Field Detail

_config

protected final MapperConfig<?> _config

Configuration settings

_accessorNaming

protected final AccessorNamingStrategy _accessorNaming

Handler used for name-mangling of getter, mutator (setter/with) methods

Since:

2.12

_forSerialization

protected final boolean _forSerialization

True if introspection is done for serialization (giving precedence for serialization annotations), or not (false, deserialization)

_type

protected final JavaType _type

Type of POJO for which properties are being collected.

_classDef

protected final AnnotatedClass _classDef

Low-level introspected class information (methods, fields etc)

_visibilityChecker

protected final VisibilityChecker<?> _visibilityChecker

_annotationIntrospector

protected final AnnotationIntrospector _annotationIntrospector

_useAnnotations

protected final boolean _useAnnotations

Since:

2.9

_collected

protected boolean _collected

State flag we keep to indicate whether actual property information has been collected or not.

_properties

protected LinkedHashMap<String,POJOPropertyBuilder> _properties

Set of logical property information collected so far.

Since 2.6, this has been constructed (more) lazily, to defer throwing of exceptions for potential conflicts in cases where this may not be an actual problem.

_creatorProperties

protected LinkedList<POJOPropertyBuilder> _creatorProperties

_fieldRenameMappings

protected Map<PropertyName,PropertyName> _fieldRenameMappings

A set of "field renamings" that have been discovered, indicating intended renaming of other accesors: key is the implicit original name and value intended name to use instead.

Note that these renamings are applied earlier than "regular" (explicit) renamings and affect implicit name: their effect may be changed by further renaming based on explicit indicators. The main use case is to effectively relink accessors based on fields discovered, and used to sort of correct otherwise missing linkage between fields and other accessors.

Since:

2.11

_anyGetters

protected LinkedList<AnnotatedMember> _anyGetters

_anyGetterField

protected LinkedList<AnnotatedMember> _anyGetterField

Since:

2.12

_anySetters

protected LinkedList<AnnotatedMethod> _anySetters

_anySetterField

protected LinkedList<AnnotatedMember> _anySetterField

_jsonKeyAccessors

protected LinkedList<AnnotatedMember> _jsonKeyAccessors

Accessors (field or "getter" method annotated with JsonKey

Since:

2.12

_jsonValueAccessors

protected LinkedList<AnnotatedMember> _jsonValueAccessors

Accessors (field or "getter" method) annotated with JsonValue

_ignoredPropertyNames

protected HashSet<String> _ignoredPropertyNames

Lazily collected list of properties that can be implicitly ignored during serialization; only updated when collecting information for deserialization purposes

_injectables

protected LinkedHashMap<Object,AnnotatedMember> _injectables

Lazily collected list of members that were annotated to indicate that they represent mutators for deserializer value injection.

_stdBeanNaming

@Deprecated
protected final boolean _stdBeanNaming

Deprecated. Since 2.12

_mutatorPrefix

@Deprecated
protected String _mutatorPrefix

Deprecated. Since 2.12
