CIM_EnabledLogicalElement class (Windows)

Applies to: desktop apps only

Abstracts the concept of an element that is enabled and disabled, such as a logical device or a service access point.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Syntax

class CIM_EnabledLogicalElement : CIM_LogicalElement
{
  uint16   EnabledState = 5;
  string   OtherEnabledState;
  uint16   RequestedState = 12;
  uint16   EnabledDefault = 2;
  datetime TimeOfLastStateChange;
};

Properties

The CIM_EnabledLogicalElement class has these properties.

EnabledDefault

Data type: uint16

Access type: Write-only

An enumerated value indicating an administrator's default or startup configuration for the Enabled State of an element. By default, the element is "Enabled" (value=2).

Enabled (2)

Disabled (3)

Not Applicable (5)

Enabled but Offline (6)

No Default (7)

DMTF Reserved (8–32767)

Vendor Reserved (32768–65535)

EnabledState

Data type: uint16

Access type: Read-only

Indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value=4) and starting (value=10) are transient states between enabled and disabled.

Value	Meaning
Unknown 0
Other 1
Enabled 2	The element is or could be executing commands, will process any queued commands, and queues new requests.
Disabled 3	The element will not execute commands and will drop any new requests.
Shutting Down 4	The element is in the process of going to a Disabled state.
Not Applicable 5	The element does not support being enabled or disabled.
Enabled but Offline 6	The element might be completing commands, and will drop any new requests.
In Test 7	The element is in a test state.
Deferred 8	The element might be completing commands, but will queue any new requests.
Quiesce 9	The element is enabled but in a restricted mode. The behavior of the element is similar to the Enabled state (2), but it processes only a restricted set of commands. All other requests are queued.
Starting 10	The element is in the process of going to an Enabled state (2). New requests are queued.
DMTF Reserved 11–32767	Reserved.
Vendor Reserved 32768–65535	Reserved.

 

OtherEnabledState

Data type: string

Access type: Read-only

A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1.

RequestedState

Data type: uint16

Access type: Read-only

RequestedState is an integer enumeration that indicates the last requested or desired state for the element. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. Note that when EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. By default, the RequestedState of the element is 5 ("No Change"). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the element is first "Disabled" and then "Enabled". The distinction between requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as StartService or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. A particular instance of CIM_EnabledLogicalElement might not support RequestStateChange. If this occurs, the value 12 ("Not Applicable") is used.

Enabled (2)

Disabled (3)

Shut Down (4)

No Change (5)

Offline (6)

Test (7)

Deferred (8)

Quiesce (9)

Reboot (10)

Reset (11)

Not Applicable (12)

DMTF Reserved (..)

Vendor Reserved (32768–65535)

TimeOfLastStateChange

Data type: datetime

Access type: Write-only

The date or time when the enabled state of the element last changed. If the state of the element has not changed and this property is populated, then it must be set to a 0 interval value. If a state change was requested, but rejected or not yet processed, the property must not be updated.
