```
    Description copied from class: AnnotationIntrospector
    
    Method for checking if annotations indicate changes to minimum visibility levels needed for auto-detecting property elements (fields, methods, constructors). A baseline checker is given, and introspector is to either return it as is (if no annotations are found), or build and return a derived instance (using checker's build methods).

    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 class AnnotationIntrospector

```
public List<PropertyName> findPropertyAliases(Annotated m)

  - hasRequiredMarker
```
public Boolean hasRequiredMarker(AnnotatedMember m)

    Overrides:
    
    hasRequiredMarker in class AnnotationIntrospector
  - findPropertyAccess
```
public JsonProperty.Access findPropertyAccess(Annotated m)
```
    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 class AnnotationIntrospector
  - findPropertyDescription
```
public 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:
    
    findPropertyDescription in class AnnotationIntrospector
    
    Returns:
    
    Human-readable description, if any.
  - findPropertyIndex
```
public 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 class AnnotationIntrospector
    
    Returns:
    
    Explicitly specified index for the property, if any
  - findPropertyDefaultValue
```
public String findPropertyDefaultValue(Annotated ann)
```
    Description copied from class: AnnotationIntrospector
    
    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 class AnnotationIntrospector
  - findFormat
```
public JsonFormat.Value findFormat(Annotated ann)
```

```
    Description copied from class: AnnotationIntrospector
    
    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).
    
    Overrides:
    
    findUnwrappingNameTransformer in class AnnotationIntrospector
  - findInjectableValue
```
public JacksonInject.Value findInjectableValue(AnnotatedMember m)
```
    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    findInjectableValue in class AnnotationIntrospector
    
    Parameters:
    
    m - Member 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)
    Since 2.9 this method may also be called to find "default view(s)" for AnnotatedClass
    
    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)
  - resolveSetterConflict

```
    Specific implementation that will use following tie-breaker on given setter parameter types:
    1. If either one is primitive type then either return null (both primitives) or one that is primitive (when only primitive)
    2. If only one is of type String, return that setter
    3. Otherwise return null
    Returning null will indicate that resolution could not be done.
    Overrides:
    
    resolveSetterConflict in class AnnotationIntrospector
  - 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 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".
    
    Overrides:
    
    findRenameByField in class AnnotationIntrospector
    
    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

```
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.
    
    Overrides:
    
    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.

  - findDeserializer
```
public Object 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&<JsonDeserializer>); type is returned, a runtime exception may be thrown by caller.
    
    Overrides:
    
    findDeserializer in class AnnotationIntrospector
  - findKeyDeserializer
```
public Object 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<JsonDeserializer>); if value of different type is returned, a runtime exception may be thrown by caller.
    
    Overrides:
    
    findKeyDeserializer in class AnnotationIntrospector
  - findContentDeserializer
```
public Object findContentDeserializer(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    Method for getting a deserializer definition for content (values) of associated Collection, array or Map property. Type of definition is either instance (of type JsonDeserializer) or Class (of type Class<JsonDeserializer>); if value of different type is returned, a runtime exception may be thrown by caller.
    
    Overrides:
    
    findContentDeserializer in class AnnotationIntrospector
  - 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.
    Other notes are same as those for AnnotationIntrospector.findDeserializationConverter(com.fasterxml.jackson.databind.introspect.Annotated)

```
    Deprecated.
    
    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
    
    Parameters:
    
    am - Annotated entity to introspect
    
    baseContentType - Assumed content (value) type before considering annotations

    Deprecated.
    
    Description copied from class: AnnotationIntrospector
    
    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.

    findDeserializationType in class AnnotationIntrospector
    
    Parameters:
    
    am - Annotated entity to introspect

    Overrides:
    
    findDeserializationKeyType in class AnnotationIntrospector
    
    Parameters:
    
    am - Annotated entity to introspect
    
    baseKeyType - Assumed key type before considering annotations

```
public Object findValueInstantiator(AnnotatedClass ac)
```
    Description copied from class: AnnotationIntrospector
    
    Method getting ValueInstantiator to use for given type (class): return value can either be an instance of instantiator, or class of instantiator to create.
    
    Overrides:
    
    findValueInstantiator in class AnnotationIntrospector
    
    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)
```
    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
    
    Parameters:
    
    ac - Annotated class to introspect

    Overrides:
    
    findPOJOBuilderConfig in class AnnotationIntrospector
    
    Parameters:
    
    ac - Annotated class to introspect

  - findNameForDeserialization
```
public PropertyName findNameForDeserialization(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 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 - Annotated entity to check

    Overrides:
    
    hasCreatorAnnotation in class AnnotationIntrospector
    
    Parameters:
    
    a - Annotated entity to check
    
    Returns:
    
    True if such annotation is found (and is not disabled), false otherwise
  - findCreatorBinding
```
@Deprecated
public JsonCreator.Mode findCreatorBinding(Annotated a)
```
    Deprecated.
    
    Description copied from class: AnnotationIntrospector
    
    Method for finding indication of creator binding mode for a creator (something for which AnnotationIntrospector.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).

    Description copied from class: AnnotationIntrospector
    
    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.
    
    Overrides:
    
    findCreatorAnnotation in class AnnotationIntrospector
    
    Parameters:
