Description copied from class: ValueInstantiator

Method called to create value instance from a JSON value when no data needs to passed to creator (constructor, factory method); typically this will call the default constructor of the value object. It will only be used if more specific creator methods are not applicable; hence "default".

This method is called if ValueInstantiator.getFromObjectArguments(com.fasterxml.jackson.databind.DeserializationConfig) returns null or empty List.

Specified by:

createUsingDefault in class JDKValueInstantiators.JDKValueInstantiator

Throws:

IOException
