Class RemusParser

java.lang.Object

workbench.cfgParser.Parser

workbench.cfgParser.RemusParser

All Implemented Interfaces:

Runnable

public class RemusParser
extends Parser

Parser for Remus AUV mission files. The context free grammar that will produce Remus AUV missions is described by the following set of Chomsky Normal Form (CNF) productions: Composite Productions (form of A -> B + C) Mission -> NullLocation + Objective Mission -> LocationList + Objective Mission -> NullLocation + ObjectiveList Mission -> LocationList + ObjectiveList NullLocation -> LocationToken + NullLocationParameter NullLocationParameter -> TypeKeyword + NullWaypointKeyword LocationList -> Location + NullLocation LocationList -> Location + LocationList ObjectiveList -> Objective + Objective ObjectiveList -> Objective + ObjectiveList Location -> LocationToken + Attribute Location -> LocationToken + Attributes Objective -> ObjectiveToken + Attribute Objective -> ObjectiveToken + Attributes Attributes -> Attribute + Attribute Attributes -> Attribute + Attributes Attribute -> Keyword + Definition (various) Terminal Productions (form of A -> "b") Double -> "double value" String -> "string value"
