### get_url(self, name) | source code
Look for a name and return the matching URL documentation. First look for a fully qualified name. If not found, try with partial name. If no url exists for the given object, return `None`. Parameters: `name` - the name to look for Returns: `str` the URL that can be used to reach the `name` documentation. `None` if no such URL exists. Raises: `IndexError` - no object found with `name` `DocUrlGenerator.IndexAmbiguous` - more than one object found with a non-fully qualified name; notice that this is an `IndexError` subclass Overrides: UrlGenerator.get_url (inherited documentation)

### load_index(self, f) | source code
Read the content of an index file. Populate the internal maps with the file content using load_records(). Parameters: `f` (`str` or file) - a file name or file-like object fron which read the index.

### load_records(self, records) | source code
Read a sequence of pairs name -> url and populate the internal maps. Parameters: `records` (iterable) - the sequence of pairs (name, url) to add to the maps.

### _exact_matches A map from an object fully qualified name to its URL. Values are both the name as tuple of fragments and as read from the records (see load_records()), mostly to help _partial_names to perform lookup for unambiguous names.

### _partial_names A map from partial names to the fully qualified names they may refer. The keys are the possible left sub-tuples of fully qualified names, the values are list of strings as provided by the index. If the list for a given tuple contains a single item, the partial match is not ambuguous. In this case the string can be looked up in _exact_matches. If the name fragment is ambiguous, a warning may be issued to the user. The items can be used to provide an informative message to the user, to help him qualifying the name in a unambiguous manner.
