包路径：net.sf.ehcache.Ehcache
类名称：Ehcache
方法名：calculateInMemorySize

Ehcache.calculateInMemorySize介绍

[英]Gets the size of the memory store for this cache

Warning: This method can be very expensive to run. Allow approximately 1 second per 1MB of entries. Running this method could create liveness problems because the object lock is held for a long period
[中]获取此缓存的内存存储的大小
警告：运行此方法可能非常昂贵。每1MB条目允许大约1秒。运行此方法可能会产生活动性问题，因为对象锁被保持很长时间
