Class AspicParser<T extends Invertable>

java.lang.Object
org.tweetyproject.commons.Parser<AspicArgumentationTheory<T>,Formula>
org.tweetyproject.arg.aspic.parser.AspicParser<T>
Type Parameters:
T - is the type of the language that the ASPIC theory's rules range over
public class AspicParser<T extends Invertable> extends Parser<AspicArgumentationTheory<T>,Formula>
Parses a Aspic Argumentation System out of an input text. Every line contains one of the following:
<order> ::= <identifier> ( '<' <identifier> )+
<ordinary premise> ::= '=>' '-'? <identifier>
<axiom> ::= '->' '-'? <identifier>
<defeasible rule> ::= ( <identifier> ':' )? <identifier> ( ',' <identifier> )* '=>' (-)? <identifier>
<static rule> ::= <identifier> ( ',' <identifier> )* '->' (-)? <identifier>
