Class AriesParser

java.lang.Object

workbench.cfgParser.Parser

workbench.cfgParser.AriesParser

All Implemented Interfaces:

Runnable

public class AriesParser
extends Parser

Parser for Aries AUV mission files (i.e. track.out files). The context free grammar that will produce Aries AUV missions is described by the following set of Chomsky Normal Form (CNF) productions: Composite Productions (form of A -> B + C) Mission -> Double + WaypointList Mission -> Double + WaypointCommand WaypointList -> WaypointCommand + WaypointList WaypointList -> WaypointCommand + WaypointCommand WaypointCommand -> WaypointData + AdminData WaypointData -> PositionData + DepthData PositionData -> Position + Speed Position -> Double + Double Speed -> Double + Double DepthData -> Double + Depth Depth -> Double + Double AdminData -> GPSData + WaypointSettings GPSData -> GPSPopup + GPSPopupDuration WaypointSettings -> Double + Double Terminal Productions (form of A -> "b") Double -> "double value"
