public JsonSerialize.Typing findSerializationTyping(Annotated a)
```
    Description copied from class: AnnotationIntrospector

public Object findSerializationConverter(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    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.

    findSerializationConverter in class AnnotationIntrospector
    
    Parameters:
    a - Annotated property (field, method) or class to check for annotations

public Object findSerializationContentConverter(AnnotatedMember a)
```
    Description copied from class: AnnotationIntrospector
    
    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 AnnotationIntrospector.findSerializationConverter(com.fasterxml.jackson.databind.introspect.Annotated)
    
    Overrides:
    
    findSerializationContentConverter in class AnnotationIntrospector
    
    Parameters:
    a - Annotated property (field, method) to check.
  - findViews
```
public 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)
    
    Overrides:
    
    findViews in class AnnotationIntrospector
    
    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)
  - isTypeId
```
public Boolean isTypeId(AnnotatedMember member)
```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given accessor claims to represent type id: if so, its value may be used as an override, instead of generated type id.
    
    Overrides:
    
    isTypeId in class AnnotationIntrospector
  - findObjectIdInfo
```
public ObjectIdInfo findObjectIdInfo(Annotated ann)
```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given annotated thing (type, or accessor) indicates that values referenced (values of type of annotated class, or values referenced by annotated property; latter having precedence) should include Object Identifier, and if so, specify details of Object Identity used.
    
    Overrides:
    
    findObjectIdInfo in class AnnotationIntrospector
  - findObjectReferenceInfo
```
public ObjectIdInfo findObjectReferenceInfo(Annotated ann,
                                   ObjectIdInfo objectIdInfo)
```
    Description copied from class: AnnotationIntrospector
    
    Method for figuring out additional properties of an Object Identity reference
    
    Overrides:
    
    findObjectReferenceInfo in class AnnotationIntrospector
  - findFormat
```
public JsonFormat.Value findFormat(Annotated annotated)
```
    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    findFormat in class AnnotationIntrospector
  - findPropertyDescription
```
public String findPropertyDescription(Annotated annotated)
```
    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:
    
    findPropertyDescription in class AnnotationIntrospector
    
    Returns:
    Human-readable description, if any.
  - findPropertyIndex
```
public Integer findPropertyIndex(Annotated annotated)
```
    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 class AnnotationIntrospector
    
    Returns:
    Explicitly specified index for the property, if any
  - findImplicitPropertyName
```
public String findImplicitPropertyName(AnnotatedMember param)
```
    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 can not be detected by standard databind); or to provide alternate name mangling for fields, getters and/or setters.
    
    Overrides:
    
    findImplicitPropertyName in class AnnotationIntrospector
  - findSerializationPropertyOrder
```
public String[] findSerializationPropertyOrder(AnnotatedClass ac)
```
    Description copied from class: AnnotationIntrospector

    Overrides:
    
    findSerializationPropertyOrder in class AnnotationIntrospector
  - findSerializationSortAlphabetically
```
public Boolean findSerializationSortAlphabetically(Annotated ann)
```
    Description copied from class: AnnotationIntrospector

    Overrides:
    
    findSerializationSortAlphabetically in class AnnotationIntrospector
  - findSerializationSortAlphabetically
```
@Deprecated
public Boolean findSerializationSortAlphabetically(AnnotatedClass ac)
```

    findSerializationSortAlphabetically in class AnnotationIntrospector
  - findNameForSerialization
```
public PropertyName findNameForSerialization(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given property accessors (method, field) has an annotation that suggests property name to use for serialization. Should return null if no annotation is found; otherwise a non-null name (possibly PropertyName.USE_DEFAULT, which means "use default heuristics").
    
    Overrides:
    
    findNameForSerialization in class AnnotationIntrospector
    
    Parameters:
    a - Property accessor to check
    
    Returns:
    Name to use if found; null if not.
  - hasAsValueAnnotation
```
public boolean hasAsValueAnnotation(AnnotatedMethod am)
```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given method has an annotation that suggests that the return value of annotated method should be used as "the value" of the object instance; usually serialized as a primitive value such as String or number.
    
    Overrides:
    
    hasAsValueAnnotation in class AnnotationIntrospector
    
    Returns:
    True if such annotation is found (and is not disabled); false if no enabled annotation is found

```
public Class<? extends JsonDeserializer<?>> findDeserializer(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    Method for getting a deserializer definition on specified method or field. Type of definition is either instance (of type JsonDeserializer) or Class (of type Class); if value of different type is returned, a runtime exception may be thrown by caller.
    
    Overrides:
    
    findDeserializer in class AnnotationIntrospector
  - findKeyDeserializer
```
public Class<? extends KeyDeserializer> findKeyDeserializer(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    Method for getting a deserializer definition for keys of associated Map property. Type of definition is either instance (of type JsonDeserializer) or Class (of type Class); if value of different type is returned, a runtime exception may be thrown by caller.

```
    Description copied from class: AnnotationIntrospector
    
    Method for accessing annotated type definition that a method can have, to be used as the type for serialization instead of the runtime type. Type must be a narrowing conversion (i.e.subtype of declared type). Declared return type of the method is also considered acceptable.
    
    Overrides:
    
    findDeserializationType in class AnnotationIntrospector
    
    baseType - Assumed type before considering annotations
    
    Returns:
    Class to use for deserialization instead of declared type
  - findDeserializationKeyType
```
public Class<?> findDeserializationKeyType(Annotated am,
                                  JavaType baseKeyType)
```
    Description copied from class: AnnotationIntrospector
    
    Method for accessing additional narrowing type definition that a method can have, to define more specific key type to use. It should be only be used with Map types.
    
    Overrides:
    
    findDeserializationKeyType in class AnnotationIntrospector
    
    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
```
public Class<?> findDeserializationContentType(Annotated am,
                                      JavaType baseContentType)
```
    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    findDeserializationContentType in class AnnotationIntrospector
    
    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
  - findDeserializationConverter
```
public Object findDeserializationConverter(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    findDeserializationConverter in class AnnotationIntrospector
    
    Parameters:
    a - Annotated property (field, method) or class to check for annotations
  - findDeserializationContentConverter
```
public Object findDeserializationContentConverter(AnnotatedMember a)
```
    Description copied from class: AnnotationIntrospector
    
    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.

    Overrides:
    
    findValueInstantiator in class AnnotationIntrospector
  - findPOJOBuilder
```
public Class<?> findPOJOBuilder(AnnotatedClass ac)
```
    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    findPOJOBuilder in class AnnotationIntrospector
  - findPOJOBuilderConfig
```
public JsonPOJOBuilder.Value findPOJOBuilderConfig(AnnotatedClass ac)

```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given property accessors (method, field) has an annotation that suggests property name to use for deserialization (reading JSON into POJOs). Should return null if no annotation is found; otherwise a non-null name (possibly PropertyName.USE_DEFAULT, which means "use default heuristics").
    
    Overrides:
    
    findNameForDeserialization in class AnnotationIntrospector
    
    Parameters:
    a - Property accessor to check
    
    Returns:

    Overrides:
    
    hasAnyGetterAnnotation in class AnnotationIntrospector
    
    Returns:
    True if such annotation is found (and is not disabled), false otherwise
  - hasCreatorAnnotation
```
public boolean hasCreatorAnnotation(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    hasCreatorAnnotation in class AnnotationIntrospector
    
    Returns:
    True if such annotation is found (and is not disabled), false otherwise
