This class is used by the main API class and should not be used directly. This class tries to extract properties from the User-Agent string itself. This is a completely separate step to the main JSON tree walk but uses the results of the tree walk to optimise the property extraction.

The property extraction is done in two steps:

   1. Try and identify the type of User-Agent and thus the set of
      property extraction rules to run. This is optimised by the
      properties from the tree walk.

   2. Run the rules found in step 1 to try and extract the properties.

Overrides: object.__init__: (inherited documentation)

put_properties(self, user_agent, props_to_vals, properties)

Merge the tree walk properties with the User-Agent string properties using the User-Agent rules.

Parameters:

user_agent - The User-Agent to find properties for.
props_to_vals - The result of the tree walk, a dictionary of property_id:value_id.
properties - The result of the tree walk, a dictionary of properties (Property objects) wrapped in a Properties object.
