Class ValueInstantiators.Base

java.lang.Object

com.fasterxml.jackson.databind.deser.ValueInstantiators.Base

All Implemented Interfaces:

ValueInstantiators

Direct Known Subclasses:

SimpleValueInstantiators

Enclosing interface:

ValueInstantiators

public static class ValueInstantiators.Base
extends Object
implements ValueInstantiators

Basic "NOP" implementation that can be used as the base class for custom implementations. Safer to extend (instead of implementing ValueInstantiators) in case later Jackson versions add new methods in base interface.

findValueInstantiator

public ValueInstantiator findValueInstantiator(DeserializationConfig config,
 BeanDescription beanDesc,
 ValueInstantiator defaultInstantiator)

Description copied from interface: ValueInstantiators

Method called to find the ValueInstantiator to use for creating instances of specified type during deserialization. Note that a default value instantiator is always created first and passed; if an implementation does not want to modify or replace it, it has to return passed instance as is (returning null is an error)

Specified by:

findValueInstantiator in interface ValueInstantiators

Parameters:

config - Deserialization configuration in use

beanDesc - Additional information about POJO type to be instantiated

defaultInstantiator - Instantiator that will be used if no changes are made; passed to allow custom instances to use annotation-provided information (note, however, that earlier ValueInstantiators may have changed it to a custom instantiator already)

Returns:

Instantiator to use; either defaultInstantiator that was passed, or a custom variant; cannot be null.
