Description
Minimal repro
package com.example
interface Interface {
val state: Int
}
abstract class Primitive : Interface
class Composite : Interface {
private val primitives = emptyList<Primitive>()
override val state: Int
get() =
42 + primitives.sumOf(Interface::state)
}
Even a smaller repro
package com.example
class Klazz {
private val children = emptyList<Klazz>()
val state: Int
get() =
42 + children.sumOf(Klazz::state)
}
Observed behavior
file.kt:13:9: [WRONG_NAME_OF_VARIABLE_INSIDE_ACCESSOR] use `field` keyword instead of property name inside property accessors: get() =... (diktat-ruleset:getter-setter-fields)
An additional problem with the above error is that the special field identifier is only allowed when there's a backing field (i. e. the property has been initialized), e. g.:
val state: Int = 42
get() {
println(field)
return 44
}
