<div>Hi Isuru,</div>
<div><br>
</div>
<div>The ContentStore::Add method is called (and which results in calling of the selected ContentStoreImpl<Policy>::Add method) from ndn::ForwardingStrategy (model/fw/<a href="http://ndn-forwarding-strategy.cc" title="http://ndn-forwarding-strategy.cc
Ctrl+Click to follow link">ndn-forwarding-strategy.cc</a>
line 239 and 255).</div>
<div><br>
</div>
<div>Further, ContentStoreImpl<Policy>::Add calls insert method on the underlying policy-based controller, which results in calling policy-specific 'insert' method. For example, if selected policy is Lru, then `insert' method defined in utils/trie/lru-policy.h
line 77-87.</div>

Hi Alex,
<div><br>
</div>
<div>I looked at the both implementations and still not sure how to handle the entries in CS.</div>

<div>Hi Isuru,</div>
<div><br>
</div>
<div>utils/ folder contain general-use policies and model/cs/ folder contain policy that can be used only with ContentStore. I would recommend to start with general-use and just peek at ContentStore-specific policy to see how to access information from cached
entry.</div>

Hi Alex,

</div>
<div>To write a policy which file should I refer to. I noticed the ContentStore implementation in */model/ cs folder and policy file in */utils/ trie folder.</div>
<div>Could you suggest me good way to start to create a new policy.</div>

<div>Hi Isuru,
<div><br>
</div>
<div>Since ContentStore is property of the forwarding daemon, there is no application interface to directly manage (add/remove) entries. You can have full control over the cache content if you write a so-called policy, but this will not be application.</div>
