java.lang.management.ThreadInfo
Thread information. ThreadInfo contains the information about a thread including:
General thread information
- Thread ID.
- Name of the thread.
Execution information
- Thread state.
- The object upon which the thread is blocked due to:
  - waiting to enter a synchronization block/method, or
  - waiting to be notified in a {@link Object#wait Object.wait} method,or
  - parking due to a {@link java.util.concurrent.locks.LockSupport#park LockSupport.park} call.
- The ID of the thread that owns the object that the thread is blocked.
- Stack trace of the thread.
- List of object monitors locked by the thread.
- List of ownable synchronizers locked by the thread.
Synchronization Statistics
- The number of times that the thread has blocked for synchronization or waited for notification.
- The accumulated elapsed time that the thread has blocked for synchronization or waited for notification since {@link ThreadMXBean#setThreadContentionMonitoringEnabled thread contention monitoring}was enabled. Some Java virtual machine implementation may not support this. The {@link ThreadMXBean#isThreadContentionMonitoringSupported()}method can be used to determine if a Java virtual machine supports this.
This thread information class is designed for use in monitoring of the system, not for synchronization control.
MXBean Mapping
ThreadInfo is mapped to a {@link CompositeData CompositeData}with attributes as specified in the {@link #from from} method. @see ThreadMXBean#getThreadInfo @see ThreadMXBean#dumpAllThreads @author Mandy Chung @version 1.25, 05/05/06 @since 1.5
