ConverterBallotToOrder

class whalrus.ConverterBallotToOrder

Default converter to a BallotOrder.

This is a default converter to a BallotOrder. It tries to infer the type of input and converts it to an ordered ballot (possibly a ballot of a subclass, such as BallotLevels).

Examples

>>> converter = ConverterBallotToOrder()
>>> converter('a > b ~ c')
BallotOrder(['a', {'b', 'c'}], candidates={'a', 'b', 'c'})
>>> converter(['a', {'b', 'c'}])
BallotOrder(['a', {'b', 'c'}], candidates={'a', 'b', 'c'})
>>> converter({'a': 10, 'b': 7, 'c': 0})
BallotLevels({'a': 10, 'b': 7, 'c': 0}, candidates={'a', 'b', 'c'}, scale=Scale())
>>> converter(BallotOneName('a', candidates={'a', 'b', 'c'}))
BallotOrder(['a', {'b', 'c'}], candidates={'a', 'b', 'c'})
>>> converter(BallotPlurality('a', candidates={'a', 'b', 'c'}))
BallotOrder(['a', {'b', 'c'}], candidates={'a', 'b', 'c'})
>>> converter(BallotVeto('a', candidates={'a', 'b', 'c'}))
BallotOrder([{'b', 'c'}, 'a'], candidates={'a', 'b', 'c'})
