Class _wmi_object

Attempt to pass attribute calls to the proxied COM object. If the attribute is recognised as a property, return its value; if it is recognised as a method, return a method wrapper which can then be called with parameters; otherwise pass the lookup on to the underlying object.

Use WMI's CompareTo_ to compare this object with another. Don't try to do anything if the other object is not a wmi object. It might be possible to compare this object's unique key with a string or something, but this doesn't seem to be universal enough to merit a special case.

Set several properties of the underlying object at one go. This is particularly useful in combination with the new () method below. However, an instance which has been spawned in this way won't have enough information to write pack, so only try if the instance has a path.

Return the WMI URI to this object. Can be used to determine the path relative to the parent namespace. eg,

<pre class="code"> pp0 = wmi.WMI ().Win32_ParallelPort ()[0] print pp0.path ().RelPath </pre>

Return a tuple representing the object derivation for
 this object, with the most specific object first. eg,

pp0 = wmi.WMI ().Win32_ParallelPort ()[0]
print ' <- '.join (pp0.derivation ())

Return a list of objects related to this one, optionally limited
     either by association class (ie the name of the class which relates
     them) or by result class (ie the name of the class which would be
     retrieved)

    <pre class="code">
c = wmi.WMI ()
pp = c.Win32_ParallelPort ()[0]

for i in pp.associators (wmi_association_class="Win32_PortResource"):
  print i

for i in pp.associators (wmi_result_class="Win32_PnPEntity"):
  print i
    </pre>
    

Return a list of associations involving this object, optionally
 limited by the result class (the name of the association class).

 NB Associations are treated specially; although WMI only returns
 the string corresponding to the instance of each associated object,
 this module will automatically convert that to the object itself.

<pre class="code">
c =  wmi.WMI ()
sp = c.Win32_SerialPort ()[0]

for i in sp.references ():
  print i

for i in sp.references (wmi_class="Win32_SerialPortSetting"):
  print i
</pre>
