JmxMBeanEntryImpl extends theJmxMBeanEntry skeleton that is generated by mibgen, and adds instrumentation to the entries of the jmxMBeanTable table defined in the MIB. Each JmxMBeanEntry represents an MBean registered in the exposed MBean server. The JmxMBeanEntry objects are created on the fly when needed. They are temporary objects which are created when an SNMP request needs access to the instrumented MBean. Once created, JmxMBeanEntry objects are put in the request-contextual cache, where they remain until the request completes.
