<hr><a name="_details"></a><h2>Detailed Description</h2>
The table of entires in the client-side cache. This class maintains a table of CacheEntries, and one instance of <a class="el" href="structlibdap_1_1HTTPCacheTable_1_1CacheEntry.html">CacheEntry</a> is made for each item in the cache. When an item is accessed it is either locked for reading or writing. When locked for reading the entry is recorded on a list of read-locked entries. The caller must explicitly free the entry for it to be removed from this list (which is the only way it can be opended for writing). An entry can be accessed by multiple readers but only one writer.<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd>The <a class="el" href="structlibdap_1_1HTTPCacheTable_1_1CacheEntry.html">CacheEntry</a> class used to contain a lock that was used to ensure that the entry was locked during any changes to any of its fields. That has been removed - its now the responsibility of the caller. This change was made because it's likely the caller will need to lock all of the methods that operate on a <a class="el" href="structlibdap_1_1HTTPCacheTable_1_1CacheEntry.html">CacheEntry</a> anyway, so the CacheEntry-specific lock was redundant. </dd></dl>
