CIM_BasedOn class

The CIM_BasedOn class represents an association that describes how storage extents can be assembled from lower-level extents. For example, physical extents include protected space extents. Thus, volume sets are assembled from one or more physical or protected space extents. Cache memory can be defined independently and realized in a physical element, or it can be based on volatile or non-volatile storage extents.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from MOF code and includes all inherited properties.

Syntax

class CIM_BasedOn : CIM_Dependency
{
  CIM_StorageExtent REF Antecedent;
  CIM_StorageExtent REF Dependent;
  uint64            EndingAddress;
  uint64            StartingAddress;
};

Members

The CIM_BasedOn class has these types of members:

Properties

The CIM_BasedOn class has these properties.

Antecedent
Data type: CIM_StorageExtent
Access type: Read-only

Reference to the lower-level storage extent. This property is inherited from CIM_Dependency.

Dependent
Data type: CIM_StorageExtent
Access type: Read-only

Reference to the higher-level storage extent. This property is inherited from CIM_Dependency.

EndingAddress
Data type: uint64
Access type: Read-only

Indicates the end of the high-level extent in lower-level storage. This property is useful when mapping non-contiguous extents into a higher-level grouping.

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

StartingAddress
Data type: uint64
Access type: Read-only

Indicates the beginning of the high-level extent in lower-level storage.

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

Remarks

The CIM_BasedOn class is derived from CIM_Dependency.

WMI does not implement this class.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
