__NamespaceModificationEvent class
The __NamespaceModificationEvent system class reports a namespace modification event, which is a type of intrinsic event that is generated when a namespace is modified.
The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.
Syntax
class __NamespaceModificationEvent : __NamespaceOperationEvent
{
uint8 SECURITY_DESCRIPTOR[];
__Namespace PreviousNamespace;
uint8 SECURITY_DESCRIPTOR [];
__Namespace TargetNamespace;
uint64 TIME_CREATED;
};
Members
The __NamespaceModificationEvent class has these types of members:
Properties
The __NamespaceModificationEvent class has these properties.
-
PreviousNamespace
-
-
Data type: __Namespace
-
Access type: Read-only
Copy of the original version of a __Namespace instance. The Name property of this instance identifies the namespace that is modified.
-
-
SECURITY_DESCRIPTOR
-
-
Data type: uint8 array
-
Access type: Read-only
Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event.
-
-
SECURITY_DESCRIPTOR
-
-
Data type: uint8 array
-
Access type: Read-only
Descriptor that the event provider uses to determine the users that can receive an event. This property is inherited from __Event.
Note
A NULL access control list (ACL) in the SECURITY_DESCRIPTOR grants unlimited access to everyone all the time. For more information, see Creating a Security Descriptor for a New Object.
-
-
TargetNamespace
-
-
Data type: __Namespace
-
Access type: Read-only
Copy of the __Namespace instance that is modified. The Name property of the __Namespace instance indicates the namespace that is modified. This property is inherited from class __NamespaceOperationEvent.
-
-
TIME_CREATED
-
-
Data type: uint64
-
Access type: Read-only
Unique value that indicates the time that an event is generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Time (UTC) format. This property is inherited from __Event.
For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks
The __NamespaceModificationEvent class is derived from __NamespaceOperationEvent.
The only differences between the target namespace and the previous namespace is the qualifiers and properties except Name.
Note that the Name property of a __Namespace instance cannot change because namespaces cannot be renamed. To modify the name of a namespace, the __Namespace instance must be deleted and re-created with a new name. Therefore, namespace modification events are generated when a change occurs to qualifiers and properties other than Name. A namespace modification event is not generated when any kind of change occurs within the namespace. A namespace modification event is generated only when a namespace instance is modified.
