BasicDeserializerFactory (Red Hat JBoss Enterprise Application Platform 7.1.0.Beta1 public API)

java.lang.Object
- com.fasterxml.jackson.databind.deser.DeserializerFactory
- - com.fasterxml.jackson.databind.deser.BasicDeserializerFactory

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BeanDeserializerFactory
```
public abstract class BasicDeserializerFactory
extends DeserializerFactory
implements Serializable
```
Abstract factory base class that can provide deserializers for standard JDK classes, including collection classes and simple heuristics for "upcasting" common collection interface types (such as Collection).
Since all simple deserializers are eagerly instantiated, and there is no additional introspection or customizability of these types, this factory is stateless.

```
Description copied from class: DeserializerFactory

Method called to find and create a type information deserializer for given base type, if one is needed. If not needed (no polymorphic handling configured for type), should return null.
Note that this method is usually only directly called for values of container (Collection, array, Map) types and root values, but not for bean property values.

Specified by:

findTypeDeserializer in class DeserializerFactory

baseType - Declared base type of the value to deserializer (actual deserializer type will be this type or its subtype)

Returns:

Type deserializer to use for given base type, if one is needed; null if not.

Throws:

JsonMappingException
