ArbitraryVariable

data class ArbitraryVariable(val default: Any, values: List<Any?>) : AbstractPrintableVariable<Any?>

A variable that can take any value from an arbitrary, finite set.

This implementation stores values in an immutable ordered set. Values and the default are non-nullable: an ArbitraryVariable always contains at least a default value and a (possibly empty) set of candidate values.

Constructors

ArbitraryVariable

constructor(default: Any, values: List<Any?>)

constructor(default: Any, vararg values: Double)

Convenience constructor: build from a default value and a vararg of doubles.

constructor(default: Any, values: Iterable<Any?>)

Construct from a default value and any iterable collection of values.

Properties

default

open override val default: Any

the default value (non-nullable)
