Class PhoenixParser

java.lang.Object

workbench.cfgParser.Parser

workbench.cfgParser.PhoenixParser

All Implemented Interfaces:

Runnable

public class PhoenixParser
extends Parser

Parser for Phoenix AUV mission files. The context free grammar that will produce Phoenix AUV missions is described by the following set of Chomsky Normal Form (CNF) productions: Composite Productions (form of A -> B + C) Mission -> Command + Mission Mission -> Command + Command Command -> DepthToken + Number Command -> WaypointToken + Position_2D Command -> WaypointToken + Position_3D Command -> WaypointToken + Position_3D_And_RPM Position_3D_And_RPM -> Position_3D + Number Position_3D -> Position_2D + Number Position_2D -> Number + Number Command -> RudderToken + Number Command -> HeadingToken + Number Command -> PlanesToken + Number Command -> RotateToken + Number Command -> LateralToken + Number Terminal Productions (form of A -> "b") Number -> "double value" DepthToken -> "DEPTH" WaypointToken -> "WAYPOINT" QuitToken -> "QUIT"
