public static final Bound OPEN

An open bound does not include its end-point.

CLOSED

public static final Bound CLOSED

A closed bound includes its end-point.

ABSENT

public static final Bound ABSENT

An absent bound means that the range extends to infinity.

Method Details

values

public static Bound[] values()

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

Returns:

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

valueOf

public static Bound valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

flip

public Bound flip()

Returns the bound with the reverse sense.

An open bound, "x > 0", becomes a closed bound when negated to "x <= 0", and vice versa.
