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.

    Constructor used by ObjectMapper to create default configuration object instance.
- Method Detail
  - with
```
public DeserializationConfig with(SubtypeResolver str)
```
    Description copied from class: MapperConfigBase
    
    Method for constructing and returning a new instance with different SubtypeResolver to use.
    NOTE: make sure to register new instance with ObjectMapper if directly calling this method.
    
    Specified by:
    
    with in class MapperConfigBase<DeserializationFeature,DeserializationConfig>
  - withRootName
```
public DeserializationConfig withRootName(PropertyName rootName)
```
    Description copied from class: MapperConfigBase
    
    Method for constructing and returning a new instance with different root name to use (none, if null).
    Note that when a root name is set to a non-Empty String, this will automatically force use of root element wrapping with given name. If empty String passed, will disable root name wrapping; and if null used, will instead use SerializationFeature to determine if to use wrapping, and annotation (or default name) for actual root name to use.
    
    Specified by:
    
    withRootName in class MapperConfigBase<DeserializationFeature,DeserializationConfig>
    
    Parameters:
    
    rootName - to use: if null, means "use default" (clear setting); if empty String ("") means that no root name wrapping is used; otherwise defines root name to use.
