The wadllib library helps a web client navigate the resources exposed by a web service. The service defines its resources in a single WADL file. wadllib parses this file and gives access to the resources defined inside. The client code can see the capabilities of a given resource and make the corresponding HTTP requests. If a request returns a representation of the resource, the client can bind the string representation to the wadllib Resource object. ) � Application�Link�Method�NoBoundRepresentationError� Parameter�RepresentationDefinition�ResponseDefinition�Resource� ResourceType� WADLError� N)�quote)� urlencode)�URI�merge)� _make_unicode� _string_types)� iso_strptimez xmlns:mapz http://www.w3.org/2001/XMLSchemac C s d| S )z)Scope a tag name with the WADL namespace.z&{http://research.sun.com/wadl/2006/10}� ��tag_namer r �5/usr/lib/python3/dist-packages/wadllib/application.py�wadl_tagH s r c C s dt | � S )z#Turn a tag name into an XPath path.z./)r r r r r � wadl_xpathM s r c G s$ i }| D ] }|dur|� |� q|S )z<Merge any number of dictionaries, some of which may be None.N)�update)�dicts�final�dictr r r � _merge_dictsR s �r c @ � e Zd ZdZdS )r zAAn exception having to do with the state of the WADL application.N��__name__� __module__� __qualname__�__doc__r r r r r [ s r c @ r )r aA An unbound resource was used where wadllib expected a bound resource.
