public abstract class AnnotationIntrospector extends Object implements Versioned, Serializable
Abstract class that defines API used for introspecting annotation-based configuration for serialization and deserialization. Separated so that different sets of annotations can be supported, and support plugged-in dynamically.

Although default implementations are based on using annotations as the only (or at least main) information source, custom implementations are not limited in such a way, and in fact there is no expectation they should be. So the name is bit of misnomer; this is a general configuration introspection facility.

NOTE: due to rapid addition of new methods (and changes to existing methods), it is strongly recommended that custom implementations should not directly extend this class, but rather extend NopAnnotationIntrospector. This way added methods will not break backwards compatibility of custom annotation introspectors.

    • nopInstance

      public static AnnotationIntrospector nopInstance()
      Factory method for accessing "no operation" implementation of introspector: instance that will never find any annotation-based configuration.

    • allIntrospectors

      public Collection<AnnotationIntrospector> allIntrospectors()
      Method that can be used to collect all "real" introspectors that this introspector contains, if any; or this introspector if it is not a container. Used to get access to all container introspectors in their priority order.

      Default implementation returns a Singleton list with this introspector as contents. This usually works for sub-classes, except for proxy or delegating "container introspectors" which need to override implementation.

      Returns:
      Collection of all introspectors starting with this one, in case multiple introspectors are chained
    • allIntrospectors

      Method that can be used to collect all "real" introspectors that this introspector contains, if any; or this introspector if it is not a container. Used to get access to all container introspectors in their priority order.

      Default implementation adds this introspector in result; this usually works for sub-classes, except for proxy or delegating "container introspectors" which need to override implementation.

      Parameters:
      result - Container to add introspectors to
      Returns:
      Passed in Collection filled with introspectors as explained above
    • version

      public abstract Version version()

      Returns:
      Version of the component
    • isAnnotationBundle

      public boolean isAnnotationBundle(Annotation ann)

      Parameters:
      ann - Annotated entity to introspect
      Returns:
      True if given annotation is considered an annotation bundle; false if not
    • findObjectIdInfo

      public ObjectIdInfo findObjectIdInfo(Annotated ann)

      Parameters:
      am - Annotated accessor (field/method/constructor parameter) to check for annotations
      Returns:
      Boolean to indicate whether member is a type id or not, if annotation found; null if no information found.

      public AnnotationIntrospector.ReferenceProperty findReferenceType(AnnotatedMember member)
      Method for checking if given member indicates that it is part of a reference (parent/child).
    • findUnwrappingNameTransformer

      public NameTransformer findUnwrappingNameTransformer(AnnotatedMember member)
      Method called to check whether given property is marked to be "unwrapped" when being serialized (and appropriately handled in reverse direction, i.e. expect unwrapped representation during deserialization). Return value is the name transformation to use, if wrapping/unwrapping should be done, or null if not -- note that transformation may simply be identity transformation (no changes).
    • hasIgnoreMarker

      public boolean hasIgnoreMarker(AnnotatedMember m)
      Method called to check whether given property is marked to be ignored. This is used to determine whether to ignore properties, on per-property basis, usually combining annotations from multiple accessors (getters, setters, fields, constructor parameters).
    • findInjectableValue

      public JacksonInject.Value findInjectableValue(AnnotatedMember m)
      Method called to find out whether given member expectes a value to be injected, and if so, what is the identifier of the value to use during injection. Type if identifier needs to be compatible with provider of values (of type InjectableValues); often a simple String id is used.
      Parameters:
      m - Member to check
      Returns:
      Identifier of value to inject, if any; null if no injection indicator is found
      Since:

    • hasRequiredMarker

      public Boolean hasRequiredMarker(AnnotatedMember m)
      Method that can be called to check whether this member has an annotation that suggests whether value for matching property is required or not.
    • findViews

      public Class<?>[] findViews(Annotated a)
      Method for checking if annotated property (represented by a field or getter/setter method) has definitions for views it is to be included in. If null is returned, no view definitions exist and property is always included (or always excluded as per default view inclusion configuration); otherwise it will only be included for views included in returned array. View matches are checked using class inheritance rules (sub-classes inherit inclusions of super-classes)

      Since 2.9 this method may also be called to find "default view(s)" for AnnotatedClass

      Parameters:
      a - Annotated property (represented by a method, field or ctor parameter)
      Returns:
      Array of views (represented by classes) that the property is included in; if null, always included (same as returning array containing Object.class)
    • findFormat

      public JsonFormat.Value findFormat(Annotated memberOrClass)
      Method for finding format annotations for property or class. Return value is typically used by serializers and/or deserializers to customize presentation aspects of the serialized value.
      Since:
      2.1
    • findWrapperName

      public PropertyName findWrapperName(Annotated ann)
      Method used to check if specified property has annotation that indicates that it should be wrapped in an element; and if so, name to use. Note that not all serializers and deserializers support use this method: currently (2.1) it is only used by XML-backed handlers.
      Returns:
      Wrapper name to use, if any, or PropertyName.USE_DEFAULT to indicate that no wrapper element should be used.
      Since:
      2.1
    • findPropertyDefaultValue

      public String findPropertyDefaultValue(Annotated ann)
      Method for finding suggested default value (as simple textual serialization) for the property. While core databind does not make any use of it, it is exposed for extension modules to use: an expected use is generation of schema representations and documentation.
      Since:
      2.5
    • findPropertyDescription

      public String findPropertyDescription(Annotated ann)
      Method used to check whether specified property member (accessor or mutator) defines human-readable description to use for documentation. There are no further definitions for contents; for example, whether these may be marked up using HTML is not defined.
      Returns:
      Human-readable description, if any.
      Since:
      2.3
    • findPropertyIndex

      public Integer findPropertyIndex(Annotated ann)
      Method used to check whether specified property member (accessor or mutator) defines numeric index, and if so, what is the index value. Possible use cases for index values included use by underlying data format (some binary formats mandate use of index instead of name) and ordering of properties (for documentation, or during serialization).
      Returns:
      Explicitly specified index for the property, if any
      Since:
      2.4
    • findImplicitPropertyName

      public String findImplicitPropertyName(AnnotatedMember member)
      Method for finding implicit name for a property that given annotated member (field, method, creator parameter) may represent. This is different from explicit, annotation-based property name, in that it is "weak" and does not either proof that a property exists (for example, if visibility is not high enough), or override explicit names. In practice this method is used to introspect optional names for creator parameters (which may or may not be available and cannot be detected by standard databind); or to provide alternate name mangling for fields, getters and/or setters.
      Since:
      2.4
    • findPropertyAliases

      public List<PropertyName> findPropertyAliases(Annotated ann)
      Method called to find if given property has alias(es) defined.
      Returns:
      `null` if member has no information; otherwise a `List` (possibly empty) of aliases to use.
      Since:
      2.9
    • findPropertyAccess

      public JsonProperty.Access findPropertyAccess(Annotated ann)
      Method for finding optional access definition for a property, annotated on one of its accessors. If a definition for read-only, write-only or read-write cases, visibility rules may be modified. Note, however, that even more specific annotations (like one for ignoring specific accessor) may further override behavior of the access definition.
      Since:
      2.6
    • resolveSetterConflict

      public AnnotatedMethod resolveSetterConflict(MapperConfig<?> config, AnnotatedMethod setter1, AnnotatedMethod setter2)
      Method called in cases where a class has two methods eligible to be used for the same logical property, and default logic is not enough to figure out clear precedence. Introspector may try to choose one to use; or, if unable, return `null` to indicate it cannot resolve the problem.
      Since:
      2.7
    • findRenameByField

      public PropertyName findRenameByField(MapperConfig<?> config, AnnotatedField f, PropertyName implName)
      Method called on fields that are eligible candidates for properties (that is, non-static member fields), but not necessarily selected (may or may not be visible), to let fields affect name linking. Call will be made after finding implicit name (which by default is just name of the field, but may be overridden by introspector), but before discovering other accessors. If non-null name returned, it is to be used to find other accessors (getters, setters, creator parameters) and replace their implicit names with that of field's implicit name (assuming they differ).

      Specific example (and initial use case is for support Kotlin's "is getter" matching (see Kotling Interop for details), in which field like 'isOpen' would have implicit name of "isOpen", match getter getOpen() and setter setOpen(boolean), but use logical external name of "isOpen" (and not implicit name of getter/setter, "open"!). To achieve this, field implicit name needs to remain "isOpen" but this method needs to return name PropertyName.construct("open"): doing so will "pull in" getter and/or setter, and rename them as "isOpen".

      Parameters:
      config - Effective mapper configuration in use
      f - Field to check
      implName - Implicit name of the field; usually name of field itself but not always, used as the target name for accessors to rename.
      Returns:
      Name used to find other accessors to rename, if any; null to indicate no renaming
      Since:
      2.11

    • findSerializer

      public Object findSerializer(Annotated am)
      Method for getting a serializer definition on specified method or field. Type of definition is either instance (of type JsonSerializer) or Class (of Class<JsonSerializer> implementation subtype); if value of different type is returned, a runtime exception may be thrown by caller.
    • findKeySerializer

      public Object findKeySerializer(Annotated am)
      Method for getting a serializer definition for keys of associated java.util.Map property. Type of definition is either instance (of type JsonSerializer) or Class (of type Class<JsonSerializer>); if value of different type is returned, a runtime exception may be thrown by caller.
    • findContentSerializer

      public Object findContentSerializer(Annotated am)
      Method for getting a serializer definition for content (values) of associated Collection, array or Map property. Type of definition is either instance (of type JsonSerializer) or Class (of type Class<JsonSerializer>); if value of different type is returned, a runtime exception may be thrown by caller.

      2.3
    • findSerializationTyping

      public JsonSerialize.Typing findSerializationTyping(Annotated a)
      Method for accessing declared typing mode annotated (if any). This is used for type detection, unless more granular settings (such as actual exact type; or serializer to use which means no type information is needed) take precedence.
      Returns:
      Typing mode to use, if annotation is found; null otherwise
    • findSerializationConverter

      public Object findSerializationConverter(Annotated a)
      Method for finding Converter that annotated entity (property or class) has indicated to be used as part of serialization. If not null, either has to be actual Converter instance, or class for such converter; and resulting converter will be used first to convert property value to converter target type, and then serializer for that type is used for actual serialization.

      This feature is typically used to convert internal values into types that Jackson can convert.

      Note also that this feature does not necessarily work well with polymorphic type handling, or object identity handling; if such features are needed an explicit serializer is usually better way to handle serialization.

      Parameters:
      a - Annotated property (field, method) or class to check for annotations
      Since:
      2.2
    • findSerializationContentConverter

      public Object findSerializationContentConverter(AnnotatedMember a)
      Method for finding Converter that annotated property has indicated needs to be used for values of container type (this also means that method should only be called for properties of container types, List/Map/array properties).

      If not null, either has to be actual Converter instance, or class for such converter; and resulting converter will be used first to convert property value to converter target type, and then serializer for that type is used for actual serialization.

      Other notes are same as those for findSerializationConverter(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.introspect.Annotated)

      Parameters:
      a - Annotated property (field, method) to check.

    • findPropertyInclusion

      public JsonInclude.Value findPropertyInclusion(Annotated a)
      Method for checking inclusion criteria for a type (Class) or property (yes, method name is bit unfortunate -- not just for properties!). In case of class, acts as the default for properties POJO contains; for properties acts as override for class defaults and possible global defaults.
      Since:
      2.6
    • findSerializationInclusion

      @Deprecated public JsonInclude.Include findSerializationInclusion(Annotated a, JsonInclude.Include defValue)
      Method for checking whether given annotated entity (class, method, field) defines which Bean/Map properties are to be included in serialization. If no annotation is found, method should return given second argument; otherwise value indicated by the annotation.

      Note that meaning of inclusion value depends on whether it is for a Class or property (field/method/constructor): in former case, it is the default for all properties; in latter case it is specific override for annotated property.

      Returns:
      Enumerated value indicating which properties to include in serialization
    • findSerializationInclusionForContent

      @Deprecated public JsonInclude.Include findSerializationInclusionForContent(Annotated a, JsonInclude.Include defValue)
      Method for checking whether content (entries) of a Map property are to be included during serialization or not. NOTE: this is NOT called for POJO properties, or array/Collection elements.

      Method that is related to findEnumValues(java.lang.Class<?>, java.lang.Enum<?>[], java.lang.String[]) but is called to check if there are alternative names (aliased) that can be accepted for entries, in addition to primary names introspected earlier. If so, these aliases should be returned in aliases List passed as argument (and initialized for proper size by caller).
      Parameters:

    • findEnumValue

      @Deprecated public String findEnumValue(Enum<?> value)
      Deprecated.
      Since 2.8: use findEnumValues(java.lang.Class<?>, java.lang.Enum<?>[], java.lang.String[]) instead because this method does not properly handle override settings (defaults to enum.name without indicating whether that is explicit or not), and is inefficient to call one-by-one.
      Method for determining the String value to use for serializing given enumeration entry; used when serializing enumerations as Strings (the standard method).
      Parameters:
      value - Enum value to introspect

    • findContentDeserializer

      public Object findContentDeserializer(Annotated am)
      Method for getting a deserializer definition for content (values) of associated Collection, array or Map property.

    • findDeserializationConverter

      public Object findDeserializationConverter(Annotated a)
      Method for finding Converter that annotated entity (property or class) has indicated to be used as part of deserialization. If not null, either has to be actual Converter instance, or class for such converter; and resulting converter will be used after Jackson has deserializer data into intermediate type (Converter input type), and Converter needs to convert this into its target type to be set as property value.

      This feature is typically used to convert intermediate Jackson types (that default deserializers can produce) into custom type instances.

      Note also that this feature does not necessarily work well with polymorphic type handling, or object identity handling; if such features are needed an explicit deserializer is usually better way to handle deserialization.

      Parameters:
      a - Annotated property (field, method) or class to check for annotations
      Since:
      2.2
    • findDeserializationContentConverter

      public Object findDeserializationContentConverter(AnnotatedMember a)
      Method for finding Converter that annotated property has indicated needs to be used for values of container type (this also means that method should only be called for properties of container types, List/Map/array properties).

      If not null, either has to be actual Converter instance, or class for such converter; and resulting converter will be used after Jackson has deserializer data into intermediate type (Converter input type), and Converter needs to convert this into its target type to be set as property value.

      Other notes are same as those for findDeserializationConverter(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.introspect.Annotated)

      Parameters:
      a - Annotated property (field, method) to check.

      @Deprecated public Class<?> findDeserializationType(Annotated ann, JavaType baseType)
      Method for accessing annotated type definition that a property can have, to be used as the type for deserialization instead of the static (declared) type. Type is usually narrowing conversion (i.e.subtype of declared type). Declared return type of the method is also considered acceptable.
      Parameters:
      ann - Annotated entity to introspect
      baseType - Assumed type before considering annotations
      Returns:
      Class to use for deserialization instead of declared type

      Parameters:
      ann - Annotated entity to introspect
      baseKeyType - Assumed key type before considering annotations
      Returns:
      Class specifying more specific type to use instead of declared type, if annotation found; null if not
    • findDeserializationContentType

      @Deprecated public Class<?> findDeserializationContentType(Annotated ann, JavaType baseContentType)
      Method for accessing additional narrowing type definition that a method can have, to define more specific content type to use; content refers to Map values and Collection/array elements. It should be only be used with Map, Collection and array types.
      Parameters:
      ann - Annotated entity to introspect
      baseContentType - Assumed content (value) type before considering annotations
      Returns:
      Class specifying more specific type to use instead of declared type, if annotation found; null if not
    • findValueInstantiator

      public Object findValueInstantiator(AnnotatedClass ac)
      Method getting ValueInstantiator to use for given type (class): return value can either be an instance of instantiator, or class of instantiator to create.
      Parameters:
      ac - Annotated class to introspect
      Returns:
      Either ValueInstantiator instance to use, or Class of one to create; or null if no annotations found to indicate custom value instantiator.
    • findPOJOBuilder

      public Class<?> findPOJOBuilder(AnnotatedClass ac)
      Method for finding Builder object to use for constructing value instance and binding data (sort of combining value instantiators that can construct, and deserializers that can bind data).

      Note that unlike accessors for some helper Objects, this method does not allow returning instances: the reason is that builders have state, and a separate instance needs to be created for each deserialization call.

      Parameters:
      ac - Annotated class to introspect
      Returns:
      Builder class to use, if annotation found; null if not.
      Since:

      public JsonCreator.Mode findCreatorAnnotation(MapperConfig<?> config, Annotated ann)
      Method called to check whether potential Creator (constructor or static factory method) has explicit annotation to indicate it as actual Creator; and if so, which JsonCreator.Mode to use.

      NOTE: caller needs to consider possibility of both `null` (no annotation found) and JsonCreator.Mode.DISABLED (annotation found, but disabled); latter is necessary as marker in case multiple introspectors are chained, as well as possibly as when using mix-in annotations.

      Parameters:
      config - Configuration settings in effect (for serialization or deserialization)
      ann - Annotated accessor (usually constructor or static method) to check
