本文整理了Java中org.jboss.cache.Node类的一些代码示例，展示了Node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。Node类的具体详情如下：
包路径：org.jboss.cache.Node
类名称：Node

Node介绍

[英]A Node is a Fqn logical grouping of data in the JBoss Cache. A node should be used to contain data for a single data record, for example information about a particular person or account.

One purpose of grouping cache data into separate nodes is to minimize transaction locking interference, and increase concurrency. So for example, when multiple threads or possibly distributed caches are acccessing different accounts simultaneously.

Another is that when making changes to this node, its data might be kept in a single database row or file on disk. (Persisted via the use of a org.jboss.cache.loader.CacheLoader.)

A node has references to its children, parent (each node except the root - defined by Fqn#ROOT - has a single parent) and data contained within the node (as key/value pairs). The data access methods are similar to the collections Map interface, but some are read-only or return copies of the underlying the data.
[中]节点是JBoss缓存中数据的Fqn逻辑分组。节点应用于包含单个数据记录的数据，例如关于特定人员或帐户的信息。
将缓存数据分组到单独节点的一个目的是最小化事务锁定干扰，并提高并发性。例如，当多个线程或可能分布的缓存同时访问不同的帐户时。
另一个原因是，在对该节点进行更改时，其数据可能保存在单个数据库行或磁盘上的文件中。（通过使用org.jboss.cache.loader.CacheLoader保存。）
一个节点引用了它的子节点、父节点（除根节点（由Fqn#root定义）外的每个节点都有一个父节点）和节点中包含的数据（作为键/值对）。数据访问方法与collections Map接口类似，但有些是只读的，或者返回基础数据的副本。
