Hi, how can I get a list of KMutableProperty1<*, *> for the members of my class ?
I only found memberProperties which returns a list of KProperty<*, *> and not castable so what should I use ?

[Roukanken]

a simple is KMutableProperty1<*, *> check on the list should do it
add a filterIsInstance which does the is check on whole collection and buala:

data class Example(
    val one: Int,
    var two: String,
    val three: String,
    var four: Int,
)

val mutableProperties: List<KMutableProperty1<*, *>> =
    Example::class.memberProperties.filterIsInstance<KMutableProperty1<*, *>>()

mutableProperties.map { it.name to it.returnType }  
// == [(four, <http://kotlin.Int|kotlin.Int>), (two, kotlin.String)]

(the type of the variable is not needed, only there to be clear what it is)
