本文整理了Java中io.helidon.config.Config.detach()方法的一些代码示例，展示了Config.detach()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。Config.detach()方法的具体详情如下：
包路径：io.helidon.config.Config
类名称：Config
方法名：detach

Config.detach介绍

[英]Returns a copy of the Config node with no parent.

The returned node acts as a root node for the subtree below it. Its key is the empty string; "". The original config node is unchanged, and the original and the copy point to the same children.

Consider the following configuration:

app: 
name: Example 1 
page-size: 20 
logging: 
app.level = INFO 
level = WARNING

The Config instances name1 and name2 represents same data and in fact refer to the same object:

Config name1 = config 
.get("app") 
.get("name"); 
Config name2 = config 
.get("app") 
.detach()               //DETACHED node 
.get("name"); 
assert name1.asString() == "Example 1"; 
assert name2.asString() == "Example 1";  //DETACHED node

The only difference is the key each node returns:

assert name1.key() == "app.name"; 
assert name2.key() == "name";            //DETACHED node

See #asMap() for example of config detaching.
[中]返回没有父节点的配置节点的副本。
返回的节点充当其下子树的根节点。它的键是空字符串；"". 原始配置节点不变，并且原始和副本指向相同的子节点。
考虑以下配置：

app: 
name: Example 1 
page-size: 20 
logging: 
app.level = INFO 
level = WARNING

配置实例name1和name2表示相同的数据，实际上引用相同的对象：

Config name1 = config 
.get("app") 
.get("name"); 
Config name2 = config 
.get("app") 
.detach()               //DETACHED node 
.get("name"); 
assert name1.asString() == "Example 1"; 
assert name2.asString() == "Example 1";  //DETACHED node

唯一的区别是每个节点返回的键：

assert name1.key() == "app.name"; 
assert name2.key() == "name";            //DETACHED node

有关配置分离的示例，请参见#asMap（）。
