00010  * An instance of this interface is an abstract representation of a physical
00011  * hardware resource which is monitorable.
00012  * <p>
00013  * An instance of this interface presents an abstract, system-independent
00014  * view of a physical hardware resource which is monitorable. Various
00015  * systems use system-dependent means of representing a physical hardware
00016  * resource. GAT, however, uses an instance of this interface as an operating
00017  * system independent description of a physical hardware resource which
00018  * is monitorable.
00019  * <p>
00020  * An instance of this interface allows on to examine the various properties
00021  * of the physical hardware resource to which this instance
00022  * corresponds. In addition is allows one to monitor the physical
00023  * hardware resource to which this instance corresponds.
