Interface R2dbcEntityOperations
- All Superinterfaces:
FluentR2dbcOperations
,ReactiveDeleteOperation
,ReactiveInsertOperation
,ReactiveSelectOperation

- All Known Implementing Classes:
R2dbcEntityTemplate
Interface specifying a basic set of reactive R2DBC operations using entities. Implemented by
R2dbcEntityTemplate
. Not often used directly, but a useful option to enhance testability, as it can easily be
mocked or stubbed.- Since:
