包路径：net.sf.ehcache.Cache
类名称：Cache
方法名：getKeys

Cache.getKeys介绍

[英]Returns a list of all element keys in the cache, whether or not they are expired.

The returned keys are unique and can almost be considered a set. See net.sf.ehcache.store.CacheKeySet for more details.

The List returned is not live. It is a copy.

The time taken is O(n). On a single CPU 1.8Ghz P4, approximately 8ms is required for each 1000 entries.
[中]返回缓存中所有元素键的列表，无论它们是否过期。
返回的密钥是唯一的，几乎可以视为一个集合。见网。旧金山。ehcache。百货商店有关更多详细信息，请参阅CacheKeySet。
返回的列表不是活动列表。这是一份副本。
所用时间为O（n）。在单CPU 1.8Ghz P4上，每1000个条目大约需要8ms。
