CIMType Qualifier
The CIMType qualifier contains text describing the type of a property.
This text can be the MOF type such as "string" and "sint32" or the CIM type such as "CIM_STRING" and "CIM_SINT32". There is a one-to-one correspondence between the CIMType qualifier and the type of the property used in the pvtType parameter of the IWbemClassObject::Get method.
The two exceptions are:
- Reference properties, which have the type CIM_REFERENCE, that contains the "REF:classname" value. The classname value describes the class type of the reference property.
- Embedded object properties, which have the CIM_OBJECT type.
Please note, however, that the CIMType qualifier can and should be used to type a reference property more exactly. For example, if the property always refers to instances of the Win32_LogicalDisk class, its CIMType qualifier should be set to:
"ref:Win32_LogicalDisk"
By default, the CIMType qualifier of a reference property has the type ref.
As with reference properties, the CIMType qualifier should used to type an embedded object property more exactly with the following syntax:
"object:EmbedClass"
Because WMI allows more types than can be expressed by standard constants with the VT_ prefix, the CIMType qualifier can help interpret type values. The CIMType qualifier is added automatically. For more information, see MOF Data Types.
