There was a problem hiding this comment.
This is the top-level class that will be returned by get<type>Details() methods.
We use generics so that the customer's code doesn't have to unwrap an EppoValue if they retrieve the variation (which is top level, typed T).

🎟️ Ticket: FFESUPPORT-378 - Implement assignment details for common Java core
Motivation and Context
We want to bring detailed assignment capabilities (e.g.,
get<Type>Details()) to Android and Java SDKs.Description
This pull request gets the ball rolling by preparing the return type that the
get<Type>Details()methods will return.This is a generic
AssignmentDetails<T>, whereTwill beBoolean,Integer,Double,String, orJsonNode. The template type allows the top levelvariationof the details to be the desired type without the customer having to unbox.How has this been documented?
Documentation will be updated for the upstream SDKs once this is incorporated into them
How has this been tested?
This chunk is untested in this pull request as they are currently unused, but will be tested later on by changes to
FlagEvaluatorTest,BaseEppoClientTest, andBaseEppoClientBanditTest.
