Imports

Abstract class that defines API for objects that can be registered (for BeanSerializerFactory to participate in constructing BeanSerializer instances. This is typically done by modules that want alter some aspects of serialization process; and is preferable to sub-classing of BeanSerializerFactory.

Sequence in which callback methods are called is as follows:

  1. After factory has collected tentative set of properties (instances of BeanPropertyWriter) is sent for modification via changeProperties. Changes can include removal, addition and replacement of suggested properties.
  2. Resulting set of properties are ordered (sorted) by factory, as per configuration, and then orderProperties is called to allow modifiers to alter ordering.
  3. After all bean properties and related information is accumulated, updateBuilder is called with builder, to allow builder state to be modified (including possibly replacing builder itself if necessary)
  4. Once all bean information has been determined, factory creates default BeanSerializer instance and passes it to modifiers using modifySerializer, for possible modification or replacement (by any com.fasterxml.jackson.databind.JsonSerializer instance)

Default method implementations are "no-op"s, meaning that methods are implemented but have no effect.

Method Detail

changePropertiesback to summary
public List<BeanPropertyWriter> changeProperties(SerializationConfig config, BeanDescription beanDesc, List<BeanPropertyWriter> beanProperties)

Method called by BeanSerializerFactory with tentative set of discovered properties. Implementations can add, remove or replace any of passed properties. Properties List passed as argument is modifiable, and returned List must likewise be modifiable as it may be passed to multiple registered modifiers.

modifyArraySerializerback to summary
public JsonSerializer<?> modifyArraySerializer(SerializationConfig config, ArrayType valueType, BeanDescription beanDesc, JsonSerializer<?> serializer)

Method called by DeserializerFactory after it has constructed the standard serializer for given ArrayType to make it possible to either replace or augment this serializer with additional functionality.

Parameters
config:SerializationConfig

Configuration in use

valueType:ArrayType

Type of the value serializer is used for.

beanDesc:BeanDescription

Details of the type in question, to allow checking class annotations

serializer:JsonSerializer<?>

Default serializer that would be used.

Returns:JsonSerializer<?>

Serializer to use; either serializer that was passed in, or an instance method constructed.

public JsonSerializer<?> modifyKeySerializer(SerializationConfig config, JavaType valueType, BeanDescription beanDesc, JsonSerializer<?> serializer)

Method called by DeserializerFactory after it has constructed the default key serializer to use for serializing java.util.Map keys of given type. This makes it possible to either replace or augment default serializer with additional functionality.

Parameters
config:SerializationConfig

Configuration in use

valueType:JavaType

Type of keys the serializer is used for.

beanDesc:BeanDescription

Details of the type in question, to allow checking class annotations

serializer:JsonSerializer<?>

Default serializer that would be used.

Returns:JsonSerializer<?>

Serializer to use; either serializer that was passed in, or an instance method constructed.

modifySerializerback to summary
public JsonSerializer<?> modifySerializer(SerializationConfig config, BeanDescription beanDesc, JsonSerializer<?> serializer)

Method called by BeanSerializerFactory after constructing default bean serializer instance with properties collected and ordered earlier. Implementations can modify or replace given serializer and return serializer to use. Note that although initial serializer being passed is of type BeanSerializer, modifiers may return serializers of other types; and this is why implementations must check for type before casting.

Note

since 2.2, gets called for serializer of those non-POJO types that do not go through any of more specific modifyXxxSerializer methods; mostly for JDK types like java.util.Iterator and such.

orderPropertiesback to summary
public List<BeanPropertyWriter> orderProperties(SerializationConfig config, BeanDescription beanDesc, List<BeanPropertyWriter> beanProperties)

Method called by BeanSerializerFactory with set of properties to serialize, in default ordering (based on defaults as well as possible type annotations). Implementations can change ordering any way they like. Properties List passed as argument is modifiable, and returned List must likewise be modifiable as it may be passed to multiple registered modifiers.

updateBuilderback to summary
public BeanSerializerBuilder updateBuilder(SerializationConfig config, BeanDescription beanDesc, BeanSerializerBuilder builder)

Method called by BeanSerializerFactory after collecting all information regarding POJO to serialize and updating builder with it, but before constructing serializer. Implementations may choose to modify state of builder (to affect serializer being built), or even completely replace it (if they want to build different kind of serializer). Typically, however, passed-in builder is returned, possibly with some modifications.
