  • Method Details

    • deserialize

      default T deserialize(Decoder decoder, Deserializer.DecoderContext context, io.micronaut.core.type.Argument<? super T> type) throws IOException
      Description copied from interface: Deserializer
      Deserializes from the current state of the Decoder an object of type Deserializer.
      Specified by:
      deserialize in interface Deserializer<T>
      Parameters:
      decoder - The decoder, never null
      context - The decoder context, never null
      type - The generic type to be deserialized
      Returns:
      The deserialized object or null only if Deserializer.allowNull() returns true
      Throws:
      IOException - If an error occurs during deserialization of the object

    • deserializeNullable

      default T deserializeNullable(@NonNull @NonNull Decoder decoder, @NonNull @NonNull Deserializer.DecoderContext context, @NonNull @NonNull io.micronaut.core.type.Argument<? super T> type) throws IOException
      Description copied from interface: Deserializer
      Deserializes from the current state of the Decoder an object of type Deserializer. If the decoder value is null, this must be permitted. By default, in this case, this method will return null.
      Specified by:
      deserializeNullable in interface Deserializer<T>
      Parameters:
      decoder - The decoder, never null
      context - The decoder context, never null
      type - The generic type to be deserialized
      Returns:
      The deserialized object or null
      Throws:
      IOException - If an error occurs during deserialization of the object

    • allowNull

      default boolean allowNull()
      Description copied from interface: Deserializer
      Return true if the decoder can accept the null value by converting it to something else or just returning null.
      Specified by:
      allowNull in interface Deserializer<T>
      Returns:
      Whether the deserializer is allowed to emit null

    • getDefaultValue

      default T getDefaultValue(Deserializer.DecoderContext context, io.micronaut.core.type.Argument<? super T> type)
      Description copied from interface: Deserializer
      Obtains a default value that can be returned from this deserializer in the case where a value is absent.
      Specified by:
      getDefaultValue in interface Deserializer<T>
      Parameters:
      context - The decoder context, never null
      type - The generic type to be deserialized
      Returns:
      The default value
