MonitorAdmin iPOJO Handler
--------------------------
This iPOJO handler alleviates the usage of the MonitorAdmin Service
(Specification OSGi R4 - Chapter 119: Monitor Admin Service Specification Version 1.0)


Examples of iPOJO metadata for the MonitorAdmin

* For Monitorable POJO

<monitoradmin:monitorable
   service:pid="java.lang.runtime"
>
   <monitoradmin:stateVariable
       field="m_memFree"
       monitoradmin:id="memory.free"
       monitoradmin:dynamic="true"/>

   <monitoradmin:stateVariable
       field="m_memMax"
       monitoradmin:id="memory.max"
       monitoradmin:dynamic="true"/>

   ...

</monitoradmin:monitorable>

The instrumented field m_memFree instrumenté doit être de type primitif (boolean, int, long, float, ...) ou java.lang.String

* For handler pour le monitoring job

<monitoradmin:monitoringJob
   field="m_monitoringstatusvar"
   callback="m_monitoringstatusvarReceived"
   monitoradmin:pid="java.lang.runtime/memory.free"
   monitoradmin:times="10000"
   monitoradmin:period="10"
   optional="false"
/> 

In the case of (optional="false"), if the state variable is not available, the POJO should be invalidated. However, events containing state variable values may be not already received.
