KotlinDefaultArgumentsFilter

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

All Implemented Interfaces:

IFilter
```
public final class KotlinDefaultArgumentsFilter
extends java.lang.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". And its value can't be zero - invocation with all arguments uses original non synthetic method, thus IFEQ instructions should be ignored.

    Description copied from interface: IFilter
    
    This method is called for every method. The filter implementation is expected to inspect the provided method and report its result to the given IFilterOutput instance.
    
    Specified by:
    
    filter in interface IFilter
    
    Parameters:
    
    methodNode - method to inspect
    
    context - context information for the method
    
    output - callback to report filtering results to
