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

 * 
 *   NOTE:  This class, and other classes within the
 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
 *   supported for use against Ping Identity, UnboundID, and
 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
 *   for proprietary functionality or for external specifications that are not
 *   considered stable or mature enough to be guaranteed to work in an
 *   interoperable way with other types of LDAP servers.
 * 
 * 

 * The information available in a thread stack trace includes:
 * 
 *   The name of the thread.  This is generally a user-friendly string that
 *       indicates what that thread does within the server.
 *   The thread ID that is assigned to the thread by the JVM.
 *   The stack trace frames for that thread as a list of
 *       {@link StackTraceElement} objects.
 * 
 * See the documentation in the {@link StackTraceMonitorEntry} class for
 * information about accessing the Directory Server stack trace.
