java - TreeViewer 选择和剪贴板

Question

是否可以将多个对象(表示 TreeViewer 选择)放入剪贴板？这是我的 Cut 代码。

static public void Cut(EssentialData dataInst)
{
    IStructuredSelection selection = (IStructuredSelection)dataInst.getTreeViewer().getSelection();

    if(selection == null)
    {
        System.err.println("selection received was null");
        return;
    }

    Object[] objects = selection.toArray();

    //because setContents requires a Transfer object for every object sent
    List<Transfer> typesList = new ArrayList<>();

    for(int i = 0; i < objects.length; i++)
        typesList.add(FileEntryTransfer.getInstance());

    final Clipboard cb = new Clipboard(Display.getCurrent());
    cb.setContents(objects, typesList.toArray(new Transfer[]{}));
    cb.dispose();

    for(int i = 0; i < objects.length; i++)
        dataInst.getFileManager().removeEntry((FileEntry)objects[i]);

    dataInst.getTreeViewer().refresh(false);
}

我想做的是将多项选择(FileEntry 的实例)放入剪贴板。

FileEntryTransfer 是我自定义的 ByteArrayTransfer 类，我也将其用于免打扰。它运行良好，但我注意到 setContents() 实际上只向它发送一个 FileEntry 对象，而不是一组对象(这正是我想要的)。

有什么想法吗？

[edit]感谢 vanaprogeja，我解决了它

cb.setContents(new Object[]{ objects }, new Transfer[] { FileEntryTransfer.getInstance() });

怎么样:

cb.setContents(new Object[]{ objects },
    new Transfer[] { FileEntryTransfer.getInstance() });
