def get_view_url(self, handler_name, *args, **kwds):
"""Returns a full url for the given view, with given argument
a wrapper around tornado's reverse_url with some bells and whistles.
if the handler included the {{objid}} special marker, 'objid'
must be provide to reverse_url to be inserted into the returned
url, and args[0] will be interpreted as the object to be viewed.
If you pass in an object it will automatically be registered
and the objid substituted into the url, but you can also
provide an objid for an object previously registered.
if you want a weakref to be used (to prevent memory leaks) to store
the object in the object registry ,pass in a kwd argument
`_weakref=True` when first viewing the argument.
Note that not all types are supported by weakref.
:param handler_name: Handler class name, or value of view_name used
in @http_handler.
:param obj_or_objid: objid is the return value of a previous call to
registry.register
:param args: values to use in unnamed capture groups in route regexp,
if any. must match the number and order of groups.
:param kwds: values to use in named capture groups in route regexp,
if any must match the number and and names of groups.
Throws: IOError if the server thread failed to initialize
Examples:
@http_handler("/blah/{{objid}}")
class A():
...
get_view_url('A',my_object)
