JavaFX：将 SimpleLongProperty 绑定到标签并将 long 值格式化为人类可读的文件大小

我有一个绑定到两个属性的标签.第一个值(DeletedFileCountProperty)是一个简单的int，无需格式化.但是，如何将第二个属性(SimpleLongProperty)格式化为人类可读的filesize值？

例子:

我可以调用绑定中的humanReadableByteCount函数来设置值的格式吗？

迄今为止我的代码:

public class MainController implements Initializable {
    private final SimpleIntegerProperty deletedFilesCount = new SimpleIntegerProperty();
    private final SimpleLongProperty deletedFilesSize = new SimpleLongProperty();

    @FXML
    Label deletedFilesLabel;


    @Override
    public void initialize(URL url, ResourceBundle resourceBundle) {
        deletedFilesLabel.textProperty().bind(Bindings.format("Deleted files: %d (%d)", deletedFilesCountProperty(), deletedFilesSizeProperty()));
    }

    /**
    * formats a long number to a human readable file size value
    * returns something like: 2MB or 4GB and so on instead of very long Long values.
    */
    public static String humanReadableByteCount(long bytes, boolean si) {
        int unit = si ? 1000 : 1024;
        if (bytes < unit)
            return bytes + " B";
        int exp = (int) (Math.log(bytes) / Math.log(unit));
        String pre = (si ? "kMGTPE" : "KMGTPE").charAt(exp - 1) + (si ? "" : "i");
        return String.format("%.1f %sB", bytes / Math.pow(unit, exp), pre);
    }
}

谢谢
