```
public abstract class SettableBeanProperty
extends ConcreteBeanPropertyBase
implements Serializable
```
Base class for deserializable properties of a bean: contains both type and name definitions, and reflection-based set functionality. Concrete sub-classes implement details, so that field- and setter-backed properties, as well as a few more esoteric variations, can be handled.

Modifier and Type	Class and Description
`static class`	`SettableBeanProperty.Delegating` Helper class that is designed to both make it easier to sub-class delegating subtypes and to reduce likelihood of breakage when new methods are added.

Field Summary

Fields
Modifier and Type	Field and Description
`protected Annotations`	`_contextAnnotations` Class that contains this property (either class that declares the property or one of its subclasses), class that is deserialized using deserializer that contains this property.
`protected String`	`_managedReferenceName` If property represents a managed (forward) reference, we will need the name of reference for later linking.
`protected NullValueProvider`	`_nullProvider` Entity used for possible translation from `null` into non-null value of type of this property.
`protected ObjectIdInfo`	`_objectIdInfo` This is the information for object identity associated with the property.
`protected int`	`_propertyIndex` Index of property (within all property of a bean); assigned when all properties have been collected.
`protected PropertyName`	`_propName` Logical name of the property (often but not always derived from the setter method name)
`protected JavaType`	`_type` Base type for property; may be a supertype of actual value.
`protected JsonDeserializer<Object>`	`_valueDeserializer` Deserializer used for handling property value.
`protected TypeDeserializer`	`_valueTypeDeserializer` If value will contain type information (to support polymorphic handling), this is the type deserializer used to handle type resolution.
`protected ViewMatcher`	`_viewMatcher` Helper object used for checking whether this property is to be included in the active view, if property is view-specific; null otherwise.
`protected PropertyName`	`_wrapperName`
`protected static JsonDeserializer<Object>`	`MISSING_VALUE_DESERIALIZER` To avoid nasty NPEs, let's use a placeholder for _valueDeserializer, if real deserializer is not (yet) available.

```
    Method called to deserialize appropriate value, given parser (and context), and set it using appropriate mechanism. Pre-condition is that passed parser must point to the first token that should be consumed to produce the value (the only value for scalars, multiple for Objects and Arrays).

    This method is needed by some specialized bean deserializers, and also called by some deserializeAndSet(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, java.lang.Object) implementations.
    Pre-condition is that passed parser must point to the first token that should be consumed to produce the value (the only value for scalars, multiple for Objects and Arrays).
    Note that this method is final for performance reasons: to override functionality you must override other methods that call this method; this method should also not be called directly unless you really know what you are doing (and probably not even then).
