18.3.2.4 JmxMBeanAttrTableMetaImpl

JmxMBeanAttrTableMetaImpl extends the generated JmxMBeanAttrTableMeta class, and overrides the following methods.

• getEntry(SnmpOid rowOid), so that it returns an JmxMBeanAttrEntryImpl object for the indicated row.

• contains(SnmpOid oid, Object userData), so that it tells whether the indicated row is present int the table.

• getNextOid(Object userData), so that it returns the row index, the rowOid, of the first row in the table.

• getNextOid(SnmpOid rowOid,Object userData), so that it returns the index of the row that immediately follows the indicated row in the table.

The methods createNewEntry(SnmpMibSubRequest req, SnmpOid rowOid, int depth), and removeTableRow(SnmpMibSubRequest req, SnmpOid rowOid, int depth) are not overriden. The table is read-only, so these methods will never be called.

This class does not use any specific caching mechanism. Since the jmxMBeanAttrTable is an extension of the jmxMBeanTable it simply relies on the cache established for the jmxMBeanTable. The list of attributes pertaining to a specific MBean is cached, if necessary, in the corresponding JmxMBeanEntryImpl object, which can be reclaimed at the end of the request. Note that attribute values are not cached, but rather they are obtained when they are needed.
