    - #### DEFAULT_KEY_DESERIALIZERS

          protected static final KeyDeserializers[] DEFAULT_KEY_DESERIALIZERS

      By default we plug default key deserializers using as "just another" set of of key deserializers.
      Since:
        2.2

    - #### _additionalDeserializers

          protected final Deserializers[] _additionalDeserializers

      List of providers for additional deserializers, checked before considering default basic or bean deserializers.

    - #### _additionalKeyDeserializers

          protected final KeyDeserializers[] _additionalKeyDeserializers

      List of providers for additional key deserializers, checked before considering standard key deserializers.

    - #### _modifiers

          protected final BeanDeserializerModifier[] _modifiers

      List of modifiers that can change the way `BeanDeserializer` instances are configured and constructed.

    - #### _abstractTypeResolvers

          protected final AbstractTypeResolver[] _abstractTypeResolvers

      List of objects that may be able to resolve abstract types to concrete types. Used by functionality like "mr Bean" to materialize types as needed.

  - ### Method Detail

    - #### withAdditionalDeserializers

          public DeserializerFactoryConfig withAdditionalDeserializers(Deserializers additional)

      Fluent/factory method used to construct a configuration object that has same deserializer providers as this instance, plus one specified as argument. Additional provider will be added before existing ones, meaning it has priority over existing definitions.

    - #### withAdditionalKeyDeserializers

          public DeserializerFactoryConfig withAdditionalKeyDeserializers(KeyDeserializers additional)

      Fluent/factory method used to construct a configuration object that has same key deserializer providers as this instance, plus one specified as argument. Additional provider will be added before existing ones, meaning it has priority over existing definitions.

    - #### withDeserializerModifier

          public DeserializerFactoryConfig withDeserializerModifier(BeanDeserializerModifier modifier)

      Fluent/factory method used to construct a configuration object that has same configuration as this instance plus one additional deserialiazer modifier. Added modifier has the highest priority (that is, it gets called before any already registered modifier).

    - #### withAbstractTypeResolver

          public DeserializerFactoryConfig withAbstractTypeResolver(AbstractTypeResolver resolver)

      Fluent/factory method used to construct a configuration object that has same configuration as this instance plus one additional abstract type resolver. Added resolver has the highest priority (that is, it gets called before any already registered resolver).

    - #### withValueInstantiators

          public DeserializerFactoryConfig withValueInstantiators(ValueInstantiators instantiators)

      Fluent/factory method used to construct a configuration object that has same configuration as this instance plus specified additional value instantiator provider object. Added instantiator provider has the highest priority (that is, it gets called before any already registered resolver).
      Parameters:
        `instantiators` - Object that can provide `ValueInstantiator`s for constructing POJO values during deserialization
