  fr.umlv.tatoo.runtime.lexer.rules.RuleData

public class RuleData
extends Object

This class defined the a regular expression associated with a rule of the lexer. The regular expression is composed by one main automaton, one optional follow automaton and a property beginningOfLineRequired() used to know if the regular expression is restricted to match beginning of line.
