isUnwrapping

public boolean isUnwrapping()

Description copied from class: BeanPropertyWriter

Accessor that will return true if this bean property has to support "unwrapping"; ability to replace POJO structural wrapping with optional name prefix and/or suffix (or in some cases, just removal of wrapper name).

Default implementation simply returns false.

Overrides:

 JsonGenerator gen,
 SerializerProvider prov)
                      throws Exception

Overrides:

serializeAsField in class BeanPropertyWriter

Throws:

Exception

assignSerializer

public void assignSerializer(JsonSerializer<Object> ser)

Description copied from class: BeanPropertyWriter

Method called to assign value serializer for property

Overrides:

Traversal method used for things like JSON Schema generation, or POJO introspection.

Specified by:

depositSchemaProperty in interface BeanProperty

Overrides:
