    • getThreadId

      public int getThreadId()
      Description copied from interface: OSThread
      The thread id. The meaning of this value is OS-dependent.

      Description copied from interface: OSThread
      The start time of the thread.
      Returns:
      Returns the start time of the task/thread in number of milliseconds since January 1, 1970.

    • getStartMemoryAddress

      public long getStartMemoryAddress()
      Description copied from interface: OSThread
      The memory address above which this thread can run.
      Specified by:
      getStartMemoryAddress in interface OSThread

    • getContextSwitches

      public long getContextSwitches()
      Description copied from interface: OSThread
      A snapshot of the context switches the thread has done. Since the context switches could be voluntary and non-voluntary, this gives the sum of both.

      Description copied from interface: OSThread
      The number of minor (soft) faults the thread has made which have not required loading a memory page from disk. Sometimes called reclaims. Linux only.
      Specified by:
      getMinorFaults in interface OSThread
      Overrides:
      getMinorFaults in class AbstractOSThread
      Returns:
      minor faults.

    • getMajorFaults

      public long getMajorFaults()
      Description copied from interface: OSThread
      The number of major (hard) faults the thread has made which have required loading a memory page from disk. Linux only.

    • getKernelTime

      public long getKernelTime()
      Description copied from interface: OSThread
      Kernel (privileged) time used by the thread.
      Returns:
      Returns the number of milliseconds the task/thread has executed in kernel/system mode.

      public long getUserTime()
      Description copied from interface: OSThread
      User time used by the thread.
      Returns:
      Returns the number of milliseconds the task/thread has executed in user mode.

    • getUpTime

      public long getUpTime()

    • updateAttributes

      public boolean updateAttributes()
      Description copied from interface: OSThread
      Attempts to updates process attributes. Returns false if the update fails, which will occur if the process no longer exists. Not implemented for macOS, as thread ID is simply an index and not unique.
      Specified by:
      updateAttributes in interface OSThread
      Overrides:
      updateAttributes in class AbstractOSThread
      Returns:
      true if the update was successful, false if the update failed. In addition, on a failed update the thread state will be changed to OSProcess.State.INVALID.
