PresentAdapter

class PresentAdapter<T>(wrappedAdapter: Adapter<T>) : Adapter<Optional.Present<@JvmSuppressWildcards T>>

PresentAdapter can only express something that's present. Absent values are handled outside the adapter.

This adapter is used to handle optional arguments in operations and optional fields in Input objects.

Constructors

PresentAdapter

constructor(wrappedAdapter: Adapter<T>)

Functions

array

@JvmName(name = "-array")

inline fun <T> Adapter<T>.array(): Adapter<Array<T>>

Note that Arrays require their type to be known at compile time, so we construct an anonymous object with reference to function with reified type parameters as a workaround.

catchToNull

@JvmName(name = "-catchToNull")

fun <T> Adapter<T>.catchToNull(): Adapter<T?>

catchToResult

@JvmName(name = "-catchToResult")

fun <T> Adapter<T>.catchToResult(): Adapter<FieldResult<T>>

errorAware

@JvmName(name = "-errorAware")

fun <T> Adapter<T>.errorAware(): Adapter<T>

fromJson

open override fun fromJson(reader: JsonReader, customScalarAdapters: CustomScalarAdapters): Optional.Present<T>

Deserializes the given Json to the expected Kotlin type.

list

@JvmName(name = "-list")

fun <T> Adapter<T>.list(): ListAdapter<T>

nullable

@JvmName(name = "-nullable")

fun <T : Any> Adapter<T>.nullable(): NullableAdapter<T>

obj

@JvmName(name = "-obj")

fun <T> Adapter<T>.obj(buffered: Boolean = false): ObjectAdapter<T>

optional

@JvmName(name = "-optional")

fun <T> Adapter<T>.~~optional~~(): PresentAdapter<T>

present

@JvmName(name = "-present")

fun <T> Adapter<T>.present(): PresentAdapter<T>

toJson

open override fun toJson(writer: JsonWriter, customScalarAdapters: CustomScalarAdapters, value: Optional.Present<T>)

Serializes a Kotlin type into its equivalent Json representation.

toJsonString

@JvmName(name = "-toJson")

@JvmOverloads

fun <T> Adapter<T>.toJsonString(value: T, customScalarAdapters: CustomScalarAdapters = CustomScalarAdapters.Empty, indent: String? = null): String
