本文整理了Java中javax.jcr.Item.isNew()方法的一些代码示例，展示了Item.isNew()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。Item.isNew()方法的具体详情如下：
包路径：javax.jcr.Item
类名称：Item
方法名：isNew

Item.isNew介绍

[英]Returns true if this is a new item, meaning that it exists only in transient storage on the Session and has not yet been saved. Within a transaction, isNew on an Item may return false (because the item has been saved) even if that Item is not in persistent storage (because the transaction has not yet been committed).

Note that if an item returns true on isNew, then by definition is parent will return true on isModified.

Note that in read-only implementations, this method will always return false.
[中]如果这是一个新项目，则返回true，这意味着它仅存在于Session上的临时存储中，尚未保存。在事务中，Item上的isNew可能返回false（因为项目已保存），即使Item未在持久存储中（因为事务尚未提交）。
请注意，如果项目在isNew上返回true，则根据定义，父项将在isModified上返回true。
请注意，在只读实现中，此方法将始终返回false。
