com.intellij.rt.coverage.instrumentation.filters.branches.KotlinWhenStringFilter

public class KotlinWhenStringFilter
extends CoverageFilter

In when by String construction, Kotlin compiler generates extra branches. Firstly, check for null string if applicable:

1. IFNULL (default branch)

Secondly, switch by hashCode:

1. INVOKEVIRTUAL java/lang/String.hashCode ()I
2. LOOKUPSWITCH

And then in each branch of the switch there is a check for equality:

1. LDC
2. INVOKEVIRTUAL java/lang/String.equals (Ljava/lang/Object;)Z
3. IFNE
4. [OPTIONAL for the last branch]GOTO (default label)
