Class EnumEmptyConstructorFilter

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

All Implemented Interfaces:

IFilter

public final class EnumEmptyConstructorFilter
extends Object
implements IFilter

Filters empty enum constructors. Constructor of enum is invoked from static initialization block to create instance of each enum constant. So it won't be executed if number of enum constants is zero. Such enums are sometimes used as alternative to classes with static utilities and private empty constructor. Implicit constructor of enum created by compiler doesn't have a synthetic flag and refers to a line of enum definition. Therefore in order to not have partial coverage of enum definition line in enums without enum constants and similarly to filter of private empty constructors - empty constructor in enums without additional parameters should be filtered out even if it is not implicit.
