`protected Object`	`handlePolymorphic(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt, Object bean, TokenBuffer unknownTokens)` Method called in cases where we may have polymorphic deserialization case: that is, type of Creator-constructed bean is not the type of deserializer itself.

```
    Fluent factory for creating a variant that can handle POJO output as a JSON Array. Implementations may ignore this request if no such input is possible.
    
    Since:
    
    2.1
  - resolve
```
public void resolve(DeserializationContext ctxt)
             throws JsonMappingException
```
    Method called to finalize setup of this deserializer, after deserializer itself has been registered. This is needed to handle recursive and transitive dependencies.
    
    Specified by:
    
    resolve in interface ResolvableDeserializer
    
    Parameters:
    ctxt - Context to use for accessing configuration, resolving secondary deserializers
    
    Throws:
    
    JsonMappingException
  - findConvertingDeserializer
```
protected JsonDeserializer<Object> findConvertingDeserializer(DeserializationContext ctxt,

    Throws:
    
    JsonMappingException

  - createContextual
```
public JsonDeserializer<?> createContextual(DeserializationContext ctxt,

                                     throws JsonMappingException
```
    Although most of post-processing is done in resolve(), we only get access to referring property's annotations here; and this is needed to support per-property ObjectIds. We will also consider Shape transformations (read from Array) at this point, since it may come from either Class definition or property.
    
    Specified by:
    
    createContextual in interface ContextualDeserializer
    
    Parameters:
    ctxt - Deserialization context to access configuration, additional deserializers that may be needed by this deserializer
    property - Method, field or constructor parameter that represents the property (and is used to assign deserialized value). Should be available; but there may be cases where caller can not provide it and null is passed instead (in which case impls usually pass 'this' deserializer as is)
    
    Returns:
    Deserializer to use for deserializing values of specified property; may be this instance or a new instance.
    
    Throws:

```
    Helper method that will handle gruesome details of dealing with properties that have non-static inner class as value...
  - isCachable
```
public boolean isCachable()
```
    Description copied from class: JsonDeserializer
    
    Method called to see if deserializer instance is cachable and usable for other properties of same type (type for which instance was created).
    Note that cached instances are still resolved on per-property basis, if instance implements ResolvableDeserializer: cached instance is just as the base. This means that in most cases it is safe to cache instances; however, it only makes sense to cache instances if instantiation is expensive, or if instances are heavy-weight.
    Default implementation returns false, to indicate that no caching is done.
    
    Overrides:
    
    isCachable in class JsonDeserializer<Object>
  - handledType
```
public Class<?> handledType()
```
    Description copied from class: JsonDeserializer
    
    Method for accessing type of values this deserializer produces. Note that this information is not guaranteed to be exact -- it may be a more generic (super-type) -- but it should not be incorrect (return a non-related type).
    Default implementation will return null, which means almost same same as returning Object.class would; that is, that nothing is known about handled type.
    
    Overrides:
    
    handledType in class StdDeserializer<Object>
  - getObjectIdReader
```
public ObjectIdReader getObjectIdReader()
```
    Overridden to return true for those instances that are handling value for which Object Identity handling is enabled (either via value type or referring property).
    
    Overrides:
    
    getObjectIdReader in class JsonDeserializer<Object>
    
    Returns:
    ObjectIdReader used for resolving possible Object Identifier value, instead of full value serialization, if deserializer can do that; null if no Object Id is expected.

  - getKnownPropertyNames
```
public Collection<Object> getKnownPropertyNames()
```
    Description copied from class: JsonDeserializer
    
    Method that will either return null to indicate that type being deserializers has no concept of properties; or a collection of identifiers for which toString will give external property name. This is only to be used for error reporting and diagnostics purposes (most commonly, to accompany "unknown property" exception).
    
    Overrides:

  - findProperty
```
public SettableBeanProperty findProperty(int propertyIndex)
```
    Alternate find method that tries to locate a property with given property index. Note that access by index is not necessarily faster than by name, since properties are not directly indexable; however, for most instances difference is not significant as number of properties is low.

```
    Helper method we need to do necessary conversion from whatever native object id type is, into declared type that Jackson internals expect. This may be simple cast (for String ids), or something more complicated; in latter case we may need to create bogus content buffer to allow use of id deserializer.

```
    Alternative deserialization method used when we expect to see Object Id; if so, we will need to ensure that the Id is seen before anything else, to ensure that it is available for solving references, even if JSON itself is not ordered that way. This may require buffering in some cases, but usually just a simple lookup to ensure that ordering is correct.

    beanOrClass - Instance that is being populated by this deserializer, or if not known, Class that would be instantiated. If null, will assume type is what StdDeserializer.getValueClass() returns.

    Method called in cases where we may have polymorphic deserialization case: that is, type of Creator-constructed bean is not the type of deserializer itself. It should be a sub-class or implementation class; either way, we may have more specific deserializer to use for handling it.
    
    Parameters:

```
    Method that will modify caught exception (passed in as argument) as necessary to include reference information, and to ensure it is a subtype of IOException, or an unchecked exception.
    Rules for wrapping and unwrapping are bit complicated; essentially:
    - Errors are to be passed as is (if uncovered via unwrapping)
    - "Plain" IOExceptions (ones that are not of type JsonMappingException are to be passed as is
