Detailed Description
An instance of this class is a description of a hardware resource, a physical thing, which a may be required by a hardware or software component.
To clarify the concept of a HardwareResourceDescription, let us give various examples. Memory is described by a HardwareResourceDescription; a network is described by a HardwareResourceDescription; disk space is described by a HardwareResourceDescription; a monitor is described a HardwareResourceDescription\ldots However, an application is not described by a HardwareResourceDescription. In general any resource which corresponds to a physical thing is described by a HardwareResourceDescription.
Hardware is generally useless without software. For example, a disk drive without the appropriate software driver is all but useless. Similarly, hardware often depends upon other hardware. For example, having a disk drive without a computer again is not of much use. Hence, in describing a hardware component one needs to also describe the software and hardware that this hardware component requires. This is reflected in the fact that a HardwareResourceDescription contains in addition to a description of a hardware component a list of HardwareResourceDescriptions, each element of which describes a hardware component upon which the parent hardware component depends, and a list of SoftwareResourceDescriptions, each element of which describes a software component upon which the parent hardware component depends. Hence, the entire structure is recursive.
To construct an instance of a HardwareResourceDescription one requires three quantities:
- A map which contains a set of name/value pairs, detailed later, which describe a hardware resource.
- A list of SoftwareResourceDescription instances each of which describes a software resource upon which the parent hardware resource depends. A list of HardwareResourceDescription instances each of which describes a hardware resource upon which the parent hardware resource depends.
The GAT-API defines a minimum set of supported name/value pairs which can be included in the java.util.Map used to construct a HardwareResourceDescription instance. This minimum set of name/value pairs MUST be supported by any implementation of the GAT-API. This minimum set of supported name/values is given in the table
