Win32_ReserveCost class

The Win32_ReserveCost optional WMI class allows the author to reserve a specified amount of disk space in any directory, depending on the installation state of a component. Reserving cost in this way is useful for authors who want to ensure that a minimum amount of disk space is available after the installation is completed. For example, this disk space might be reserved for user documents, or for application files (such as index files) that are created only after the application is launched following installation. The Win32_ReserveCost class also allows custom actions to specify an approximate cost for any files, registry entries, or other items, that the custom action might install.

Note  For more information about support or requirements for installation on a specific operating system, see Operating System Availability of WMI Components.

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

Members

The Win32_ReserveCost class has these types of members:

Methods

The Win32_ReserveCost class has these methods.

MethodDescription
Invoke

Evaluates a particular check. The details of how the method evaluates a particular check in a CIM context are described by the non-abstract CIM_Check subclasses.

 

Properties

The Win32_ReserveCost class has these properties.

Caption
Data type: string
Access type: Read-only

Short textual description of the object.

CheckID
Data type: string
Access type: Read-only

Identifier used in conjunction with other keys to uniquely identify the check.

CheckMode
Data type: boolean
Access type: Read-only

Whether the condition is expected to exist in the environment. When TRUE, the condition is expected to exist (for example, a file is expected to be on a system), so the Invoke method is expected to return TRUE.

Description
Data type: string
Access type: Read-only

Description of the object.

Name
Data type: string
Access type: Read-only

Name used to identify the software element.

ReserveFolder
Data type: string
Access type: Read-only

Name of the directory, as a path, reference to a directory specification or reference to a property, where the space is reserved.

ReserveKey
Data type: string
Access type: Read-only

Unique key that identifies this reserve cost item within its product.

ReserveLocal
Data type: uint32
Access type: Read-only

Number of bytes of disk space reserved if the associated software element is installed to run locally.

ReserveSource
Data type: uint32
Access type: Read-only

Number of bytes of disk space reserved if the associated software element is installed to run from source.

SoftwareElementID
Data type: string
Access type: Read-only

Identifier for the software element.

SoftwareElementState
Data type: uint16
Access type: Read-only

State of a software element.
