Class ASTVar

java.lang.Object

org.tweetyproject.lp.asp.parser.SimpleNode

org.tweetyproject.lp.asp.parser.ASTVar

All Implemented Interfaces:

Node

public class ASTVar
extends SimpleNode

The ASTVar class represents a variable node in the abstract syntax tree (AST) within the context of Answer Set Programming (ASP). This class extends SimpleNode and is used by the ASP parser to handle and represent variables that are used in rules, facts, and queries within an ASP program.
