🎟️ 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
The generic
AssignmentDetailsreturned includes the (template typed) variation value. To spare upstream callers from having to unbox/cast, we add a new method for EppoValues that unwrap to Boolean, Integer, Double, String, and JsonNode. We will do this before returning the details.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 is tested in
EppoValueTest.
