包路径：org.eclipse.ditto.json.JsonObject
类名称：JsonObject
方法名：toBuilder

JsonObject.toBuilder介绍

[英]Returns a new mutable builder with a fluent API for a JsonObject. The returned builder is already initialised with the data of the this JSON object. This method is useful if an existing JSON object should be strongly modified but the amount of creating objects should be kept low at the same time.
[中]返回一个新的可变生成器，其中包含JsonObject的流畅API。已使用此JSON对象的数据初始化返回的生成器。如果现有的JSON对象应该被强烈修改，但同时创建对象的数量应该保持在较低的水平，则此方法非常有用。
