Class ASTOptFunc

java.lang.Object

org.tweetyproject.lp.asp.parser.SimpleNode

org.tweetyproject.lp.asp.parser.ASTOptFunc

All Implemented Interfaces:

Node

public class ASTOptFunc
extends SimpleNode

The ASTOptFunc class represents a node in the abstract syntax tree (AST) for an optimization function within the context of Answer Set Programming (ASP). This class extends SimpleNode and is used by the ASP parser to handle optimization functions that specify whether to maximize or minimize a particular objective.

Field Summary

Fields

Modifier and Type	Field	Description
String	func	The name or representation of the optimization function.
boolean	maximize	Indicates whether the optimization function is set to maximize.

Constructor Summary

Constructors

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

Method Summary

Modifier and Type	Method	Description
void	func(String f)	Sets the name or representation of the optimization function.
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.
void	maximize(boolean b)	Sets whether the optimization function is to maximize or minimize.

Field Details

func

public String func

The name or representation of the optimization function.

maximize

public boolean maximize

Indicates whether the optimization function is set to maximize. If true, the function is to maximize; if false, to minimize.

Constructor Details

ASTOptFunc

public ASTOptFunc(int id)

Constructs a new ASTOptFunc node with the specified identifier.

Parameters:

id - The node identifier.

ASTOptFunc

public ASTOptFunc(ASPParser p,
 int id)

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

Parameters:

p - The ASPParser that is constructing this node.

id - The node identifier.

Method Details

func

public void func(String f)

Sets the name or representation of the optimization function.

Parameters:

f - The string representing the optimization function.

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.

maximize

public void maximize(boolean b)

Sets whether the optimization function is to maximize or minimize.

Parameters:

b - true to set the function to maximize, false to minimize.
