CallbackCustomizableDeserializationStrategy

open class CallbackCustomizableDeserializationStrategy<T>(val descriptor: SerialDescriptor, defaultDeserializeCallback: (decoder: Decoder, jsonElement: JsonElement?) -> T, fallbackDeserialization: (initialException: Throwable, decoder: Decoder, jsonElement: JsonElement?) -> T = { initialException, _, _ -> throw initialException }) : CustomizableDeserializationStrategy<T>

Constructors

constructor(descriptor: SerialDescriptor, defaultDeserializeCallback: (decoder: Decoder, jsonElement: JsonElement?) -> T, fallbackDeserialization: (initialException: Throwable, decoder: Decoder, jsonElement: JsonElement?) -> T = { initialException, _, _ -> throw initialException })

Properties

customDeserializationStrategies

open override val customDeserializationStrategies: Set<CustomizableDeserializationStrategy.JsonDeserializerStrategy<T>>

Contains JsonDeserializerStrategy which will be used in deserialize method when standard RawUpdate serializer will be unable to create RawUpdate (and Update as well)

descriptor

open override val descriptor: SerialDescriptor

Functions

addUpdateDeserializationStrategy

open override fun addUpdateDeserializationStrategy(deserializationStrategy: CustomizableDeserializationStrategy.JsonDeserializerStrategy<T>): Boolean

Adding deserializationStrategy into customDeserializationStrategies for using in case of unknown update

deserialize

open override fun deserialize(decoder: Decoder): T

Trying to get JsonElement if decoder is JsonDecoder. Then it will use defaultDeserializeCallback to deserialize data. In case if defaultDeserializeCallback will throw exception it will firstly try to deserialize data by strategies from customDeserializationStrategies and, if no one will return presented data in Optional it will use fallbackDeserialization as last option to deserialize data

removeUpdateDeserializationStrategy

open override fun removeUpdateDeserializationStrategy(deserializationStrategy: CustomizableDeserializationStrategy.JsonDeserializerStrategy<T>): Boolean

Removing deserializationStrategy from customDeserializationStrategies
