IWbemClassObject::CompareTo

[This is preliminary documentation and subject to change.]

The IWbemClassObject::CompareTo method compares an object to another CIMOM object. Note that there are certain constraints in this comparison process.

HRESULT IWbemClassObject::CompareTo(
  [in] Long lFlags, 
  [in] IWbemClassObject *pCompareTo
);
 

Parameters

lFlags

Specifies the object characteristics to consider in comparison to other object. It can be WBEM_COMPARISON_INCLUDE_ALL to consider all features, or any combination of these flags:

WBEM_FLAG_IGNORE_OBJECT_SOURCE

The source of the objects, namely the server and the namespace they came from, are ignored in comparison to other objects.

WBEM_FLAG_IGNORE_QUALIFIERS

All qualifiers (including "key" and "dynamic") should be ignored in comparison.

WBEM_FLAG_IGNORE_DEFAULT_VALUES

Default values of properties should be ignored. This flag is only meaningful when comparing classes.

WBEM_FLAG_IGNORE_FLAVOR

Ignore qualifier flavors. This flag still takes qualifier values into account, but ignores flavor distinctions such as propagation rules and override restrictions (see Qualifier Flavors).

WBEM_FLAG_IGNORE_CASE

Compares strings in a case-insensitive manner. This applies both to strings and to qualifier values. Property and qualifier names are always compared in a case-insensitive manner.

WBEM_FLAG_IGNORE_CLASS

This flag instructs the system to assume that the objects being compared are instances of the same class. Consequently, this flag compares instance-related information only. Use this flag to optimize performance. If the objects are not of the same class, the results are unpredictable, and probably are worthless.

pCompareTo

The object in comparison. This pointer must point to a valid IWbemClassObject instance. It cannot be NULL.
