052 * This class defines a data structure that can hold information about a thread
053 * stack trace read from the Directory Server's stack trace monitor.

055 * <BLOCKQUOTE>
056 *   <B>NOTE:</B>  This class, and other classes within the
057 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
058 *   supported for use against Ping Identity, UnboundID, and
059 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
060 *   for proprietary functionality or for external specifications that are not
061 *   considered stable or mature enough to be guaranteed to work in an
062 *   interoperable way with other types of LDAP servers.
063 * </BLOCKQUOTE>
064 * <BR>
065 * The information available in a thread stack trace includes:
066 * <UL>
067 *   <LI>The name of the thread.  This is generally a user-friendly string that
068 *       indicates what that thread does within the server.</LI>
069 *   <LI>The thread ID that is assigned to the thread by the JVM.</LI>
070 *   <LI>The stack trace frames for that thread as a list of
071 *       {@link StackTraceElement} objects.</LI>
072 * </UL>
073 * See the documentation in the {@link StackTraceMonitorEntry} class for
074 * information about accessing the Directory Server stack trace.
