## Class DeserializationConfig

- java.lang.Object
- - com.fasterxml.jackson.databind.cfg.MapperConfig<T>
  - - com.fasterxml.jackson.databind.cfg.MapperConfigBase<DeserializationFeature,DeserializationConfig>
    - - com.fasterxml.jackson.databind.DeserializationConfig

- All Implemented Interfaces:
    ClassIntrospector.MixInResolver, java.io.Serializable

      public final class DeserializationConfig
      extends MapperConfigBase<DeserializationFeature,DeserializationConfig>
      implements java.io.Serializable

  Object that contains baseline configuration for deserialization process. An instance is owned by `ObjectMapper`, which passes an immutable instance to be used for deserialization process.

  Note that instances are considered immutable and as such no copies should need to be created for sharing; all copying is done with "fluent factory" methods.
