DeserializationContext (The Adobe AEM Quickstart and Web Application.)

java.lang.Object
- com.fasterxml.jackson.databind.DatabindContext
- - com.fasterxml.jackson.databind.DeserializationContext

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

DefaultDeserializationContext
```
public abstract class DeserializationContext
extends DatabindContext
implements java.io.Serializable
```
Context for the process of deserialization a single root-level value. Used to allow passing in configuration settings and reusable temporary objects (scrap arrays, containers).
Instance life-cycle is such that a partially configured "blueprint" object is registered with ObjectMapper (and ObjectReader, and when actual instance is needed for deserialization, a fully configured instance will be created using a method in extended internal API of sub-class (DefaultDeserializationContext.createInstance(com.fasterxml.jackson.databind.DeserializationConfig, com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.InjectableValues)). Each instance is guaranteed to only be used from single-threaded context; instances may be reused if (and only if) no configuration has changed.
Defined as abstract class so that implementations must define methods for reconfiguring blueprints and creating instances.

    Method that deserializers should call if they fail to instantiate value due to lack of viable instantiator (usually creator, that is, constructor or static factory method). Method should be called at point where value has not been decoded, so that handler has a chance to handle decoding using alternate mechanism, and handle underlying content (possibly by just skipping it) to keep input state valid
    
    Parameters:
    
    instClass - Type that was to be instantiated
    
    valueInst - (optional) Value instantiator to be used, if any; null if type does not use one for instantiation (custom deserialiers don't; standard POJO deserializer does)

```
    Method that deserializers should call if they encounter a type id (for polymorphic deserialization) that cannot be resolved to an actual type; usually since there is no mapping defined. Default implementation will try to call DeserializationProblemHandler.handleUnknownTypeId(com.fasterxml.jackson.databind.DeserializationContext, com.fasterxml.jackson.databind.JavaType, java.lang.String, com.fasterxml.jackson.databind.jsontype.TypeIdResolver, java.lang.String) on configured handlers, if any, to allow for recovery; if recovery does not succeed, will throw exception constructed with invalidTypeIdException(com.fasterxml.jackson.databind.JavaType, java.lang.String, java.lang.String).
    
    Parameters:
    
    baseType - Base type from which resolution starts
    
    id - Type id that could not be converted
    
    extraDesc - Additional problem description to add to default exception message, if resolution fails.
    
    Returns:
    
    JavaType that id resolves to
    
    Throws:
    
    java.io.IOException - To indicate unrecoverable problem, if resolution cannot be made to work
