Class AbstractDeserializer<T>

java.lang.Object

io.jsonwebtoken.io.AbstractDeserializer<T>

Type Parameters:

T - the type of object returned after deserialization

All Implemented Interfaces:

Deserializer<T>

public abstract class AbstractDeserializer<T>
extends Object
implements Deserializer<T>

Convenient base class to use to implement Deserializers, with subclasses only needing to implement doDeserialize(Reader).

Since:

0.12.0
