Redundant qualifier name

Reports redundant qualifiers (or their parts) on class names, functions, and properties.

A fully qualified name is an unambiguous identifier that specifies which object, function, or property a call refers to. In the contexts where the name can be shortened, the inspection informs on the opportunity and the associated 'Remove redundant qualifier name' quick-fix allows amending the code.

Examples:

package my.simple.name
import kotlin.Int.Companion.MAX_VALUE

class Foo

fun main() {
    val a = my.simple.name.Foo()    // 'Foo' resides in the declared 'my.simple.name' package, qualifier is redundant
    val b = kotlin.Int.MAX_VALUE    // Can be replaced with 'MAX_VALUE' since it's imported
    val c = kotlin.Double.MAX_VALUE // Can be replaced with 'Double.MAX_VALUE' since built-in types are imported automatically
}

After the quick-fix is applied:

package my.simple.name
import kotlin.Int.Companion.MAX_VALUE

class Foo

fun main() {
    val a = Foo()
    val b = MAX_VALUE
    val c = Double.MAX_VALUE
}
