包路径：org.eclipse.californium.core.coap.OptionSet
类名称：OptionSet
方法名：getETags

OptionSet.getETags介绍

[英]Returns the list of ETags. In a response, there MUST only be one ETag that defines the payload or the resource given through the Location-* options. In a request, there can be multiple ETags for validation. The OptionSet uses lazy initialization for this list.
[中]返回ETag的列表。在响应中，必须只有一个ETag定义有效负载或通过Location-*选项提供的资源。在一个请求中，可以有多个ETag进行验证。OptionSet对该列表使用延迟初始化。
