Functions

abstract fun <T : Any> asFacet(p0: Class<T>): T

open fun forEach(p0: Consumer<in ExprValue>)

abstract operator override fun iterator(): Iterator<ExprValue>

Iterates over this value's child elements.

open fun spliterator(): Spliterator<ExprValue>

Properties

abstract val bindings: Bindings<ExprValue>

Returns the Bindings over this value.

ordinalBindings

abstract val ordinalBindings: OrdinalBindings

Returns the OrdinalBindings over this value.

abstract val scalar: Scalar

Returns the Scalar view of this value.

abstract val type: ExprValueType

The type of value independent of its implementation.

Inheritors

Extensions

val ExprValue.address: ExprValue?

fun ExprValue.asNamed(): Named

Wraps this ExprValue as a Named instance.

fun ExprValue.booleanValue(): Boolean

fun ExprValue.bytesValue(): ByteArray

fun ExprValue.cast(targetType: SingleType, typedOpBehavior: TypedOpBehavior, locationMeta: SourceLocationMeta?, defaultTimezoneOffset: ZoneOffset): ExprValue

Casts this ExprValue to the target type.

operator fun ExprValue.compareTo(other: ExprValue): Int

Provides the comparison predicate--which is not a total ordering.

fun ExprValue.dateValue(): LocalDate

fun ExprValue.exprEquals(other: ExprValue): Boolean

Provides the default equality function.

val ExprValue.name: ExprValue?

fun ExprValue.namedValue(nameValue: ExprValue): ExprValue

Binds the given name value as a Named facet delegate over this ExprValue.

fun ExprValue.numberValue(): Number

val ExprValue.orderedNames: List<String>?

orderedNamesValue

fun ExprValue.orderedNamesValue(names: List<String>): ExprValue

Wraps the given ExprValue with a delegate that provides the OrderedBindNames facet.

fun ExprValue.rangeOver(): Iterable<ExprValue>

Implements the FROM range operation. Specifically, this is distinct from the normal ExprValue.iterator in that types that are notExprValueType.isRangeFrom get treated as a singleton as per PartiQL specification.

fun ExprValue.stringify(): String

A very simple string representation--to be used for diagnostic purposes only.

fun ExprValue.stringValue(): String

fun ExprValue.timestampValue(): Timestamp

fun ExprValue.timeValue(): Time

fun ExprValue.toIonValue(ion: IonSystem): IonValue

This method should only be used in case we want to get result from querying an Ion file or an IonValue

fun ExprValue.unnamedValue(): ExprValue

Wraps this ExprValue in a delegate that always masks the Named facet.
