NonLatticeCounterExample

public static enum NonLatticeCounterExample.GraphExampleType
extends java.lang.Enum<NonLatticeCounterExample.GraphExampleType>
implements NonLatticeCounterExample.ExampleType

An enumeration type to represent the types of counterexamples that can be found when checking to see if a graph is a lattice.

Enum Constant Summary

Enum Constants

Enum Constant	Description
GRAPHCYCLE	Represents a counterexample where the graph has a cycle.
GREATESTLOWER	Represents a counterexample where some nodes have no greatest lower bound.
LEASTUPPER	Represents a counterexample where some nodes have no least upper bound.

Method Summary

Modifier and Type	Method	Description

Enum Constant Detail

GREATESTLOWER

public static final NonLatticeCounterExample.GraphExampleType GREATESTLOWER

Represents a counterexample where some nodes have no greatest lower bound.

LEASTUPPER

public static final NonLatticeCounterExample.GraphExampleType LEASTUPPER

Represents a counterexample where some nodes have no least upper bound.

GRAPHCYCLE

public static final NonLatticeCounterExample.GraphExampleType GRAPHCYCLE

Represents a counterexample where the graph has a cycle.

Method Detail

values

public static NonLatticeCounterExample.GraphExampleType[] 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 (NonLatticeCounterExample.GraphExampleType c : NonLatticeCounterExample.GraphExampleType.values())
    System.out.println(c);

Returns:

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

valueOf

public static NonLatticeCounterExample.GraphExampleType valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
