GCache 上的 UnsupportedOperationException

[英]UnsupportedOperationException on GCache

I'm trying to retrieves all entries from a GoogleAppEngine cache.我正在尝试从 GoogleAppEngine 缓存中检索所有条目。 But when I try to call values, it will returns java.lang.UnsupportedOperationException.但是当我尝试调用值时,它会返回 java.lang.UnsupportedOperationException。

How can I get that?我怎么能得到那个?

Sounds like this is a JCache feature that's not supported by the App Engine Java Memcache API.听起来这是 App Engine Java Memcache API 不支持的 JCache 功能。
