Interface StringObjectValidator<T>

Type Parameters:

T - The type of the payload. The Fernet token encodes the payload in binary. The type T should be a domain object or data transfer object representation of that data.

All Superinterfaces:

Validator<T>

public interface StringObjectValidator<T>
extends Validator<T>

A Validator for payloads that represent objects as Strings (e.g. JSON or XML). This validator converts the payload to a String then delegates to getStringTransformer() to convert that String to an object. If the deserialisation library you use already provides a way to convert binary into objects, then you can use Validator directly instead.

Method Detail

getCharset

default Charset getCharset()

getStringCreator

default Function<byte[],String> getStringCreator()

Override this to specify an alternative way to convert binary data into a String. The default implementation uses the UTF-8 character set.

Returns:

a method for converting a byte array into a String

getTransformer

default Function<byte[],T> getTransformer()

Description copied from interface: Validator

Implement this to define how decrypted content is deserialised into domain objects.

Specified by:

getTransformer in interface Validator<T>

Returns:

a method for converting the decrypted payload into a domain object

getStringTransformer

Function<String,T> getStringTransformer()

Plug in your String deserialisation method here.

Returns:

a method for converting a String into an Object.
