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

JSONObject.wrap介绍

[英]Wraps the given object if necessary.

If the object is null or , returns #NULL. If the object is a JSONArray or JSONObject, no wrapping is necessary. If the object is NULL, no wrapping is necessary. If the object is an array or Collection, returns an equivalent JSONArray. If the object is a Map, returns an equivalent JSONObject. If the object is a primitive wrapper type or String, returns the object. Otherwise if the object is from a java package, returns the result of toString. If wrapping fails, returns null.
[中]如有必要，包装给定对象。
如果对象为null或，则返回#null。如果对象是JSONArray或JSONObject，则不需要包装。如果对象为空，则不需要换行。如果对象是数组或集合，则返回等效的JSONArray。如果对象是映射，则返回等效的JSONObject。如果对象是基本包装类型或字符串，则返回该对象。否则，如果对象来自java包，则返回toString的结果。如果包装失败，则返回null。
