XmlAnnotationIntrospector.Pair
public class AnnotationIntrospectorPair extends AnnotationIntrospector implements java.io.Serializable
Helper class that allows using 2 introspectors such that one introspector acts as the primary one to use; and second one as a fallback used if the primary does not provide conclusive or useful result for a method.An obvious consequence of priority is that it is easy to construct longer chains of introspectors by linking multiple pairs. Currently most likely combination is that of using the default Jackson provider, along with JAXB annotation introspector.
Note: up until 2.0, this class was an inner class of
AnnotationIntrospector
; moved here for convenience.- Since:

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.
- Overrides:
findSerializationInclusion
in classAnnotationIntrospector
- Returns:
- Enumerated value indicating which properties to include in serialization
-
findSerializationInclusionForContent
@Deprecated public JsonInclude.Include findSerializationInclusionForContent(Annotated a, JsonInclude.Include defValue)
Deprecated.Description copied from class:AnnotationIntrospector
Method for checking whether content (entries) of aMap
property are to be included during serialization or not. NOTE: this is NOT called for POJO properties, or array/Collection elements.- Overrides:
findSerializationInclusionForContent
in classAnnotationIntrospector
-
findPropertyInclusion
public JsonInclude.Value findPropertyInclusion(Annotated a)
Description copied from class:AnnotationIntrospector
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.- Overrides:
findPropertyInclusion
in classAnnotationIntrospector
-
findSerializationTyping
public JsonSerialize.Typing findSerializationTyping(Annotated a)
Description copied from class:AnnotationIntrospector
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.- Overrides:
findSerializationTyping
in classAnnotationIntrospector
- Returns:
- Typing mode to use, if annotation is found; null otherwise
-
findSerializationConverter
public java.lang.Object findSerializationConverter(Annotated a)
Description copied from class:AnnotationIntrospector
Method for findingConverter
that annotated entity (property or class) has indicated to be used as part of serialization. If not null, either has to be actualConverter
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.
- Overrides:
findSerializationConverter
in classAnnotationIntrospector
- Parameters:
a
- Annotated property (field, method) or class to check for annotations
-
findSerializationContentConverter
public java.lang.Object findSerializationContentConverter(AnnotatedMember a)
Description copied from class:AnnotationIntrospector
Method for findingConverter
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
AnnotationIntrospector.findSerializationConverter(com.fasterxml.jackson.databind.introspect.Annotated)
- Overrides:
findSerializationContentConverter
in classAnnotationIntrospector
- Parameters:
a
- Annotated property (field, method) to check.
-
findViews
public java.lang.Class<?>[] findViews(Annotated a)
Description copied from class:AnnotationIntrospector
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
- Overrides:
findViews
in classAnnotationIntrospector
- 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
)

PropertyName.USE_DEFAULT
to indicate that no wrapper element should be used.
-
findPropertyDefaultValue
public java.lang.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.- Overrides:
findPropertyDefaultValue
in classAnnotationIntrospector
-
findPropertyDescription
public java.lang.String findPropertyDescription(Annotated ann)
Description copied from class:AnnotationIntrospector
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.- Overrides:

-
findPropertyIndex
public java.lang.Integer findPropertyIndex(Annotated ann)
Description copied from class:AnnotationIntrospector
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).- Overrides:
findPropertyIndex
in classAnnotationIntrospector

-
findImplicitPropertyName
public java.lang.String findImplicitPropertyName(AnnotatedMember ann)
Description copied from class:AnnotationIntrospector
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.- Overrides:
findImplicitPropertyName
in classAnnotationIntrospector
-
findPropertyAliases

- Returns:
- `null` if member has no information; otherwise a `List` (possibly empty) of aliases to use.
-
findPropertyAccess
public JsonProperty.Access findPropertyAccess(Annotated ann)
Description copied from class:AnnotationIntrospector
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.- Overrides:
findPropertyAccess
in classAnnotationIntrospector
-
resolveSetterConflict
public AnnotatedMethod resolveSetterConflict(MapperConfig<?> config, AnnotatedMethod setter1, AnnotatedMethod setter2)
Description copied from class:AnnotationIntrospector
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.- Overrides:
resolveSetterConflict
in classAnnotationIntrospector
-
findRenameByField
public PropertyName findRenameByField(MapperConfig<?> config, AnnotatedField f, PropertyName implName)
Description copied from class:AnnotationIntrospector
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 gettergetOpen()
and settersetOpen(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 namePropertyName.construct("open")
: doing so will "pull in" getter and/or setter, and rename them as "isOpen".- Overrides:
findRenameByField
in classAnnotationIntrospector
- Parameters:
config
- Effective mapper configuration in usef
- Field to checkimplName
- 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
