This instance implementing this interface is * an <a href="ManagementFactory.html#MXBean">MXBean</a> * that can be obtained by calling * the {@link ManagementFactory#getThreadMXBean} method or * from the {@link ManagementFactory#getPlatformMBeanServer * platform <tt>MBeanServer</tt>} method. * * <p>The <tt>ObjectName</tt> for uniquely identifying the MXBean for * the thread system within an MBeanServer is: * <blockquote> * {@link ManagementFactory#THREAD_MXBEAN_NAME * <tt>java.lang:type=Threading</tt>} * </blockquote> * * It can be obtained by calling the * {@link PlatformManagedObject#getObjectName} method. * * <h3>Thread ID</h3> * Thread ID is a positive long value returned by calling the * {@link java.lang.Thread#getId} method for a thread. * The thread ID is unique during its lifetime. When a thread * is terminated, this thread ID may be reused. * * <p> Some methods in this interface take a thread ID or an array * of thread IDs as the input parameter and return per-thread information. * * <h3>Thread CPU time</h3> * A Java virtual machine implementation may support measuring * the CPU time for the current thread, for any thread, or for no threads. * * <p> * The {@link #isThreadCpuTimeSupported} method can be used to determine * if a Java virtual machine supports measuring of the CPU time for any * thread. The {@link #isCurrentThreadCpuTimeSupported} method can * be used to determine if a Java virtual machine supports measuring of * the CPU time for the current thread. * A Java virtual machine implementation that supports CPU time measurement * for any thread will also support that for the current thread. * * <p> The CPU time provided by this interface has nanosecond precision * but not necessarily nanosecond accuracy. * * <p> * A Java virtual machine may disable CPU time measurement * by default. * The {@link #isThreadCpuTimeEnabled} and {@link #setThreadCpuTimeEnabled} * methods can be used to test if CPU time measurement is enabled * and to enable/disable this support respectively. * Enabling thread CPU measurement could be expensive in some * Java virtual machine implementations. * * <h3>Thread Contention Monitoring</h3> * Some Java virtual machines may support thread contention monitoring. * When thread contention monitoring is enabled, the accumulated elapsed * time that the thread has blocked for synchronization or waited for * notification will be collected and returned in the * <a href="ThreadInfo.html#SyncStats"><tt>ThreadInfo</tt></a> object. * <p> * The {@link #isThreadContentionMonitoringSupported} method can be used to * determine if a Java virtual machine supports thread contention monitoring. * The thread contention monitoring is disabled by default.
