<P>
|
|
An immutable Cache statistics implementation}
|
|
<p/>
|
|
This is like a value object, with the added ability to clear cache statistics on the cache.
|
|
That ability does not survive any Serialization of this class. On deserialization the cache
|
|
can be considered disconnected.
|
|
<p/>
|
|
The accuracy of these statistics are determined by the value of {#getStatisticsAccuracy()}
|
|
at the time the statistic was computed. This can be changed by setting <A HREF="../../../net/sf/ehcache/Cache.html#setStatisticsAccuracy(int)"><CODE>Cache.setStatisticsAccuracy(int)</CODE></A>.
|
|
<p/>
|
|
Because this class maintains a reference to an Ehcache, any references held to this class will precent the Ehcache
|
|
from getting garbage collected.
|
|
<p/>
|
|
The <A HREF="../../../net/sf/ehcache/Statistics.html#STATISTICS_ACCURACY_BEST_EFFORT"><CODE>STATISTICS_ACCURACY_BEST_EFFORT</CODE></A>, <A HREF="../../../net/sf/ehcache/Statistics.html#STATISTICS_ACCURACY_GUARANTEED"><CODE>STATISTICS_ACCURACY_GUARANTEED</CODE></A> and <A HREF="../../../net/sf/ehcache/Statistics.html#STATISTICS_ACCURACY_NONE"><CODE>STATISTICS_ACCURACY_NONE</CODE></A>

constants have the same values as in JSR107.

|

<DL>
|
|
<DD>Gets the number of elements stored in the cache. Caclulating this can be expensive. Accordingly,
|
|
this method will return three different values, depending on the statistics accuracy setting.
|
|
<h3>Best Effort Size</h3>
|
|
This result is returned when the statistics accuracy setting is <A HREF="../../../net/sf/ehcache/Statistics.html#STATISTICS_ACCURACY_BEST_EFFORT"><CODE>STATISTICS_ACCURACY_BEST_EFFORT</CODE></A>.
|
|
<p/>
|
|
The size is the number of <A HREF="../../../net/sf/ehcache/Element.html" title="class in net.sf.ehcache"><CODE>Element</CODE></A>s in the <A HREF="../../../net/sf/ehcache/store/MemoryStore.html" title="class in net.sf.ehcache.store"><CODE>MemoryStore</CODE></A> plus
|
|
the number of <A HREF="../../../net/sf/ehcache/Element.html" title="class in net.sf.ehcache"><CODE>Element</CODE></A>s in the <A HREF="../../../net/sf/ehcache/store/DiskStore.html" title="class in net.sf.ehcache.store"><CODE>DiskStore</CODE></A>.
|
|
<p/>
|
|
This number is the actual number of elements, including expired elements that have
|
|
not been removed. Any duplicates between stores are accounted for.
|
|
<p/>
|
|
Expired elements are removed from the the memory store when
|
|
getting an expired element, or when attempting to spool an expired element to
|
|
disk.
|
|
<p/>
|
|
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.
|
|
<p/>
|
|
<h3>Guaranteed Accuracy Size</h3>
|
|
This result is returned when the statistics accuracy setting is <A HREF="../../../net/sf/ehcache/Statistics.html#STATISTICS_ACCURACY_GUARANTEED"><CODE>STATISTICS_ACCURACY_GUARANTEED</CODE></A>.
|
|
<p/>
|
|
This method accounts for elements which might be expired or duplicated between stores. It take approximately
|
|
200ms per 1000 elements to execute.
|
|
<h3>Fast but non-accurate Size</h3>
|
|
This result is returned when the statistics accuracy setting is <A HREF="../../../net/sf/ehcache/Statistics.html#STATISTICS_ACCURACY_NONE"><CODE>STATISTICS_ACCURACY_NONE</CODE></A>.
|
|
<p/>
|
|
The number given may contain expired elements. In addition if the DiskStore is used it may contain some double
|
|
counting of elements. It takes 6ms for 1000 elements to execute. Time to execute is O(log n). 50,000 elements take
|
|
36ms.
