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

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

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

_isIgnorable

protected boolean _isIgnorable(Annotated a)

_findTypeResolver

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

Helper method called to construct and initialize instance of TypeResolverBuilder if given annotated element indicates one is needed.

_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)
