Class BeanSerializerBase

java.lang.Object

org.codehaus.jackson.map.JsonSerializer<Object>

org.codehaus.jackson.map.ser.std.SerializerBase<Object>

org.codehaus.jackson.map.ser.std.BeanSerializerBase

All Implemented Interfaces:

ResolvableSerializer, SchemaAware

Direct Known Subclasses:

BeanSerializer, UnwrappingBeanSerializer

public abstract class BeanSerializerBase
extends SerializerBase<Object>
implements ResolvableSerializer, SchemaAware

Base class both for the standard bean serializer, and couple of variants that only differ in small details. Can be used for custom bean serializers as well, although that is not the primary design goal.

Since:

1.9

Method Summary

Modifier and Type	Method	Description
protected BeanPropertyFilter	findFilter(SerializerProvider provider)	Helper method used to locate filter that is needed, based on filter id this serializer was constructed with.
JsonNode	getSchema(SerializerProvider provider, Type typeHint)	Note: since Jackson 1.9, default implementation claims type is "string"
void	resolve(SerializerProvider provider)	Method called after SerializerProvider has registered the serializer, but before it has returned it to the caller.
abstract void	serialize(Object bean, JsonGenerator jgen, SerializerProvider provider)	Method that can be called to ask implementation to serialize values of type this serializer handles.
protected void	serializeFields(Object bean, JsonGenerator jgen, SerializerProvider provider)
protected void	serializeFieldsFiltered(Object bean, JsonGenerator jgen, SerializerProvider provider)	Alternative serialization method that gets called when there is a BeanPropertyFilter that needs to be called to determine which properties are to be serialized (and possibly how)
void	serializeWithType(Object bean, JsonGenerator jgen, SerializerProvider provider, TypeSerializer typeSer)	Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

BeanSerializerBase

public BeanSerializerBase(Class<?> rawType,
 BeanPropertyWriter[] properties,
 BeanPropertyWriter[] filteredProperties,
 AnyGetterWriter anyGetterWriter,
 Object filterId)

BeanSerializerBase

protected BeanSerializerBase(BeanSerializerBase src)

Copy-constructor that is useful for sub-classes that just want to copy all super-class properties without modifications.

Method Details

serialize

public abstract void serialize(Object bean,
 JsonGenerator jgen,
 SerializerProvider provider)
                        throws IOException,
JsonGenerationException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class SerializerBase<Object>

Parameters:

bean - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

IOException

JsonGenerationException

serializeWithType

public void serializeWithType(Object bean,
 JsonGenerator jgen,
 SerializerProvider provider,
 TypeSerializer typeSer)
                       throws IOException,
JsonGenerationException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will ignore serialization of type information, and just calls JsonSerializer.serialize(T, org.codehaus.jackson.JsonGenerator, org.codehaus.jackson.map.SerializerProvider): serializers that can embed type information should override this to implement actual handling. Most common such handling is done by something like:

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, jgen);
  serialize(value, jgen, provider);
  typeSer.writeTypeSuffixForScalar(value, jgen);

Overrides:

serializeWithType in class JsonSerializer<Object>

Parameters:

bean - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

typeSer - Type serializer to use for including type information

Throws:

IOException

JsonGenerationException

serializeFields

protected void serializeFields(Object bean,
 JsonGenerator jgen,
 SerializerProvider provider)
                        throws IOException,
JsonGenerationException

Throws:

IOException

JsonGenerationException

serializeFieldsFiltered

protected void serializeFieldsFiltered(Object bean,
 JsonGenerator jgen,
 SerializerProvider provider)
                                throws IOException,
JsonGenerationException

Alternative serialization method that gets called when there is a BeanPropertyFilter that needs to be called to determine which properties are to be serialized (and possibly how)

Throws:

IOException

JsonGenerationException

Since:

1.7

findFilter

protected BeanPropertyFilter findFilter(SerializerProvider provider)
                                 throws JsonMappingException

Helper method used to locate filter that is needed, based on filter id this serializer was constructed with.

Throws:

JsonMappingException

Since:

1.7

getSchema

public JsonNode getSchema(SerializerProvider provider,
 Type typeHint)
                   throws JsonMappingException

Description copied from class: SerializerBase

Note: since Jackson 1.9, default implementation claims type is "string"

Specified by:

getSchema in interface SchemaAware

Overrides:

getSchema in class SerializerBase<Object>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

Throws:

JsonMappingException

resolve

public void resolve(SerializerProvider provider)
             throws JsonMappingException

Description copied from interface: ResolvableSerializer

Method called after SerializerProvider has registered the serializer, but before it has returned it to the caller. Called object can then resolve its dependencies to other types, including self-references (direct or indirect).

Specified by:

resolve in interface ResolvableSerializer

Parameters:

provider - Provider that has constructed serializer this method is called on.

Throws:

JsonMappingException
