A base sentence class for a particular protocol.
Using this base class, specific sentence classes can almost
automatically be created for a particular protocol (except for the
documentation of course) if that protocol implements the
IPositioningSentenceProducer
interface. To do this, fill the
ALLOWED_ATTRIBUTES class attribute using the
getSentenceAttributes
class method of the producer:
class FooSentence(BaseSentence): """ A sentence for integalactic transmodulator sentences. @ivar transmogrificationConstant: The value used in the transmogrifier while producing this sentence, corrected for gravitational fields. @type transmogrificationConstant: C{Tummy} """ ALLOWED_ATTRIBUTES = FooProtocol.getSentenceAttributes()
