Standard WMI Qualifiers

Applies to: classes

Indicates that a class contains amended qualifiers that are localized. The default is TRUE.

The associated class can be translated. To access the translated version, use the locale identifier to construct a namespace name.

Applies to: methods

Indicates that the method call should pass directly to the ExecMethodAsync call of the provider rather than the provider first making a call to GetObject to validate the object path. The default is FALSE. Using Bypass_GetObject can significantly improve performance.

Before using Bypass_GetObject, ensure that neither of the following actions are taken:

• Derive a class from your class.
• Override the method that has the Bypass_GetObject qualifier.

Applies to: properties

Indicates that the associated property is a key property in CIM but not in WMI.

Applies to: properties, methods, parameters

Contains text describing the type of a property.

Applies to: classes

Indicates that a class has instances associated with more information dynamically supplied by a provider.

Applies to: properties, classes

Indicates the property has been superseded by another property.

Applies to: classes, properties

The UUID of the associated class.

Applies to: classes, properties

Indicates a class whose instances are created dynamically. The value of this qualifier must be set to TRUE.

Applies to: classes, instances

Indicates that an instance contains values provided by dynamic property providers. The default is TRUE.

You must specify this qualifier on such an instance. Only the value TRUE is allowed.

Applies to: instances

Indicates that the value of this property cannot change during the lifetime of the instance.

Applies to: properties, parameters

Uniquely identifies and sequences a property or method parameter when MOF statements are generated automatically.

This qualifier is required for method parameters only. When creating parameters for a method, class designers should begin with Id(0) for the first parameter and use each successive integer for each successive parameter. If the ID qualifiers are unintentionally omitted, the MOF compiler generates ID qualifiers automatically.

Applies to: methods

Indicates that a method has an implementation supplied by a provider.

Applies to: instances

Indicates that an instance contains values provided by a dynamic property provider.

The value is passed to the property provider as an argument to the IWbemPropertyProvider::GetProperty method.

Applies to: classes or instances

Specifies the language of origin for a class or instance. For more information about locale values, see Locale Codes.

Applies to: namespace instances

Specifies a security descriptor for the namespace in SDDL format. For more information, see Setting Namespace Security When the Namespace is Created. The SDDL string is processed by WMI to establish the namespace security but not stored as a string. If no security descriptor is specified, the default security is used. For more information, see Setting Namepace Security Descriptors.

Applies to: parameters

Indicates that a parameter is not required, and that it has a well-behaved default value.

Applies to: properties, methods

Set of values used to inform the client which privileges are required to create instances, fill in properties, or perform methods. The default is FALSE.

Applies to: properties

Indicates that an instance property contains values provided by dynamic property providers.

You must specify this qualifier on such a property. The value is passed to the property provider as an argument to IWbemPropertyProvider::GetProperty.

Applies to: classes

The value of this qualifier is the name of the dynamic provider that provides class instances and refreshes instance data. This name must be registered with WMI by creating an instance of the __Win32Provider class with the Name property containing this name. When this qualifier is specified on a class whose instances are provided dynamically, the Dynamic qualifier must also be specified.

Applies to: namespace instances

If set to TRUE, RequiresEncryption marks a namespace so that client applications and scripts must connect with encrypted authentication. The authentication level must be set to RPC_C_AUTHN_LEVEL_PKT_PRIVACY in C++. In scripting or Visual Basic, authentication level must be set to WbemAuthenticationLevelPktPrivacy. For more information, see Setting Namepace Security Descriptors. The qualifier is used in MOF with the pragma namespace preprocessor command.

For more information, see Setting the Default Process Security Level Using C++ or Setting the Default Process Security Level Using VBScript. Scripting authentication levels are defined in WbemAuthenticationLevelEnum.

Windows Server 2003, Windows 2000, Windows NT 4.0, Windows XP, and Windows Me/98/95:  Before Windows Server 2003 with SP1, providers could not set namespace security to require encryption before returning data.

Applies to: classes

Designates a class that can only have one instance and that does not contain key properties.

Only the value TRUE (default) is allowed.

Applies to: methods

Indicates whether a method can called by using the class definition or its instances.

The method cannot be invoked from an instance.

Applies to: properties

Indicates that a property of type CIM_DATETIME represents a time interval rather than a specific time.

To identify the property as an interval, the value of this qualifier must be "interval". All other values for this qualifier are reserved for future use.

Applies to: classes

Universally unique identifier applied to the class.

Applies to: properties

Set of values indicating which system privileges must be available and enabled for a successful write operation.
