deserialize

default T deserialize(Decoder decoder,
                      Deserializer.DecoderContext context,

               throws java.io.IOException

Description copied from interface: Deserializer

Deserializes from the current state of the Decoder an object of type T.

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:

java.io.IOException - If an error occurs during deserialization of the object

allowNull

default boolean allowNull()

Specified by:

allowNull in interface Deserializer<T>

Returns:

Whether the deserializer is allowed to emit null

                          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
