Class DeserializationConfig

- org.codehaus.jackson.map.DeserializationConfig

- All Implemented Interfaces:
ClassIntrospector.MixInResolver
public class DeserializationConfig extends MapperConfig<T>
Object that contains baseline configuration for deserialization process. An instance is owned byObjectMapper, which makes a copy that is passed during serialization process toDeserializerProviderandDeserializerFactory.Note: although configuration settings can be changed at any time (for factories and instances), they are not guaranteed to have effect if called after constructing relevant mapper or deserializer instance. This because some objects may be configured, constructed and cached first time they are needed.
As of version 1.9, the goal is to make this class eventually immutable. Because of this, existing methods that allow changing state of this instance are deprecated in favor of methods that create new instances with different configuration ("fluent factories")

fromAnnotations
@Deprecated public void fromAnnotations(java.lang.Class<?> cls)
Deprecated.Since 1.9, it is preferably to explicitly configure instances; this method also modifies existing instance which is against immutable design goals of this class.Method that checks class annotations that the argument Object has, and modifies settings of this configuration object accordingly, similar to how those annotations would affect actual value classes annotated with them, but with global scope. Note that not all annotations have global significance, and thus only subset of Jackson annotations will have any effect.Ones that are known to have effect are:
- Specified by:
fromAnnotationsin classMapperConfig<DeserializationConfig>- Parameters:
cls- Class of which class annotations to use for changing configuration settings
-
createUnshared
public DeserializationConfig createUnshared(SubtypeResolver subtypeResolver)

-
enable
@Deprecated public void enable(DeserializationConfig.Feature f)
Deprecated.Since 1.9, it is preferable to usewith(org.codehaus.jackson.map.DeserializationConfig.Feature...)instead; this method is deprecated as it modifies current instance instead of creating a new one (as the goal is to make this class immutable)Method for enabling specified feature.
