- SchemaAware, ContextualSerializer, ResolvableSerializer
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 BeanPropertyWriter
s 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(com.fasterxml.jackson.databind.SerializerProvider)
method, and NOT from constructor;
otherwise we could end up with an infinite loop.
BeanSerializer
public BeanSerializer(JavaType type,
BeanSerializerBuilder builder,
BeanPropertyWriter[] properties,
BeanPropertyWriter[] filteredProperties)
- Parameters:
builder
- Builder object that contains collected information
that may be needed for serializerproperties
- Property writers used for actual serialization
BeanSerializer
protected BeanSerializer(BeanSerializerBase src)
- Alternate copy constructor that can be used to construct
standard
BeanSerializer
passing an instance of
"compatible enough" source serializer.
BeanSerializer
protected BeanSerializer(BeanSerializerBase src,
ObjectIdWriter objectIdWriter)
createDummy
public static BeanSerializer createDummy(JavaType forType)
- Method for constructing dummy bean serializer; one that
never outputs any properties
unwrappingSerializer
public JsonSerializer<Object> unwrappingSerializer(NameTransformer unwrapper)
- Description copied from class:
JsonSerializer
- Method that will return serializer instance that produces
"unwrapped" serialization, if applicable for type being
serialized (which is the case for some serializers
that produce JSON Objects as output).
If no unwrapped serializer can be constructed, will simply
return serializer as-is.
Default implementation just returns serializer as-is,
indicating that no unwrapped variant exists
- Overrides:
unwrappingSerializer
in class JsonSerializer<Object>
- Parameters:
unwrapper
- Name transformation to use to convert between names
of unwrapper properties
withObjectIdWriter
protected BeanSerializer withObjectIdWriter(ObjectIdWriter objectIdWriter)
- Description copied from class:
BeanSerializerBase
- Fluent factory used for creating a new instance with different
ObjectIdWriter
.
- Specified by:
withObjectIdWriter
in class BeanSerializerBase
serialize
public final void serialize(Object bean,
com.fasterxml.jackson.core.JsonGenerator jgen,
SerializerProvider provider)
throws IOException,
com.fasterxml.jackson.core.JsonGenerationException
- Main serialization method that will delegate actual output to
configured
BeanPropertyWriter
instances.
- Specified by:
serialize
in class BeanSerializerBase
- Parameters:
bean
- Value to serialize; can not be null.jgen
- Generator used to output resulting Json contentprovider
- Provider that can be used to get serializers for
serializing Objects value contains, if any.
- Throws:
IOException
com.fasterxml.jackson.core.JsonGenerationException
toString
public String toString()
- Overrides:
toString
in class Object
