本文整理了Java中net.sf.ehcache.Cache.getSize()方法的一些代码示例,展示了Cache.getSize()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。Cache.getSize()方法的具体详情如下:
包路径:net.sf.ehcache.Cache
类名称:Cache
方法名:getSize

Cache.getSize介绍

[英]Gets the size of the cache. This is a subtle concept. See below.

This number is the actual number of elements, including expired elements that have not been removed.

Expired elements are removed from the the memory store when getting an expired element, or when attempting to spool an expired element to disk.

Expired elements are removed from the disk store when getting an expired element, or when the expiry thread runs, which is once every five minutes.

To get an exact size, which would exclude expired elements, use #getKeysWithExpiryCheck().size(), although see that method for the approximate time that would take.

To get a very fast result, use #getKeysNoDuplicateCheck().size(). If the disk store is being used, there will be some duplicates.

Note:getSize() is a very expensive operation in off-heap, disk and Terracotta implementations.
[中]获取缓存的大小。这是一个微妙的概念。见下文。
此数字是元素的实际数量,包括尚未删除的过期元素。
获取过期元素或尝试将过期元素假脱机到磁盘时,将从内存存储中删除过期元素。
获取过期元素时,或当过期线程运行时(每五分钟一次),会从磁盘存储中删除过期元素。
要获得排除过期元素的确切大小,请使用#getKeysWithExpiryCheck()。size(),但请参阅该方法以了解所需的大致时间。
要获得非常快速的结果,请使用#GetKeysNodeUpplicateCheck()。大小()。如果正在使用磁盘存储,则会有一些重复项。
注意:getSize()在堆外、磁盘和Terracotta实现中是一个非常昂贵的操作。
