only implicite mapper method called apply are supported in dedicated class with at least one @MapperFactory

[lesaint]

An IllegalArgumentException is raised by DAMapping when processing a dedicate class with a method/constructor annotated with @MapperFactory and a mapper method which is not called apply.

sample

Processing of the following MapperFactory dedicated class:

import fr.javatronic.damapping.annotation.Mapper;
import fr.javatronic.damapping.annotation.MapperFactory;

@Mapper
public class MostSimpleFactory {
  @MapperFactory
  public MostSimpleFactory(boolean a) {
    // implementation does not matter
  }

  public String apply(Integer input) {
    return null; // implementation does not matter
  }
}

Fails with the following stacktrace:
