本文整理了Java中org.dspace.content.Bundle类的一些代码示例，展示了Bundle类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Bundle类的具体详情如下：
包路径：org.dspace.content.Bundle
类名称：Bundle

Bundle介绍

[英]Class representing bundles of bitstreams stored in the DSpace system

The corresponding Bitstream objects are loaded into memory. At present, there is no metadata associated with bundles - they are simple containers. Thus, the update method doesn't do much yet. Creating, adding or removing bitstreams has instant effect in the database.
[中]类，表示存储在DSpace系统中的比特流束
相应的位流对象被加载到内存中。目前，没有与捆绑包关联的元数据-它们是简单的容器。因此，update方法还没有做很多工作。创建、添加或删除位流在数据库中具有即时效果。

代码示例

static int countBitstream(BundleName bundleName, Item item) {

  for (Bundle bundle : item.getBundles()) {

      continue;
    }
    count += bundle.getBitstreams().size();
  }
  return count;
