Method Detail

rename

public UnwrappingBeanPropertyWriter rename(NameTransformer transformer)

Overrides:

rename in class BeanPropertyWriter

_new

Overridable factory method used by sub-classes

Since:

2.6.0

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:

isUnwrapping in class BeanPropertyWriter

                      throws Exception

Description copied from class: BeanPropertyWriter

Method called to access property that this bean stands for, from within given bean, and to serialize it as a JSON Object field using appropriate serializer.

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:

assignSerializer in class BeanPropertyWriter

depositSchemaProperty

public void depositSchemaProperty(JsonObjectFormatVisitor visitor,
                                  SerializerProvider provider)
                           throws JsonMappingException

Description copied from class: PropertyWriter

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

Specified by:
