- org.codehaus.jackson.map.JsonSerializer<T>
- - org.codehaus.jackson.map.ser.std.SerializerBase<Object>
  - - org.codehaus.jackson.map.ser.std.NullSerializer

All Implemented Interfaces:

SchemaAware
```
public class NullSerializer
extends SerializerBase<Object>
```
This is a simple dummy serializer that will just output literal JSON null value whenever serialization is requested. Used as the default "null serializer" (which is used for serializing null object references unless overridden), as well as for some more exotic types (java.lang.Void).
