    import com.haulmont.chile.core.annotations.MetaProperty;
    import com.haulmont.cuba.core.entity.AbstractNotPersistentEntity;
    
    @MetaClass(name = "sampler$CountryGrowth")
    public class CountryGrowth extends AbstractNotPersistentEntity {
    
        @MetaProperty
        protected String country;
    
        @MetaProperty
        protected Double year2014;
    
        @MetaProperty
        protected Double year2015;
    
        public void setCountry(String country) {
            this.country = country;
        }
    
        public String getCountry() {
            return country;
        }
    
        public void setYear2014(Double year2014) {
            this.year2014 = year2014;
        }
    
        public Double getYear2014() {
            return year2014;
        }
    
        public void setYear2015(Double year2015) {
            this.year2015 = year2015;
        }
    
        public Double getYear2015() {
