Returns the ID of the thread associated with this ThreadInfo.

Returns the name of the thread associated with this ThreadInfo.

Returns the state of the thread associated with this ThreadInfo.

Returns the approximate accumulated elapsed time (in milliseconds) that the thread associated with this ThreadInfo has blocked to enter or reenter a monitor since thread contention monitoring is enabled. I.e. the total accumulated time the thread has been in the BLOCKED state since thread contention monitoring was last enabled. This method returns -1 if thread contention monitoring is disabled.

The Java virtual machine may measure the time with a high resolution timer. This statistic is reset when the thread contention monitoring is reenabled.

Returns the total number of times that the thread associated with this ThreadInfo blocked to enter or reenter a monitor. I.e. the number of times a thread has been in the BLOCKED state.

Returns the approximate accumulated elapsed time (in milliseconds) that the thread associated with this ThreadInfo has waited for notification since thread contention monitoring is enabled. I.e. the total accumulated time the thread has been in the WAITING or TIMED_WAITING state since thread contention monitoring is enabled. This method returns -1 if thread contention monitoring is disabled.

The Java virtual machine may measure the time with a high resolution timer. This statistic is reset when the thread contention monitoring is reenabled.

Returns the total number of times that the thread associated with this ThreadInfo waited for notification. I.e. the number of times that a thread has been in the WAITING or TIMED_WAITING state.

Returns the LockInfo of an object for which the thread associated with this ThreadInfo is blocked waiting. A thread can be blocked waiting for one of the following:

• an object monitor to be acquired for entering or reentering a synchronization block/method.
  The thread is in the BLOCKED state waiting to enter the synchronized statement or method.

• an object monitor to be notified by another thread.
  The thread is in the WAITING or TIMED_WAITING state due to a call to the Object.wait method.

• a synchronization object responsible for the thread parking.
  The thread is in the WAITING or TIMED_WAITING state due to a call to the LockSupport.park method. The synchronization object is the object returned from LockSupport.getBlocker method. Typically it is an ownable synchronizer or a Condition.

This method returns null if the thread is not in any of the above conditions.

Returns the string representation of an object for which the thread associated with this ThreadInfo is blocked waiting. This method is equivalent to calling:

 getLockInfo().toString()
 

This method will return null if this thread is not blocked waiting for any object or if the object is not owned by any thread.

Returns the ID of the thread which owns the object for which the thread associated with this ThreadInfo is blocked waiting. This method will return -1 if this thread is not blocked waiting for any object or if the object is not owned by any thread.

Returns the name of the thread which owns the object for which the thread associated with this ThreadInfo is blocked waiting. This method will return null if this thread is not blocked waiting for any object or if the object is not owned by any thread.

Returns the stack trace of the thread associated with this ThreadInfo. If no stack trace was requested for this thread info, this method will return a zero-length array. If the returned array is of non-zero length then the first element of the array represents the top of the stack, which is the most recent method invocation in the sequence. The last element of the array represents the bottom of the stack, which is the least recent method invocation in the sequence.

Some Java virtual machines may, under some circumstances, omit one or more stack frames from the stack trace. In the extreme case, a virtual machine that has no stack trace information concerning the thread associated with this ThreadInfo is permitted to return a zero-length array from this method.

Tests if the thread associated with this ThreadInfo is suspended. This method returns true if Thread.suspend() has been called.

Tests if the thread associated with this ThreadInfo is executing native code via the Java Native Interface (JNI). The JNI native code does not include the virtual machine support code or the compiled native code generated by the virtual machine.

Returns a string representation of this thread info. The format of this string depends on the implementation. The returned string will typically include the thread name, the thread ID, its state, and a stack trace if any.

Returns a ThreadInfo object represented by the given CompositeData. The given CompositeData must contain the following attributes unless otherwise specified below:

Attribute Name	Type
threadId	java.lang.Long
threadName	java.lang.String
threadState	java.lang.String
suspended	java.lang.Boolean
inNative	java.lang.Boolean
blockedCount	java.lang.Long
blockedTime	java.lang.Long
waitedCount	java.lang.Long
waitedTime	java.lang.Long
lockInfo	javax.management.openmbean.CompositeData - the mapped type for LockInfo as specified in the type mapping rules of MXBeans. If cd does not contain this attribute, the LockInfo object will be constructed from the value of the lockName attribute.
lockName	java.lang.String
lockOwnerId	java.lang.Long
lockOwnerName	java.lang.String
stackTrace	javax.management.openmbean.CompositeData[] Each element is a CompositeData representing StackTraceElement containing the following attributes: Attribute Name Type className java.lang.String methodName java.lang.String fileName java.lang.String lineNumber java.lang.Integer nativeMethod java.lang.Boolean
lockedMonitors	javax.management.openmbean.CompositeData[] whose element type is the mapped type for MonitorInfo as specified in the Monitor.from method. If cd does not contain this attribute, this attribute will be set to an empty array.
lockedSynchronizers	javax.management.openmbean.CompositeData[] whose element type is the mapped type for LockInfo as specified in the type mapping rules of MXBeans. If cd does not contain this attribute, this attribute will be set to an empty array.

Returns an array of MonitorInfo objects, each of which represents an object monitor currently locked by the thread associated with this ThreadInfo. If no locked monitor was requested for this thread info or no monitor is locked by the thread, this method will return a zero-length array.

Returns an array of LockInfo objects, each of which represents an ownable synchronizer currently locked by the thread associated with this ThreadInfo. If no locked synchronizer was requested for this thread info or no synchronizer is locked by the thread, this method will return a zero-length array.
