Most of the time, this can be left unimplemented and the framework will instantiate the instance itself. This is typically used when the object being deserialized is immutable, hence it has to be created with its state already set.
If this is overridden, the hasCustomInstantiateInstance()
method
must return true
in order for the framework to know to call
it.
