Enum Constant Summary

Enum Constants

Enum Constant	Description
BETWEEN	x ≤ α ≤ y
BETWEEN_EXCLUSIVE	x < α < y
EQUAL	α = x
GREATER_THAN	α > x
GREATER_THAN_OR_EQUAL	α ≥ x
IN	α ∈ {x,y,z...}
LESS_THAN	α < x
LESS_THAN_OR_EQUAL	α ≤ x
NOT_BETWEEN	α < x ∨ α > y
NOT_BETWEEN_EXCLUSIVE	α ≤ x ∨ α ≥ y
NOT_EQUAL	α ≠ x
NOT_IN	α ∉ {x,y,z...}

Method Summary

Modifier and Type	Method	Description
String	description()	Note that the description is resolved from a resource bundle when this enum is loaded, so a Locale change afterwards has no effect.
static Operator	valueOf(String name)	Returns the enum constant of this class with the specified name.
static Operator[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Method Details

values

public static Operator[] 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 Operator 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

description

public String description()

Note that the description is resolved from a resource bundle when this enum is loaded, so a Locale change afterwards has no effect.

Returns:

the operator description
