserDataFactory is set on the SnmpAdaptorServer, then a new
+ * object containing user-data will be allocated through this factory
+ * for each incoming request. This object will be passed along to
+ * the SnmpMibAgent within SnmpMibRequest objects. By default, no
+ * SnmpUserDataFactory is set on the SnmpAdaptorServer, and the contextual
+ * object passed to SnmpMibAgent is null.</p>
+ *
+ * <p>You can use this feature to obtain on contextual information
+ * (such as community string etc...) or to implement a caching
+ * mechanism, or for whatever purpose might be required by your specific
+ * agent implementation.</p>
+ *
+ * <p>The sequence <code>allocateUserData() / releaseUserData()</code> can
+ * also be used to implement a caching mechanism:
+ * <ul>
+ * <li><code>allocateUserData()</code> could be used to allocate
+ *         some cache space,</li>
+ * <li>and <code>releaseUserData()</code> could be used to flush it.</li>
+ * </ul></p>
