public class WMIClient
extends QueryClient

WMIClient provides services for executing queries on WMI databases and the Windows registry. Use this class for protocols whose name is ClientsConsts.WMI_PROTOCOL_NAME
The working namespace to query can be redefined for WmiClient by setting the value of property AgentConstants.PROP_WMI_NAMESPACE. If not set, the default root\\cimv2 is used.
All Protocol properties can be redefined when creating the client.
Here is example of using WMIClient to work with the Windows registry:

 # The method that prepares client for query and calls getRegValues method for execution
 def DiscoveryMain(Framework):
    props = Properties()
    props.setProperty(AgentConstants.PROP_WMI_NAMESPACE, 'root\\DEFAULT')
    wmiClient = Framework.getClientFactory().createClient(props)
    keypath = 'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall'
    filter = 'DisplayName'
    names = getRegValues(wmiClient, keypath, filter)

 # This method executes and processes the result
 def getRegValues(wmiClient, keypath, filter):
     result = {}
     table = wmiClient.getRegistryKeyValues(keypath, 1, filter)
     keys = table.get(0)
     values = table.get(1)
     for i in range(keys.size()):
         key = keys.get(i)
         end = key.find('\\' + filter)
         key = key[0:end]
         result.update({key : values.get(i)})
     return result
