所有已实现的接口:: Sentence

public abstract class PositionParser extends SentenceParser

Abstract base class for sentence parsers that handle geographic position or waypoint data and parse NMEA 0183 lat/lon values.

Notice that PositionSentence interface is not implemented by this parser because the extending parser may not always provide current location.
