Win32_DeviceMemoryAddress Class (Windows)

Win32_DeviceMemoryAddress Class

The Win32_DeviceMemoryAddress WMI class represents a device memory address on a computer system running Windows.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Syntax

class Win32_DeviceMemoryAddress : Win32_SystemMemoryResource
{
  string   Caption;
  string   CreationClassName;
  string   CSCreationClassName;
  string   CSName;
  string   Description;
  uint64   EndingAddress;
  datetime InstallDate;
  string   MemoryType;
  string   Name;
  uint64   StartingAddress;
  string   Status;
};

Methods

The Win32_DeviceMemoryAddress class does not define any methods.

Properties

The Win32_DeviceMemoryAddress class defines the following properties.

Caption

Data type: string
Access type: Read-only

Short description of the object—a one-line string. This property is inherited from CIM_ManagedSystemElement.

CreationClassName

Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen(256)

Name of the first concrete class that appears in the inheritance chain used in the creation of an instance. When used with the other key properties of the class, the property allows all instances of this class and its subclasses to be identified uniquely. This property is inherited from CIM_MemoryMappedIO.

CSCreationClassName

Data type: string
Access type: Read-only

Name of the scoping computer system creation class. This property is inherited from CIM_MemoryMappedIO.

CSName

Data type: string
Access type: Read-only

Name of the scoping computer system. This property is inherited from CIM_MemoryMappedIO.

Description

Data type: string
Access type: Read-only

Description of the object. This property is inherited from CIM_ManagedSystemElement.

EndingAddress

Data type: uint64
Access type: Read-only

Ending address of memory-mapped I/O. This property is inherited from CIM_MemoryMappedIO.

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

InstallDate

Data type: datetime
Access type: Read-only

Date and time the object was installed. This property does not require a value to indicate that the object is installed. This property is inherited from CIM_ManagedSystemElement.

MemoryType

Data type: string
Access type: Read-only

Characteristics of the memory resource on the computer system running Windows. Values are the following.

Value	Meaning
ReadWrite	The memory can be both read and written.
ReadOnly	The memory is read-only.
WriteOnly	The memory can only be written.
Prefetchable	A block of memory is copied from main memory into a small buffer managed by the memory chipset. Repeated read operations from the same part of memory are faster with prefetchable memory.

Name

Data type: string
Access type: Read-only

Label by which the object is known. When subclassed, the property can be overridden to be a key property. This property is inherited from CIM_ManagedSystemElement.

StartingAddress

Data type: uint64
Access type: Read-only
Qualifiers: Key

Starting address of memory-mapped I/O. The hardware resource identifier property should be set to this value to construct the mapped I/O resource key. This property is inherited from CIM_MemoryMappedIO.

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

Status

Data type: string
Access type: Read-only

Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states. This property is inherited from CIM_ManagedSystemElement.

The values are:

"OK"
"Error"
"Degraded"
"Unknown"
"Pred Fail"
"Starting"
"Stopping"
"Service"
"Stressed"
"NonRecover"
"No Contact"
"Lost Comm"

Remarks

The Win32_DeviceMemoryAddress class is derived from Win32_SystemMemoryResource.
