Item.save介绍

[英]Validates all pending changes currently recorded in this Session that apply to this Item or any of its descendants (that is, the subgraph rooted at this Item). If validation of all pending changes succeeds, then this change information is cleared from the Session. If the save occurs outside a transaction, the changes are persisted and thus made visible to other Sessions. If the save occurs within a transaction, the changes are not persisted until the transaction is committed.

If validation fails, then no pending changes are saved and they remain recorded on the Session. There is no best-effort or partial save.

The item in persistent storage to which a transient item is saved is
[中]验证当前在此Session中记录的、应用于此Item或其任何子体（即根于此项的子图）的所有挂起更改。如果所有挂起更改的验证成功，则此更改信息将从Session中清除。如果save发生在事务之外，则更改将被持久化，从而使其他Sessions可见。如果save发生在事务中，则在提交事务之前，不会保留更改。
如果验证失败，则不会保存任何挂起的更改，这些更改将保留在Session上。没有尽最大努力或部分节省。
永久存储器中保存临时项的项为
