com.fasterxml.jackson.databind.deser.BeanDeserializerFactory

All Implemented Interfaces:

Serializable

public class BeanDeserializerFactory
extends BasicDeserializerFactory
implements Serializable

Concrete deserializer factory class that adds full Bean deserializer construction logic using class introspection. Note that factories specifically do not implement any form of caching: aside from configuration they are stateless; caching is implemented by other components.

Instances of this class are fully immutable as all configuration is done by using "fluent factories" (methods that construct new factory instances with different configuration, instead of modifying instance).

Method Details

withConfig

public DeserializerFactory withConfig(DeserializerFactoryConfig config)

Method used by module registration functionality, to construct a new bean deserializer factory with different configuration settings.

createBeanDeserializer

public JsonDeserializer<Object> createBeanDeserializer(DeserializationContext ctxt,
 JavaType type,
 BeanDescription beanDesc)
                                                throws JsonMappingException

Method that DeserializerCaches call to create a new deserializer for types other than Collections, Maps, arrays and enums.

Specified by:

createBeanDeserializer in class DeserializerFactory

Parameters:

type - Type to be deserialized

Throws:

JsonMappingException

createBuilderBasedDeserializer

public JsonDeserializer<Object> createBuilderBasedDeserializer(DeserializationContext ctxt,
 JavaType valueType,
 BeanDescription valueBeanDesc,
 Class<?> builderClass)
                                                        throws JsonMappingException

Description copied from class: DeserializerFactory

Method called to create a deserializer that will use specified Builder class for building value instances.

Specified by:

createBuilderBasedDeserializer in class DeserializerFactory

Throws:

JsonMappingException

buildBeanDeserializer

public JsonDeserializer<Object> buildBeanDeserializer(DeserializationContext ctxt,
 JavaType type,
 BeanDescription beanDesc)
                                               throws JsonMappingException

Method that is to actually build a bean deserializer instance. All basic sanity checks have been done to know that what we have may be a valid bean type, and that there are no default simple deserializers.

Throws:

JsonMappingException

buildThrowableDeserializer

public JsonDeserializer<Object> buildThrowableDeserializer(DeserializationContext ctxt,
 JavaType type,
 BeanDescription beanDesc)
                                                    throws JsonMappingException

Throws:

JsonMappingException
