ApolloOptionalAdapter

class ApolloOptionalAdapter<T>(wrappedAdapter: Adapter<T>) : Adapter<Optional<@JvmSuppressWildcards T>>

This adapter is used to handle nullable fields when they are represented as Optional. null is deserialized as Optional.Absent.

Constructors

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<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<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
