public Class HotSpotThreadImpl

Overrides sun.management.ThreadImpl.getCurrentThreadAllocatedBytes.

Overrides default com.sun.management.ThreadMXBean.getCurrentThreadAllocatedBytes.

Doc from com.sun.management.ThreadMXBean.getCurrentThreadAllocatedBytes.

Returns an approximation of the total amount of memory, in bytes, allocated in heap memory for the current thread. The returned value is an approximation because some Java virtual machine implementations may use object allocation mechanisms that result in a delay between the time an object is allocated and the time its size is recorded.

This is a convenience method for local management use and is equivalent to calling:

  getThreadAllocatedBytes(Thread.currentThread().threadId());

@Override

Overrides sun.management.ThreadImpl.getThreadAllocatedBytes.

Implements com.sun.management.ThreadMXBean.getThreadAllocatedBytes.

Doc from com.sun.management.ThreadMXBean.getThreadAllocatedBytes.

Returns an approximation of the total amount of memory, in bytes, allocated in heap memory for the thread with the specified ID. The returned value is an approximation because some Java virtual machine implementations may use object allocation mechanisms that result in a delay between the time an object is allocated and the time its size is recorded.

If the thread with the specified ID is a virtual thread, is not alive, or does not exist, this method returns -1. If thread memory allocation measurement is disabled, this method returns -1. A thread is alive if it has been started and has not yet terminated.

If thread memory allocation measurement is enabled after the thread has started, the Java virtual machine implementation may choose any time up to and including the time that the capability is enabled as the point where thread memory allocation measurement starts.

@Override

Overrides sun.management.ThreadImpl.getThreadAllocatedBytes.

Implements com.sun.management.ThreadMXBean.getThreadAllocatedBytes.

Doc from com.sun.management.ThreadMXBean.getThreadAllocatedBytes.

Returns an approximation of the total amount of memory, in bytes, allocated in heap memory for each thread whose ID is in the input array ids. The returned values are approximations because some Java virtual machine implementations may use object allocation mechanisms that result in a delay between the time an object is allocated and the time its size is recorded.

This method is equivalent to calling the getThreadAllocatedBytes(long) method for each thread ID in the input array ids and setting the returned value in the corresponding element of the returned array.

Annotations

@Override

Overrides sun.management.ThreadImpl.getThreadCpuTime.

Implements com.sun.management.ThreadMXBean.getThreadCpuTime.

Doc from com.sun.management.ThreadMXBean.getThreadCpuTime.

Returns the total CPU time for each thread whose ID is in the input array ids in nanoseconds. The returned values are of nanoseconds precision but not necessarily nanoseconds accuracy.

This method is equivalent to calling the ThreadMXBean#getThreadCpuTime(long) method for each thread ID in the input array ids and setting the returned value in the corresponding element of the returned array.

Annotations

@Override

Overrides sun.management.ThreadImpl.getThreadUserTime.

Implements com.sun.management.ThreadMXBean.getThreadUserTime.

Doc from com.sun.management.ThreadMXBean.getThreadUserTime.

Returns the CPU time that each thread whose ID is in the input array ids has executed in user mode in nanoseconds. The returned values are of nanoseconds precision but not necessarily nanoseconds accuracy.

This method is equivalent to calling the ThreadMXBean#getThreadUserTime(long) method for each thread ID in the input array ids and setting the returned value in the corresponding element of the returned array.

Annotations

@Override

Overrides sun.management.ThreadImpl.getTotalThreadAllocatedBytes.

Overrides default com.sun.management.ThreadMXBean.getTotalThreadAllocatedBytes.

Doc from com.sun.management.ThreadMXBean.getTotalThreadAllocatedBytes.

Returns an approximation of the total amount of memory, in bytes, allocated in heap memory by all threads since the Java virtual machine started. The returned value is an approximation because some Java virtual machine implementations may use object allocation mechanisms that result in a delay between the time an object is allocated and the time its size is recorded.

Annotations

@Override

Overrides sun.management.ThreadImpl.isThreadAllocatedMemoryEnabled.

Implements com.sun.management.ThreadMXBean.isThreadAllocatedMemoryEnabled.

Doc from com.sun.management.ThreadMXBean.isThreadAllocatedMemoryEnabled.

Tests if thread memory allocation measurement is enabled.

Annotations

@Override

Overrides sun.management.ThreadImpl.isThreadAllocatedMemorySupported.

Implements com.sun.management.ThreadMXBean.isThreadAllocatedMemorySupported.

Doc from com.sun.management.ThreadMXBean.isThreadAllocatedMemorySupported.

Tests if the Java virtual machine implementation supports thread memory allocation measurement.

Annotations

@Override

Overrides sun.management.ThreadImpl.setThreadAllocatedMemoryEnabled.

Implements com.sun.management.ThreadMXBean.setThreadAllocatedMemoryEnabled.

Doc from com.sun.management.ThreadMXBean.setThreadAllocatedMemoryEnabled.

Enables or disables thread memory allocation measurement. The default is platform dependent.
