如何积极参与 EPartService？

Question

我想通过使用 EPartService 来积极参与。我可以为此使用 EPartService 吗？

Answer 1

如果你想在诸如命令处理程序之类的东西中获得活动部分，你可以将其作为参数注入：

@Execute
public void execute(@Named(IServiceConstants.ACTIVE_PART) MPart activePart)
{
  ... handler code
}

如果您想要所有当前显示的部件的列表，您可以使用 EPartService。类似于：

@Inject
MApplication app;

@Inject
EPartService partService;

// Find all the `MPart` objects in the current presentation

Collection<MPart> parts = partService.getParts();

// Filter the list to include just the parts that are current being displayed (rendered)

parts = parts.stream().filter(MPart::isToBeRendered).collect(Collectors.toList());

注意：此代码需要Java 8
