OptionSet.addIfMatch介绍

[英]Adds an ETag to the If-Match options. A byte array of size 0 adds an empty If-Match option, which checks for existence of the targeted resource. Returns the current OptionSet object for a fluent API.
[中]将ETag添加到If Match选项中。大小为0的字节数组添加一个空的If Match选项，该选项检查目标资源是否存在。返回fluent API的当前OptionSet对象。
