The __ClassOperationEvent system class is a base class for all intrinsic events that relate to a class.

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.

class __ClassOperationEvent : __Event
{
  uint8  SECURITY_DESCRIPTOR[];
  object TargetClass;
  uint64 TIME_CREATED;
};

Properties

The __ClassOperationEvent class has these properties.

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.

TargetClass

Data type: object
Access type: Read-only

Class affected by the event. For creation events, this is the newly created class. For modification events, this is the new version of the changed class. For deletion events, this is the deleted class.

TIME_CREATED

Data type: uint64
Access type: Read-only

Unique value that indicates the time at which the event was 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 Times (UTC) format. This property is inherited from __Event.

For more information about using uint64 values in scripts, see Scripting in WMI.
