__ClassModificationEvent class

The __ClassModificationEvent system class represents a class modification event, which is a type of intrinsic event generated when a class is changed in the namespace.

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 __ClassModificationEvent : __ClassOperationEvent
{
  object PreviousClass;
  uint8  SECURITY_DESCRIPTOR[];
  object TargetClass;
  uint64 TIME_CREATED;
};
