Method Summary

Modifier and Type	Method and Description
boolean	isVirtual() Accessor for checking whether there is an actual physical property behind this property abstraction or not.
void	serializeAsElement(java.lang.Object bean, JsonGenerator gen, SerializerProvider prov) Alternative to BeanPropertyWriter.serializeAsField(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider) that is used when a POJO is serialized as JSON Array; the difference is that no field names are written.
void	serializeAsField(java.lang.Object bean, JsonGenerator gen, SerializerProvider prov) 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.
abstract VirtualBeanPropertyWriter	withConfig(MapperConfig<?> config, AnnotatedClass declaringClass, BeanPropertyDefinition propDef, JavaType type) Contextualization method called on a newly constructed virtual bean property.

Method Detail

isVirtual

public boolean isVirtual()

Description copied from interface: BeanProperty

Accessor for checking whether there is an actual physical property behind this property abstraction or not.

Specified by:

isVirtual in interface BeanProperty

Overrides:

isVirtual in class ConcreteBeanPropertyBase

withConfig

public abstract VirtualBeanPropertyWriter withConfig(MapperConfig<?> config,
                                                     AnnotatedClass declaringClass,
                                                     BeanPropertyDefinition propDef,
                                                     JavaType type)

Contextualization method called on a newly constructed virtual bean property. Usually a new intance needs to be created due to finality of some of configuration members; otherwise while recommended, creating a new instance is not strictly-speaking mandatory because calls are made in thread-safe manner, as part of initialization before use.

Parameters:

config - Currenct configuration; guaranteed to be SerializationConfig (just not typed since caller does not have dependency to serialization-specific types)

declaringClass - Class that contains this property writer

propDef - Nominal property definition to use

type - Declared type for the property

serializeAsField

public void serializeAsField(java.lang.Object bean,
                             JsonGenerator gen,
                             SerializerProvider prov)
                      throws java.lang.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:

java.lang.Exception

serializeAsElement

public void serializeAsElement(java.lang.Object bean,
                               JsonGenerator gen,
                               SerializerProvider prov)
                        throws java.lang.Exception

Description copied from class: BeanPropertyWriter

Alternative to BeanPropertyWriter.serializeAsField(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider) that is used when a POJO is serialized as JSON Array; the difference is that no field names are written.

Overrides:

serializeAsElement in class BeanPropertyWriter

Throws:

java.lang.Exception
