public class BeanDeserializerBuilder
extends Object

Builder class used for aggregating deserialization information about a POJO, in order to build a JsonDeserializer for deserializing intances.

protected BeanDescription	_beanDesc
protected JsonPOJOBuilder.Value	_builderConfig In addition, Builder may have additional configuration
protected AnnotatedMethod	_buildMethod When creating Builder-based deserializers, this indicates method to call on builder to finalize value.
protected boolean	_defaultViewInclusion
protected HashSet<String>	_ignorableProps Set of names of properties that are recognized but are to be ignored for deserialization purposes (meaning no exception is thrown, value is just skipped).
protected boolean	_ignoreAllUnknown Flag that can be set to ignore and skip unknown properties.

Constructor Summary

protected	BeanDeserializerBuilder(BeanDeserializerBuilder src) Copy constructor for sub-classes to use, when constructing custom builder instances

Method Summary

void	addBackReferenceProperty(String referenceName, SettableBeanProperty prop) Method called to add a property that represents so-called back reference; reference that "points back" to object that has forward reference to currently built bean.
void	addCreatorProperty(BeanPropertyDefinition propDef) Method called by deserializer factory, when a "creator property" (something that is passed via constructor- or factory method argument; instead of setter or field).
void	addIgnorable(String propName) Method that will add property name as one of properties that can be ignored if not recognized.
void	addInjectable(String propertyName, JavaType propertyType, Annotations contextAnnotations, AnnotatedMember member, Object valueId)
void	addOrReplaceProperty(SettableBeanProperty prop, boolean allowOverride) Method for adding a new property or replacing a property.
void	addProperty(SettableBeanProperty prop) Method to add a property setter.
BeanDeserializer	build() Method for constructing a BeanDeserializer, given all information collected.
AbstractDeserializer	buildAbstract() Alternate build method used when we must be using some form of abstract resolution, usually by using addition Type Id ("polymorphic deserialization")
JsonDeserializer<?>	buildBuilderBased(JavaType valueType, String expBuildMethodName) Method for constructing a specialized deserializer that uses additional external Builder object during data binding.
SettableBeanProperty	findProperty(String propertyName)
SettableAnyProperty	getAnySetter()
JsonPOJOBuilder.Value	getBuilderConfig()
AnnotatedMethod	getBuildMethod()
List<ValueInjector>	getInjectables()
ObjectIdReader	getObjectIdReader()
Iterator<SettableBeanProperty>	getProperties() Method that allows accessing all properties that this builder currently contains.

Field Detail

_beanDesc

protected final BeanDescription _beanDesc

_defaultViewInclusion

protected final boolean _defaultViewInclusion

_properties

protected final Map<String,SettableBeanProperty> _properties

Properties to deserialize collected so far.

_injectables

protected List<ValueInjector> _injectables

Value injectors for deserialization

_backRefProperties

protected HashMap<String,SettableBeanProperty> _backRefProperties

Back-reference properties this bean contains (if any)

_ignorableProps

protected HashSet<String> _ignorableProps

Set of names of properties that are recognized but are to be ignored for deserialization purposes (meaning no exception is thrown, value is just skipped).

_valueInstantiator

protected ValueInstantiator _valueInstantiator

Object that will handle value instantiation for the bean type.

_objectIdReader

protected ObjectIdReader _objectIdReader

_anySetter

protected SettableAnyProperty _anySetter

Fallback setter used for handling any properties that are not mapped to regular setters. If setter is not null, it will be called once for each such property.

_ignoreAllUnknown

protected boolean _ignoreAllUnknown

Flag that can be set to ignore and skip unknown properties. If set, will not throw an exception for unknown properties.

_buildMethod

protected AnnotatedMethod _buildMethod

When creating Builder-based deserializers, this indicates method to call on builder to finalize value.

_builderConfig

protected JsonPOJOBuilder.Value _builderConfig

In addition, Builder may have additional configuration

Constructor Detail

BeanDeserializerBuilder

public BeanDeserializerBuilder(BeanDescription beanDesc,
                               DeserializationConfig config)

BeanDeserializerBuilder

protected BeanDeserializerBuilder(BeanDeserializerBuilder src)

Copy constructor for sub-classes to use, when constructing custom builder instances

Method Detail

addOrReplaceProperty

public void addOrReplaceProperty(SettableBeanProperty prop,
                                 boolean allowOverride)

Method for adding a new property or replacing a property.

addProperty

public void addProperty(SettableBeanProperty prop)

Method to add a property setter. Will ensure that there is no unexpected override; if one is found will throw a IllegalArgumentException.

addBackReferenceProperty

public void addBackReferenceProperty(String referenceName,
                                     SettableBeanProperty prop)

Method called to add a property that represents so-called back reference; reference that "points back" to object that has forward reference to currently built bean.

addInjectable

public void addInjectable(String propertyName,
                          JavaType propertyType,
                          Annotations contextAnnotations,
                          AnnotatedMember member,
                          Object valueId)

addIgnorable

public void addIgnorable(String propName)

Method that will add property name as one of properties that can be ignored if not recognized.

addCreatorProperty

public void addCreatorProperty(BeanPropertyDefinition propDef)

Method called by deserializer factory, when a "creator property" (something that is passed via constructor- or factory method argument; instead of setter or field).

Default implementation does not do anything; we may need to revisit this decision if these properties need to be available through accessors. For now, however, we just have to ensure that we don't try to resolve types that masked setter/field has (see [JACKSON-700] for details).

setAnySetter

public void setAnySetter(SettableAnyProperty s)

setIgnoreUnknownProperties

public void setIgnoreUnknownProperties(boolean ignore)

setValueInstantiator

public void setValueInstantiator(ValueInstantiator inst)

setObjectIdReader

public void setObjectIdReader(ObjectIdReader r)

setPOJOBuilder

public void setPOJOBuilder(AnnotatedMethod buildMethod,
                           JsonPOJOBuilder.Value config)

getProperties

public Iterator<SettableBeanProperty> getProperties()

Method that allows accessing all properties that this builder currently contains.

Note that properties are returned in order that properties are ordered (explictly, or by rule), which is the serialization order.

findProperty

public SettableBeanProperty findProperty(String propertyName)

hasProperty

public boolean hasProperty(String propertyName)

removeProperty

public SettableBeanProperty removeProperty(String name)

getAnySetter

public SettableAnyProperty getAnySetter()

getValueInstantiator

public ValueInstantiator getValueInstantiator()

getInjectables

public List<ValueInjector> getInjectables()

getObjectIdReader

public ObjectIdReader getObjectIdReader()

getBuildMethod

public AnnotatedMethod getBuildMethod()

getBuilderConfig

public JsonPOJOBuilder.Value getBuilderConfig()

build

public BeanDeserializer build()

Method for constructing a BeanDeserializer, given all information collected.

buildAbstract

public AbstractDeserializer buildAbstract()

Alternate build method used when we must be using some form of abstract resolution, usually by using addition Type Id ("polymorphic deserialization")

Since:

2.0

buildBuilderBased

public JsonDeserializer<?> buildBuilderBased(JavaType valueType,
                                             String expBuildMethodName)

Method for constructing a specialized deserializer that uses additional external Builder object during data binding.
