Method Detail

values

public static Algebra.Relation[] 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 (Algebra.Relation c : Algebra.Relation.values())
    System.out.println(c);

Returns:

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

valueOf

public static Algebra.Relation 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

isRelationBetween

public abstract <T extends java.lang.Comparable<T>> boolean isRelationBetween(Interval<T> x,
                                                                              Interval<T> y)

Check if x and y satisfy a certain relation.

Type Parameters:

T - a Comparable type

Parameters:

x - an interval

y - another interval

Returns:

true is iff x and y satisfy the relation
