| Provides the implementation classes for the <em>local:</em> protocol for |
| the HotSpot PerfData instrumentation buffer monitoring implementation. |
| </p> |
| <p> |
| The <em>local:</em> protocol is the default protocol for the PerfData |
| implementation. It utilizes a name shared memory mechanism, identified |
| by a backing store file in the file system name space. The location of |
| the backing store file is platform specific and is dictated primarily by |
| the JVM implementation. However, the <tt>java.io.tmpdir</em> system |
| property generally contains the location of the files, with the exception |
| of the Solaris implementation, as the SDK and HotSpot JVM use different |
| locations for their temporary file storage. The HotSpot JVM uses the |
| <em>/tmp</em> directory and the SDK uses <em>/var/tmp</em>. The classes |
| in this specifically use <em>/tmp</em> when running on Solaris. |
