Class KotlinDefaultArgumentsFilter

java.lang.Object
  org.jacoco.core.internal.analysis.filter.KotlinDefaultArgumentsFilter

All Implemented Interfaces:

IFilter

public final class KotlinDefaultArgumentsFilter
extends Object
implements IFilter

Filters branches that Kotlin compiler generates for default arguments. For each default argument Kotlin compiler generates following bytecode to determine if it should be used or not:

 ILOAD maskVar
 ICONST_x, BIPUSH, SIPUSH, LDC or LDC_W
 IAND
 IFEQ label
 default argument
 label:
 

Where maskVar is penultimate argument of synthetic method with suffix "$default" or of synthetic constructor with last argument "kotlin.jvm.internal.DefaultConstructorMarker". And its value can't be zero - invocation with all arguments uses original non synthetic method, thus IFEQ instructions should be ignored.
