PairValue

data class PairValue<F : OutputValue<*>, S : OutputValue<*>>(pairUnwrappedValue: Pair<F, S>) : IterableValue<OutputValue<*>>

An immutable Value that contains two elements, which can be iterated. When a DictionaryValue is iterated, it's equivalent to a list of key-value pairs.

Parameters

type of the first element

type of the second element

Constructors

PairValue

constructor(pairUnwrappedValue: Pair<F, S>)

Properties

destructurableComponents

open override val destructurableComponents: List<OutputValue<*>>

Components that can be the result of a destructuring operation.

unwrappedValue

open override val unwrappedValue: Iterable<OutputValue<*>>

A list of the two elements.

Functions

open override fun <T> accept(visitor: ExpressionVisitor<T>): T

Accepts a visitor.

open override fun <O> accept(visitor: OutputValueVisitor<O>): O

append

fun Expression.append(other: Expression): Expression

Chains two expressions together, which is used in ComposedExpressions.

destructured

open fun destructured(componentCount: Int): List<OutputValue<*>>

Destructures this object into a list of components.

eval

fun Expression.eval(): Value<*>

groupify

fun Iterable<NamedRegexPattern>.groupify(): Regex

Groups a sequence of patterns into a single Regex where every capture group is identified by its token type (name). The result is cached so that repeated calls with the same patterns reuse the compiled Regex.

isNone

fun Value<*>.isNone(): Boolean

Whether this value represents a missing/null value, either as a direct NoneValue or as a value wrapping None, NoneValue, or null.

iterator

open operator override fun iterator(): Iterator<OutputValue<*>>
