本文整理了Java中com.googlecode.objectify.Objectify.save()方法的一些代码示例，展示了Objectify.save()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。Objectify.save()方法的具体详情如下：
包路径：com.googlecode.objectify.Objectify
类名称：Objectify
方法名：save

Objectify.save介绍

[英]Start a save command chain. Allows you to save (or re-save) entity objects. Note that all command chain objects are immutable.

Saves do NOT cascade; if you wish to save an object graph, you must save each individual entity.

A quick example: ofy().save().entities(e1, e2, e3).now();

All command objects are immutable; this method returns a new object rather than modifying the current command object.
[中]启动保存命令链。允许您保存（或重新保存）实体对象。请注意，所有命令链对象都是不可变的。
储蓄不会层叠；如果要保存对象图，必须保存每个实体。
一个简单的例子：ofy（）。save（）。实体（e1、e2、e3）。现在（）；
所有命令对象都是不可变的；此方法返回一个新对象，而不是修改当前命令对象。

代码示例

代码示例来源：origin: objectify/objectify

public void flush() {
  final List<Result<?>> futures = new ArrayList<>();
  // Need to do this in a loop because @OnSave methods can enlist more deferred operations. Execution
  // of save or delete will undefer() all the relevant items, so both lists empty mean we're done.
  while (!operations.isEmpty() || !autogeneratedIdSaves.isEmpty()) {
    // Sort into two batch operations: one for save, one for delete.
    final List<Object> saves = new ArrayList<>();
    final List<Key<?>> deletes = new ArrayList<>();
    for (final Map.Entry<Key<?>, Object> entry : operations.entrySet()) {
      if (entry.getValue() == null)
        deletes.add(entry.getKey());
      else
        saves.add(entry.getValue());
    }
    saves.addAll(autogeneratedIdSaves);
    if (!saves.isEmpty())
      futures.add(ofy.save().entities(saves));
    if (!deletes.isEmpty())
      futures.add(ofy.delete().keys(deletes));
  }
  // Complete any pending operations
  for (final Result<?> future : futures) {
    future.now();
  }
}
