maySerializeAsObject
public boolean maySerializeAsObject()
Convenience method, equivalent to calling:readerInstance.generator.maySerializeAsObject();
and used to determine whether Object Ids handled by the underlying generator may be in form of (JSON) Objects. Used for optimizing handling in cases where method returns false.- Since:
