open fun <Owner : PsiElement, Type> IdeMetaPlugin.addParameterInfoHandler(handler: ParameterInfoHandler<Owner, Type>): ExtensionPhase

registers a ParameterInfoHandler The latter is generally used to render properties and types of parameters for code insight.

//Source not found: KotlinLambdaParameterInfoHandler

registers a ParameterInfoHandlerWithTabActionSupport. One among other goal’s in this extension, is to facilitate a Mapping between Owner -> ActualType, or in other words from List<ActualType> -> ActualType. This is evident in actualParameters. Check out addParameterInfoHandlerForKotlin for a minimal example to what this extension may abstract to. The difference between addParameterInfoHandlerForKotlin and this function is that the latter is language independent.


ActualType - is one parameter of the collection in Owner

Type - being an Descriptor
