__ExtrinsicEvent class

The __ExtrinsicEvent system class is an abstract base class that serves as a parent class for all user-defined event types, also known as extrinsic events.

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 __ExtrinsicEvent : __Event
{
  uint8  SECURITY_DESCRIPTOR[];
  uint64 TIME_CREATED;
};

Members

Properties

The __ExtrinsicEvent 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. For more information about constants used to set this security descriptor, see WMI Security Constants.

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.
