JsonDeserializer<T> Interface representing a custom deserializer for Json.
JsonSerializationContext Context for serialization that is passed to a custom serializer during invocation of its JsonSerializer.serialize(Object, Type, JsonSerializationContext) method.
JsonSerializer<T> Interface representing a custom serializer for Json.

Class Summary

JsonParser A parser to parse Json into a parse tree of JsonElements
JsonPrimitive A class representing a Json primitive value.
JsonStreamParser A streaming parser that allows reading of multiple JsonElements from the specified reader asynchronously.

Enum Summary

LongSerializationPolicy Defines the expected format for a long or Long type when its serialized.
