Hi!

One question, how can I check if a function is inside of interface or class?

I want to check if a method is anotated with @Deprecated but only need to check interfaces, not implementations

Current code on thread

[alorma]

class DeprecateBlockingMethods : Rule() {

  override val issue = Issue(
    javaClass.simpleName,
    Severity.Warning,
    "This rule reports a method with Blocking on the name without @Deprecated annotation",
    Debt(mins = 1)
  )

  override fun visitNamedFunction(function: KtNamedFunction) {
    super.visitNamedFunction(function)

    if (!function.isPublic) return
    if (!function.isBlocking) return

    if (!function.isAnnotatedWithDeprecated) {
      report(CodeSmell(issue,
        Entity.from(function.identifyingElement!!),
        message = "The blocking method ${function.name} is not annotated with @Deprecated"))
    }
  }

  private val KtNamedFunction.isBlocking
    get() = name?.contains("Blocking") == true

  private val KtNamedFunction.isAnnotatedWithDeprecated: Boolean
    get() {
      return modifierList?.annotationEntries?.any { annotation ->
        annotation.shortName?.asString() == "Deprecated"
      } == true
    }

I’d say you should try with

getNonStrictParentOfType<KtClass>() ?: return

The method above is also the implementation for UAST as well

Also KtClass covers both class and interface FYI

Thanks, it worked

getNonStrictParentOfType<KtClass>() ?: return
