KPropertyPath doesn't support Iterables
The KPropertyPath currently doesn't support references from Iterables such as List, Set, etc. to the type of the element.
data class User(
val name: String,
val addresses: List<Address>
) {
data class Address(
val street: String
)
}
val path = User::addresses / User.Address::street // a type mismatch between the expected the `Address` and offered `List<Address>` occurs here
The implementation in org.springframework.data.mapping.KPropertyPath should be able to construct paths such as addresses.street for the usage in indexes, queries and aggregations to leverage the type-safety of Kotlin for paths references in Spring Data MongoDB.
A similar implementation is offered by the now deprecated project KMongo, see KPropertyPath.kt and Properties.kt.
