<h1>CachePolicy Class Reference</h1>
<code>from PyKDE4.akonadi import *</code>
<p>
Namespace: Akonadi.CachePolicy<br />
<h2>Detailed Description</h2>
<p>Represents the caching policy for a collection.
</p>
<p>
There is one cache policy per collection, it can either define to
inherit all properties of the policy of the parent collection (the default)
or specify the following values:
</p>
<p>
- The item parts that should be permanently kept locally and are downloaded
during a collection sync (eg. full mail vs. just the headers).
- A time up to which non-permantly cached item parts have to be kept at
least (0 - infinity).
- Whether or not a collection sync is triggered on demand, ie. as soon
as it is accessed by a client.
- An optional time interval for regular collection sync (aka interval
mail check).
</p>
<p>
<pre class="fragment">
Akonadi.CachePolicy policy;
policy.setCacheTimeout( 30 );
policy.setIntervalCheckTime( 20 );
Akonadi.Collection collection = ...
collection.setCachePolicy( policy );
</pre>
</p>
<p>
To do: Do we also need a size limit for the cache as well?
To do: on a POP3 account, is should not be possible to change locally cached parts, find a solution for that
