Method Details

deserialize

default <T> @Nullable T deserialize(byte[] source,
 ParameterizedTypeReference<T> typeRef)
                             throws SerializationException

Deserialize the given source into an instance of the type described by a ParameterizedTypeReference. Use this variant for generic types such as List<Person> that cannot be expressed as a Class.

Type Parameters:

T - the target type.

Parameters:

source - the JSON representation to read.

typeRef - reference describing the target type.

Returns:

the deserialized object, or null if source is empty or represents JSON null.

Throws:

SerializationException - if the JSON cannot be deserialized.

deserialize

@Nullable Object deserialize(byte[] source,
 ResolvableType type)
                      throws SerializationException

Deserialize the given source into an instance of the type described by ResolvableType. Use this variant for generic types such as List<Person> that cannot be expressed as a Class.

Parameters:

source - the JSON representation to read.

type - reference describing the target type.

Returns:

the deserialized object, or null if source is empty or represents JSON null.

Throws:

SerializationException - if the JSON cannot be deserialized.
