  • Method Details

    • getProperties

      public Properties getProperties()
      Description copied from interface: ImageThread
      Get the OS-specific properties for this thread.
      Specified by:
      getProperties in interface ImageThread
      Returns:
      a table of OS-specific properties for this thread. Values which are commonly available include
      • "priority" -- the priority of the thread
      • "policy" -- the scheduling policy of the thread

    • getRegisters

      public Iterator<?> getRegisters()
      Description copied from interface: ImageThread
      Get the register contents.
      Specified by:
      getRegisters in interface ImageThread
      Returns:
      an iterator to iterate over the state of the CPU registers when the image was created. The collection may be empty if the register state is not available for this thread. If the CPU supports partial registers (e.g. AH, AL, AX, EAX, RAX on AMD64), only the largest version of the register will be included

    • getStackFrames

      public Iterator<?> getStackFrames() throws DataUnavailable
      Description copied from interface: ImageThread
      Get the set of stack frames on this thread.
      Specified by:
      getStackFrames in interface ImageThread
      Returns:
      an iterator to walk the native stack frames in order from top-of-stack (that is, the most recent frame) to bottom-of-stack. Throws DataUnavailable if native stack frames are not available on this platform.
      Throws:
      DataUnavailable - If native stack frames are not available on this platform

    • getStackSections

      public Iterator<?> getStackSections()
      Description copied from interface: ImageThread
      Get the set of image sections which make up the stack.
      Specified by:
      getStackSections in interface ImageThread
      Returns:
      a collection of ImageSections which make up the stack. On most platforms this consists of a single entry, but on some platforms the thread's stack may consist of non-contiguous sections
