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

Overrides:

findValueInstantiator in class ValueInstantiators.Base

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.
