Field Summary

Fields
Modifier and Type	Field and Description
`protected SettableAnyProperty`	`_anySetter` Fallback setter used for handling any properties that are not mapped to regular setters.
`protected HashMap<String,SettableBeanProperty>`	`_backRefProperties` Back-reference properties this bean contains (if any)
`protected BeanDescription`	`_beanDesc` Introspected information about POJO for deserializer to handle
`protected JsonPOJOBuilder.Value`	`_builderConfig` In addition, Builder may have additional configuration
`protected AnnotatedMethod`	`_buildMethod` When creating Builder-based deserializers, this indicates method to call on builder to finalize value.
`protected DeserializationConfig`	`_config`
`protected DeserializationContext`	`_context`
`protected HashSet<String>`	`_ignorableProps` Set of names of properties that are recognized but are to be ignored for deserialization purposes (meaning no exception is thrown, value is just skipped).
`protected boolean`	`_ignoreAllUnknown` Flag that can be set to ignore and skip unknown properties.
`protected HashSet<String>`	`_includableProps` Set of names of properties that are recognized and are set to be included for deserialization purposes (null deactivate this, empty includes nothing).
`protected List<ValueInjector>`	`_injectables` Value injectors for deserialization
`protected ObjectIdReader`	`_objectIdReader` Handler for Object Id values, if Object Ids are enabled for the bean type.
`protected Map<String,SettableBeanProperty>`	`_properties` Properties to deserialize collected so far.
`protected ValueInstantiator`	`_valueInstantiator` Object that will handle value instantiation for the bean type.

`protected void`	`_fixAccess(Collection<SettableBeanProperty> mainProps)`
`protected void`	`_handleBadAccess(IllegalArgumentException e0)` Helper method for linking root cause to "invalid type definition" exception; needed for troubleshooting issues with forcing access on later JDKs (as module definition boundaries are more strictly enforced).
`void`	`addBackReferenceProperty(String referenceName, SettableBeanProperty prop)` Method called to add a property that represents so-called back reference; reference that "points back" to object that has forward reference to currently built bean.
`void`	`addCreatorProperty(SettableBeanProperty prop)` Method called by deserializer factory, when a "creator property" (something that is passed via constructor- or factory method argument; instead of setter or field).

`void`	`addProperty(SettableBeanProperty prop)` Method to add a property setter.
`JsonDeserializer<?>`	`build()` Method for constructing a `BeanDeserializer`, given all information collected.

`JsonDeserializer<?>`	`buildBuilderBased(JavaType valueType, String expBuildMethodName)` Method for constructing a specialized deserializer that uses additional external Builder object during data binding.
`protected JsonDeserializer<?>`	`createBuilderBasedDeserializer(JavaType valueType, BeanPropertyMap propertyMap, boolean anyViews)` Extension point for overriding the actual creation of the builder deserializer.

    Method to add a property setter. Will ensure that there is no unexpected override; if one is found will throw a IllegalArgumentException.

```
    Method called by deserializer factory, when a "creator property" (something that is passed via constructor- or factory method argument; instead of setter or field).
    Default implementation does not do anything; we may need to revisit this decision if these properties need to be available through accessors. For now, however, we just have to ensure that we don't try to resolve types that masked setter/field has (see [JACKSON-700] for details).
