public class AsDeductionTypeDeserializer extends AsPropertyTypeDeserializer
ATypeDeserializer
capable of deducing polymorphic types based on the fields available. Deduction is limited to the names of child properties (not their values or, consequently, any nested descendants). Exceptions will be thrown if not enough unique information is present to select a single subtype.The current deduction process does not support pojo-hierarchies such that the absence of child fields infers a parent type. That is, every deducible subtype MUST have some unique fields and the input data MUST contain said unique fields to provide a positive match.
