Class KotlinDefaultArgumentsFilter
java.lang.Object
org.jacoco.core.internal.analysis.filter.KotlinDefaultArgumentsFilter
- All Implemented Interfaces:
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.-
