s. Same can not be done with 2.10 for backwards-compatibility
reasons; but we can offer sort of "fake" builder, which simply encapsulates
configuration calls. The main (and only) point is to allow gradual upgrade.Modifier | Constructor and Description |

B |
activateDefaultTyping(PolymorphicTypeValidator subtypeValidator,
ObjectMapper.DefaultTyping applicability,
JsonTypeInfo.As includeAs)
Method for enabling automatic inclusion of type information, needed
for proper deserialization of polymorphic types (unless types
have been annotated with
JsonTypeInfo ). |
B |
activateDefaultTypingAsProperty(PolymorphicTypeValidator subtypeValidator,
ObjectMapper.DefaultTyping applicability,
String propertyName)
Method for enabling automatic inclusion of type information -- needed
for proper deserialization of polymorphic types (unless types
have been annotated with
JsonTypeInfo ) --
using "As.PROPERTY" inclusion mechanism and specified property name
to use for inclusion (default being "@class" since default type information
always uses class name as type identifier) |
B |
addHandler(DeserializationProblemHandler h)
Method used for adding a
DeserializationProblemHandler for this
builder, at the head of the list (meaning it has priority over handler
registered earlier). |
B |
addMixIn(Class<?> target,
Class<?> mixinSource)
Method to use for defining mix-in annotations to use for augmenting
annotations that classes have, for purpose of configuration serialization
and/or deserialization processing.

public static List<Module> findModules()
ServiceLoader
facility, along with module-provided SPI.
Note that method does not do any caching, so calls should be considered potentially expensive.
public static List<Module> findModules(ClassLoader classLoader)
ServiceLoader
facility, along with module-provided SPI.
Note that method does not do any caching, so calls should be considered potentially expensive.
public B findAndAddModules()
addModules(builder.findModules());
As with findModules()
, no caching is done for modules, so care
needs to be taken to either create and share a single mapper instance;
or to cache introspected set of modules.
public B annotationIntrospector(AnnotationIntrospector intr)
AnnotationIntrospector
used by the
mapper instance to be built.
Note that doing this will replace the current introspector, which
may lead to unavailability of core Jackson annotations.
If you want to combine handling of multiple introspectors,
have a look at AnnotationIntrospectorPair

this method is more convenient. For example, some frameworks only allow configuring
of ObjectMapper instances and not ObjectWriter

public B addMixIn(Class<?> target, Class<?> mixinSource)
Note that standard mixin handler implementations will only allow a single mix-in
source class per target, so if there was a previous mix-in defined target it will
be cleared. This also means that you can remove mix-in definition by specifying
mixinSource
of null
public B registerSubtypes(Collection<Class<?>> subtypes)
public B polymorphicTypeValidator(PolymorphicTypeValidator ptv)
PolymorphicTypeValidator
to use for validating
subtypes when using Class name - based polymorphic deserialization
using annotations (validator used with "Default Typing" is specified by
passing in activateDefaultTyping(PolymorphicTypeValidator)
instead).
Validator will be called on validating types for which no default databind deserializer, or module-provided deserializer is found: typically this includes "POJO" (aka Bean) types, but not (for example) most container types.
public B activateDefaultTyping(PolymorphicTypeValidator subtypeValidator)
activateDefaultTyping(subtypeValidator, DefaultTyping.OBJECT_AND_NON_CONCRETE);
NOTE: choice of PolymorphicTypeValidator
to pass is critical for security
as allowing all subtypes can be risky for untrusted content.
public B activateDefaultTyping(PolymorphicTypeValidator subtypeValidator, ObjectMapper.DefaultTyping dti)
activateDefaultTyping(subtypeValidator, dti, JsonTypeInfo.As.WRAPPER_ARRAY);
NOTE: choice of PolymorphicTypeValidator
