Method Details

createSpecific

default @NonNull Serializer<T> createSpecific(@NonNull Serializer.EncoderContext context,
 @NonNull io.micronaut.core.type.Argument<? extends T> type)
                                       throws SerdeException

Create a more specific serializer for the given definition.

Parameters:

context - The encoder context

type - The type definition including any annotation metadata

Returns:

The more specific serializer

Throws:

SerdeException

serialize

void serialize(@NonNull Encoder encoder,
 @NonNull Serializer.EncoderContext context,
 @NonNull io.micronaut.core.type.Argument<? extends T> type,
 @NonNull T value)
        throws IOException

Serializes the given value using the passed Encoder.

Parameters:

encoder - The encoder to use

context - The encoder context, never null

type - Models the generic type of the value

value - The value, can be null

Throws:

IOException - If an error occurs during serialization

isEmpty

default boolean isEmpty(@NonNull Serializer.EncoderContext context,
 @Nullable T value)

Used for JsonInclude.Include#NON_EMPTY checking.

Parameters:

context - The encoder context

value - The check to check

Returns:

Return true if the value is empty

isAbsent

default boolean isAbsent(@NonNull Serializer.EncoderContext context,
 @Nullable T value)

Used for JsonInclude.Include#NON_ABSENT checking.

Parameters:

context - The encoder context

value - The value to check

Returns:

Return true if the value is absent

isDefault

default boolean isDefault(@NonNull Serializer.EncoderContext context,
 @NonNull T value)

Used for JsonInclude.Include#NON_DEFAULT checking.

Parameters:

context - The encoder context

value - The check to check

Returns:

Return true if the value is the default value
