JavaFX Label扩展无法强制

Question

public class UpdateLabel extends Label{
    private StringProperty updateKeyPrefix = new SimpleStringProperty();
    public String getUpdateKeyPrefix(){
        return this.updateKeyPrefix.get();
    }
    public void setUpdateKeyPrefix(String updateKeyPrefix){
        this.updateKeyPrefix.set(updateKeyPrefix);
    }

    private ObjectProperty<Enum<?>> updateKeyEnum = new SimpleObjectProperty<>();
    public Enum<?> getUpdateKeyEnum(){
        return this.updateKeyEnum.get();
    }
    public void setUpdateKeyEnum(Enum<?> updateKeyEnum){
        this.updateKeyEnum.set(updateKeyEnum);
    }

    public Update getUpdate(){
        return new Update(this.getUpdateKeyEnum(), this.getUpdateKeyPrefix(), null);
    }
}
