Method Detail

deserializeNonNull

public java.lang.Object deserializeNonNull(Decoder decoder,
                                           Deserializer.DecoderContext decoderContext,

                                    throws java.io.IOException

Description copied from interface: NullableDeserializer

A method that is invoked when the value is known not to be null.

Specified by:

deserializeNonNull in interface NullableDeserializer<java.lang.Object>

Parameters:

decoder - The decoder

decoderContext - The decoder context

type - The type

Returns:

The value

Throws:

java.io.IOException - if something goes wrong during deserialization

allowNull

public boolean allowNull()

Specified by:

allowNull in interface Deserializer<java.lang.Object>

Specified by:

allowNull in interface NullableDeserializer<java.lang.Object>

Returns:

Whether the deserializer is allowed to emit null

getDeserializableBean

public <T> io.micronaut.serde.support.deserializers.DeserBean<T> getDeserializableBean(io.micronaut.core.type.Argument<T> type,
                                                                                       Deserializer.DecoderContext decoderContext)

deserializeInto

public void deserializeInto(Decoder decoder,
                            Deserializer.DecoderContext decoderContext,
                            io.micronaut.core.type.Argument<? super java.lang.Object> type,
                            java.lang.Object value)
                     throws java.io.IOException

Description copied from interface: UpdatingDeserializer

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

Specified by:

deserializeInto in interface UpdatingDeserializer<java.lang.Object>

Parameters:

decoder - The decoder, never null

decoderContext - The decoder context, never null

type - The generic type to be deserialized

value - The value

Throws:

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