public class Target extends EmployeeMapper {

 

    @Override

    public Target transformSource(Source employee) {

        if ( employee == null ) {

            return null;

        }

 

        Target.Builder target = Target.newBuilder();

        target.gender( toGender( employee.getGender() ) );

 

        return target.build();

    }

}

I want to keep a null and empty check on string to avoid mapping source gender to target gender

How to fix this ? Please help

I am expecting to be able generate Implementation class code with isStringNotNullOrEmpty if check before toGender() but only toGender is getting applied for mapping employee gender.
