Store Map values as Long instead of Int

Is there an existing issue?

• I have searched existing issues

Use case

I am storing a mapping:

val mapping = mutableMapOf(
    "key1" to mutableMapOf(
        "subkey1" to 1L,
        "subkey2" to 1L,
        "subkey3" to 1L
    ),
   "key2" to 1L

that is represented in the data class as follows:

@Entity
data class MyDataClass(
    @Id var id: Long = 0,
    var mapping: MutableMap<String, Any>? = null

ObjectBox will store the Long values as Ints due to not being wide enough. These breaks use cases where we do want to store the Long values as Long and not as Ints (for example test cases that use the same generated mock data to store in the database and to test against).

Proposed solution

Have an annotation that tells ObjectBox to store Long values as Long.

Alternatives

Tried using a PropertyConverter however this breaks for the mapping I've provided.

Additional context

Kotlin

L’issue ne nomme aucun fichier ni test. Commencez par suivre la manière dont les valeurs de MutableMap<String, Any> sont sérialisées et pourquoi le PropertyConverter tenté ne fonctionne pas pour ce mapping ; définissez ensuite comment l’annotation proposée doit préserver les valeurs Long et vérifiez que les valeurs stockées et récupérées restent des Long.
