Enum ASPOperator.AggregateFunction

java.lang.Object

java.lang.Enum<ASPOperator.AggregateFunction>

net.sf.tweety.lp.asp.syntax.ASPOperator.AggregateFunction

All Implemented Interfaces:

Serializable, Comparable<ASPOperator.AggregateFunction>

Enclosing class:

ASPOperator

public static enum ASPOperator.AggregateFunction
extends Enum<ASPOperator.AggregateFunction>

The following aggregate functions are supported by the ASP-Core-2 standard and by Tweety. 'weight' in this context is the first element of an aggregate element (term tuple).
- #count: Number of elements
- #sum: Sum of weights, used to represent weight constraints.
- #max: Maximum weight
- #min: Minimum weight Clingo additionally includes the #sum+ aggregate function, which represents the sum of positive weights.

Method Detail

values

public static ASPOperator.AggregateFunction[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ASPOperator.AggregateFunction c : ASPOperator.AggregateFunction.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ASPOperator.AggregateFunction valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
