Package org.neo4j.ogm.types.adapter

Class TemporalAmountAdapter

java.lang.Object
org.neo4j.ogm.types.adapter.TemporalAmountAdapter
All Implemented Interfaces:
Function<TemporalAmount,TemporalAmount>
public class TemporalAmountAdapter extends Object implements Function<TemporalAmount,TemporalAmount>
This adapter maps a Driver or embedded based TemporalAmount to a valid Java temporal amount. It tries to be as specific as possible: If the amount can be reliable mapped to a Period, it returns a period. If only fields are present that are no estimated time unites, than it returns a Duration.

In cases a user has used Cypher and its duration() function, i.e. like so CREATE (s:SomeTime {isoPeriod: duration('P13Y370M45DT25H120M')}) RETURN s a duration object has been created that cannot be represented by either a Period or Duration. The user has to map it to a plain TemporalAmount in this cases.
The Java Driver uses a org.neo4j.driver.v1.types.IsoDuration, embedded uses org.neo4j.values.storable.DurationValue for representing a temporal amount, but in the end, they can be treated the same. However be aware that the temporal amount returned in that case may not be equal to the other one, only represents the same amount after normalization.
