Class ASTLiteral

java.lang.Object

org.tweetyproject.lp.asp.parser.SimpleNode

org.tweetyproject.lp.asp.parser.ASTLiteral

All Implemented Interfaces:

Node

public class ASTLiteral
extends SimpleNode

The ASTLiteral class represents a node in the abstract syntax tree (AST) for literals within the context of Answer Set Programming (ASP). This class extends SimpleNode and is used by the ASP parser to handle literal expressions, which may include a name and an optional negation.

Method Details

jjtAccept

public Object jjtAccept(ASPParserVisitor visitor,
 Object data)

Accepts a visitor object, which implements the ASPParserVisitor interface, and allows it to process this node in the AST.

Specified by:

jjtAccept in interface Node

Overrides:

jjtAccept in class SimpleNode

Parameters:

visitor - The visitor object that processes this node.

data - Additional data that might be needed for the visitor's processing.

Returns:

The result of the visitor's processing, typically dependent on the visitor's implementation.

neg

public void neg(boolean b)

Sets whether this literal is negated.

Parameters:

b - true if the literal is negated, false otherwise.

name

public void name(String n)

Sets the name of the literal represented by this AST node.

Parameters:

n - The string representing the name of the literal.
