 49            functions inherited from the
 50            {@link CIMInstanceProvider CIMInstanceProvider} interface,

 57            <p>The Instance Query Provider receives operation requests from
 58            clients through calls to these functions by the CIM Server. Its
 59            purpose is to convert these to calls to system services,
 60            operations on system resources, or whatever platform-specific
 61            behavior is required to perform the operation modeled by
 62            the request. The specific requirements for each of the interface
 63            functions are discussed in their respective sections.</p>
