__MethodInvocationEvent class

The __MethodInvocationEvent system class is defined but is not implemented.

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 __MethodInvocationEvent : __InstanceOperationEvent
  string       Method;
  __Parameters Parameters;
  boolean      PreCall;
  uint8        SECURITY_DESCRIPTOR[];
  object       TargetInstance;
  uint64       TIME_CREATED;


The __MethodInvocationEvent class has these types of members:


The __MethodInvocationEvent class has these properties.


Data type: string

Access type: Read-only

Method invoked to trigger the event.


Data type: __Parameters

Access type: Read-only

Reference to an instance that represents the input and output parameters of the method call.


Data type: boolean

Access type: Read-only

If TRUE, the event is raised before the method is called.


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, see Security Descriptors.


Data type: object

Access type: Read-only

Instance the method is invoked on. This property is inherited from __InstanceOperationEvent.


Data type: uint64

Access type: Read-only

Unique value that indicates the time 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.


The __MethodInvocationEvent class is derived from __InstanceOperationEvent.
