Known subclasses: twisted.positioning.nmea.NMEAProtocol
A mixin for certain protocols that produce positioning sentences.
This mixin helps protocols that store the layout of sentences that they
consume in a _SENTENCE_CONTENTS class variable provide all
sentence attributes that can ever occur. It does this by providing a class
method, getSentenceAttributes, which iterates over all
sentence types and collects the possible sentence attributes.
| Class Method | getSentenceAttributes | Returns a set of all attributes that might be found in the sentences produced by this protocol. |
