Class ASTNAFLiteral

java.lang.Object

org.tweetyproject.lp.asp.parser.SimpleNode

org.tweetyproject.lp.asp.parser.ASTNAFLiteral

All Implemented Interfaces:

Node

public class ASTNAFLiteral
extends SimpleNode

The ASTNAFLiteral class represents a node in the abstract syntax tree (AST) for literals with negation as failure (NAF) within the context of Answer Set Programming (ASP). This class extends SimpleNode and is used by the ASP parser to handle literals that can be prefixed with NAF.

Constructor Summary

Constructor	Description
ASTNAFLiteral(int id)	Constructs a new ASTNAFLiteral node with the specified identifier.
ASTNAFLiteral(ASPParser p, int id)	Constructs a new ASTNAFLiteral node with the specified parser and identifier.

Method Summary

Modifier and Type	Method	Description
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.

Constructor Details

ASTNAFLiteral

public ASTNAFLiteral(int id)

Constructs a new ASTNAFLiteral node with the specified identifier.

Parameters:

id - The node identifier.

ASTNAFLiteral

public ASTNAFLiteral(ASPParser p,
 int id)

Constructs a new ASTNAFLiteral node with the specified parser and identifier.

Parameters:

p - The ASPParser that is constructing this node.

id - The node identifier.

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.

nafneg

public void nafneg(boolean b)

Sets whether this literal is negated using negation as failure (NAF).

Parameters:

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