'filterIsInstance' call with a class literal argument
Reports calls of the Kotlin standard library function filterIsInstance
with a class literal argument. It is more idiomatic to use a version of this function with a reified type parameter, to avoid the ::class.java
syntax.
Note: inspection is not reported for generic class literals because the Class<*, *>
syntax in the type argument list may be undesirable.
Example:
fun foo(list: List<*>) {
list.filterIsInstance(Int::class.java)
}
After the quick-fix is applied:
fun foo(list: List<*>) {
list.filterIsInstance<Int>()
}
