35Provides the implementation classes for the <em>local:</em> protocol for
36the HotSpot PerfData instrumentation buffer monitoring implementation.

38<p>
39The <em>local:</em> protocol is the default protocol for the PerfData
40implementation. It utilizes a name shared memory mechanism, identified
41by a backing store file in the file system name space. The location of
42the backing store file is platform specific and is dictated primarily by
43the JVM implementation. However, the <code>java.io.tmpdir</code> system
44property generally contains the location of the files, with the exception
45of the Solaris implementation, as the SDK and HotSpot JVM use different
46locations for their temporary file storage. The HotSpot JVM uses the
47<em>/tmp</em> directory and the SDK uses <em>/var/tmp</em>. The classes
48in this specifically use <em>/tmp</em> when running on Solaris.
