```
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.

    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

  - 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.

                                             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.

  - 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.
  - findNullSerializer
```
public Object findNullSerializer(Annotated am)
```
    Method for getting a serializer definition for serializer to use for nulls (null values) of associated property or type.

    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(com.fasterxml.jackson.databind.introspect.Annotated)

  - 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.

```
    Deprecated. Since 2.7 Use findPropertyInclusion(com.fasterxml.jackson.databind.introspect.Annotated) instead
    
    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

```
    Method for efficiently figuring out which if given set of Enum values have explicitly defined name. Method will overwrite entries in incoming names array with explicit names found, if any, leaving other entries unmodified.
    Default implementation will simply delegate to findEnumValue(java.lang.Enum<?>), which is close enough, although unfortunately NOT 100% equivalent (as it will also consider name() to give explicit value).

  - 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.

    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)
    
    a - Annotated accessor (usually constructor or static method) to check
    
    Since:
    
    2.9
  - hasCreatorAnnotation
```
@Deprecated
public boolean hasCreatorAnnotation(Annotated a)
```
    Deprecated. Since 2.9 use findCreatorAnnotation(com.fasterxml.jackson.databind.cfg.MapperConfig<?>, com.fasterxml.jackson.databind.introspect.Annotated) instead.
    
    Method for checking whether given annotated item (method, constructor) has an annotation that suggests that the method is a "creator" (aka factory) method to be used for construct new instances of deserialized values.
    
    Returns:
    
    True if such annotation is found (and is not disabled), false otherwise
  - findCreatorBinding
```
@Deprecated
public JsonCreator.Mode findCreatorBinding(Annotated a)
```
    Deprecated. Since 2.9 use findCreatorAnnotation(com.fasterxml.jackson.databind.cfg.MapperConfig<?>, com.fasterxml.jackson.databind.introspect.Annotated) instead.
    
    Method for finding indication of creator binding mode for a creator (something for which hasCreatorAnnotation(com.fasterxml.jackson.databind.introspect.Annotated) returns true), for cases where there may be ambiguity (currently: single-argument creator with implicit but no explicit name for the argument).
    
    Since:
    
    2.5
  - hasAnySetterAnnotation
```
@Deprecated
public boolean hasAnySetterAnnotation(AnnotatedMethod am)
```
    Deprecated. Since 2.9 use hasAnySetter(com.fasterxml.jackson.databind.introspect.Annotated) instead.
  - _findAnnotation
```
protected <A extends Annotation> A _findAnnotation(Annotated annotated,
                                                   Class<A> annoClass)
```
    Method that should be used by sub-classes for ALL annotation access; overridable so that sub-classes may, if they choose to, mangle actual access to block access ("hide" annotations) or perhaps change it.
    Default implementation is simply: return annotated.getAnnotation(annoClass);
    
    Since:
    
    2.5
  - _hasAnnotation
```
protected boolean _hasAnnotation(Annotated annotated,
                                 Class<? extends Annotation> annoClass)
```
    Method that should be used by sub-classes for ALL annotation existence access; overridable so that sub-classes may, if they choose to, mangle actual access to block access ("hide" annotations) or perhaps change value seen.
    Default implementation is simply: return annotated.hasAnnotation(annoClass);
    
    Since:
    
    2.5
  - _hasOneOf
```
protected boolean _hasOneOf(Annotated annotated,
                            Class<? extends Annotation>[] annoClasses)
```
    Alternative lookup method that is used to see if annotation has at least one of annotations of types listed in second argument.
    
    Since:
    
    2.7
