## Class DeserializationConfig

- java.lang.Object
- - org.codehaus.jackson.map.MapperConfig<T>
  - - 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 by `ObjectMapper`, which makes a copy that is passed during serialization process to `DeserializerProvider` and `DeserializerFactory`.

  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")

      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.

      Specified by:

      Accessor for determining whether it is ok to try to force override of access modifiers to be able to get or set values of non-public Methods, Fields; to invoke non-public Constructors, Methods; or to instantiate non-public Classes. By default this is enabled, but on some platforms it needs to be prevented since if this would violate security constraints and cause failures.
      Specified by:
        `canOverrideAccessModifiers` in class `MapperConfig<DeserializationConfig>`
      Returns:
        True if access modifier overriding is allowed (and may be done for any Field, Method, Constructor or Class); false to prevent any attempts to override.

    - #### enable

          @Deprecated

      Deprecated. Since 1.9, it is preferable to use `without(org.codehaus.jackson.map.DeserializationConfig.Feature...)` and `with(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)
