StringObjectValidator (Fernet Java 1.4.2 API)

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()
```
