Enum Operands.Associativity

java.lang.Object

java.lang.Enum<Operands.Associativity>

org.projog.core.parser.Operands.Associativity

All Implemented Interfaces:

Serializable, Comparable<Operands.Associativity>, java.lang.constant.Constable

Enclosing class:

Operands

private static enum Operands.Associativity
extends Enum<Operands.Associativity>

Associativity is used to specify rules over operators in the same expression that have the same priority.

A "y" means that the argument can contain operators of the same or lower level of priority than the operator represented by "f", while a "x" means that the argument can only contain operators of a lower priority.

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

Returns:

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

valueOf

public static Operands.Associativity valueOf(String name)
