Package com.macasaet.fernet

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 Details

    • getCharset

      default java.nio.charset.Charset getCharset()

    • getStringCreator

      default java.util.function.Function<byte[],​java.lang.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 java.util.function.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

      java.util.function.Function<java.lang.String,​T> getStringTransformer()
      Plug in your String deserialisation method here.
      Returns:
      a method for converting a String into an Object.
