- objectFieldOffset
  
  public final long objectFieldOffset(Field field)
  
  Returns an unspecified, abstract "offset" of the passed Field to specify a generic access of the field's value for an instance of its declaring class that can be used with object-based methods like set_int(Object, long, int). Whether that offset is an actual low-level memory offset relative to an instance' field offset base or simply an index of the passed field in its declaring class' list of fields, is implementation-specific.
  
  Specified by:
  
  objectFieldOffset in interface MemoryAccessor
  
  Parameters:
  
  field - the Field whose abstract offset shall be determined.
  
  Returns:
  
  the passed Field's abstract offset.

  Parameters:
  
  fields - the fields to retrieve the offsets for
  
  Returns:

- objectFieldOffset
  
  public final long objectFieldOffset(Class<?> objectClass, Field field)
  
  Description copied from interface: MemoryAccessor
  
  Similar to MemoryAccessor.objectFieldOffset(Field), but with the specific object class.
  The difference is that the actual object's class is not the declaring class of its fields if it only extends another class but does not declare an object field itself.
