public Class<?> findDeserializationType(Annotated am,
                               JavaType baseType)

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.

Other notes are same as those for AnnotationIntrospector.findDeserializationConverter(com.fasterxml.jackson.databind.introspect.Annotated)

Overrides:

findDeserializationContentConverter in class AnnotationIntrospector

Parameters:

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

findValueInstantiator

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

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)

Overrides:

findPOJOBuilderConfig in class AnnotationIntrospector

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 - Property accessor to check

Returns:

Name to use if found; null if not.

findDeserializationName

public String findDeserializationName(AnnotatedMethod am)

Description copied from class: AnnotationIntrospector

Method for checking whether given method has an annotation that suggests property name associated with method that may be a "setter". Should return null if no annotation is found; otherwise a non-null String. If non-null value is returned, it is used as the property name, except for empty String ("") which is taken to mean "use standard bean name detection if applicable; method name if not".

Overrides:

findDeserializationName in class AnnotationIntrospector

findDeserializationName

public String findDeserializationName(AnnotatedField af)

Description copied from class: AnnotationIntrospector

Method for checking whether given member field represent a deserializable logical property; and if so, returns the name of that property. Should return null if no annotation is found (indicating it is not a deserializable field); otherwise a non-null String. If non-null value is returned, it is used as the property name, except for empty String ("") which is taken to mean "use the field name as is".

Overrides:

findDeserializationName in class AnnotationIntrospector

findDeserializationName

public String findDeserializationName(AnnotatedParameter param)

Description copied from class: AnnotationIntrospector

Method for checking whether given set of annotations indicates property name for associated parameter. No actual parameter object can be passed since JDK offers no representation; just annotations.

Overrides:

findDeserializationName in class AnnotationIntrospector

hasAnySetterAnnotation

public boolean hasAnySetterAnnotation(AnnotatedMethod am)

Description copied from class: AnnotationIntrospector

Method for checking whether given method has an annotation that suggests that the method is to serve as "any setter"; method to be used for setting values of any properties for which no dedicated setter method is found.

Overrides:

hasAnySetterAnnotation in class AnnotationIntrospector

Returns:

True if such annotation is found (and is not disabled), false otherwise

hasAnyGetterAnnotation

public boolean hasAnyGetterAnnotation(AnnotatedMethod am)

Description copied from class: AnnotationIntrospector

Method for checking whether given method has an annotation that suggests that the method is to serve as "any setter"; method to be used for accessing set of miscellaneous "extra" properties, often bound with matching "any setter" method.

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

_isIgnorable

protected boolean _isIgnorable(Annotated a)

_findTypeResolver

protected TypeResolverBuilder<?> _findTypeResolver(MapperConfig<?> config,
                                       Annotated ann,
                                       JavaType baseType)

_constructStdTypeResolverBuilder

protected StdTypeResolverBuilder _constructStdTypeResolverBuilder()

Helper method for constructing standard TypeResolverBuilder implementation.

_constructNoTypeResolverBuilder

protected StdTypeResolverBuilder _constructNoTypeResolverBuilder()

Helper method for dealing with "no type info" marker; can't be null (as it'd be replaced by default typing)
