All Implemented Interfaces:

JsonFormatVisitable

public class BeanSerializer
extends BeanSerializerBase

Serializer class that can serialize Java objects that map to JSON Object output. Internally handling is mostly dealt with by a sequence of BeanPropertyWriters that will handle access value to serialize and call appropriate serializers to write out JSON.

Implementation note: we will post-process resulting serializer, to figure out actual serializers for final types. This must be done from BeanSerializerBase.resolve(tools.jackson.databind.SerializationContext) method, and NOT from constructor; otherwise we could end up with an infinite loop.

protected	BeanSerializer(BeanSerializerBase src, ObjectIdWriter objectIdWriter, Object filterId)

Method Summary

Modifier and Type	Method	Description
protected BeanSerializerBase	asArraySerializer()	Implementation has to check whether as-array serialization is possible reliably; if (and only if) so, will construct a BeanAsArraySerializer, otherwise will return this serializer as is.
static BeanSerializer	createDummy(JavaType forType, BeanSerializerBuilder builder)	Method for constructing dummy bean serializer; one that never outputs any properties
void	serialize(Object bean, JsonGenerator gen, SerializationContext provider)	Main serialization method that will delegate actual output to configured BeanPropertyWriter instances.
ValueSerializer<Object>	unwrappingSerializer(NameTransformer unwrapper)	Lets force sub-classes to implement this, to avoid accidental missing of handling...
protected BeanSerializerBase	withByNameInclusion(Set<String> toIgnore, Set<String> toInclude)	Mutant factory used for creating a new instance with additional set of properties to ignore or include (from properties this instance otherwise has)
BeanSerializerBase	withFilterId(Object filterId)	Mutant factory used for creating a new instance with different filter id (used with JsonFilter annotation)
ValueSerializer<?>	withIgnoredProperties(Set<String> toIgnore)	Mutant factory method called to create a new instance after excluding specified set of properties by name, if there is any.
BeanSerializerBase	withObjectIdWriter(ObjectIdWriter objectIdWriter)	Mutant factory used for creating a new instance with different ObjectIdWriter.
protected BeanSerializerBase	withProperties(BeanPropertyWriter[] properties, BeanPropertyWriter[] filteredProperties)	Mutant factory used for creating a new instance with modified set of properties
