This optional 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 could be useful for authors who want to ensure that a minimum amount of disk space will be 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 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.
Namespace value is root/CIMV2.
WMI Provider value is MSIProv.
An identifier used in conjunction with other keys to uniquely identify the check
The CheckMode property is used to indicate whether the condition is expected to exist or not exist in the environment. When the value is True, the condition is expected to exist (e.g., a file is expected to be on a system) so invoke() is expected to return True. When the value is False, the condition is not expect to exist (e.g., a file is not to be on a system) so invoke is expected to return false
A description of the objects.
The name used to identify this software element
The name of the directory (as a path, reference to a directory specification or reference to a property) where the space is reserved.
A unique key identifying this reserve cost item within its product.
The number of bytes of disk space reserved if the associated software element is installed to run locally.
The number of bytes of disk space reserved if the associated software element is installed to run from source.
This is an identifier for this software element.
The software element state of a software element
The target operating system of the this software element.
Version should be in the form .. or .
The invoke method is to evaluate a particular check. The details of how the method evaluates a particular check in a CIM context is described by the non-abstract CIM_Check sub classes. The results of the method are based on the return value. - A 0 (zero) is returned if the condition is satisfied. - A 1 (one) is returned if the method is not supported. - Any other value indicates the condition is not satisfied.
