- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `protected JavaType` | `_baseType`
    `protected JavaType` | `_defaultImpl` Type to use as the default implementation, if type id is missing or can not be resolved.
    `protected JsonDeserializer<Object>` | `_defaultImplDeserializer`
    `protected HashMap<String,JsonDeserializer<Object>>` | `_deserializers` For efficient operation we will lazily build mappings from type ids to actual deserializers, once needed.
    `protected TypeIdResolver` | `_idResolver`
    `protected BeanProperty` | `_property`

  - ### Constructor Summary

    Constructors
    Modifier | Constructor and Description
    --- | ---
    `protected` | `TypeDeserializerBase(JavaType baseType, TypeIdResolver idRes, BeanProperty property)` Deprecated. Since 1.9, use the constructor that takes 'defaultImpl'
    `protected` | `TypeDeserializerBase(JavaType baseType, TypeIdResolver idRes, BeanProperty property, Class<?> defaultImpl)`

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected JsonDeserializer<Object>` | `_findDefaultImplDeserializer(DeserializationContext ctxt)`
    `protected JsonDeserializer<Object>` | `_findDeserializer(DeserializationContext ctxt, String typeId)`
    `String` | `baseTypeName()`
    `Class<?>` | `getDefaultImpl()` Accessor for "default implementation" type; optionally defined class to use in cases where type id is not accessible for some reason (either missing, or can not be resolved)
    `String` | `getPropertyName()` Name of property that contains type information, if property-based inclusion is used.
    `TypeIdResolver` | `getTypeIdResolver()` Accessor for object that handles conversions between types and matching type ids.
    `abstract JsonTypeInfo.As` | `getTypeInclusion()` Accessor for type information inclusion method that deserializer uses; indicates how type information is (expected to be) embedded in JSON input.
    `String` | `toString()`
