Detailed Description

Base class for NDN content store.

Particular implementations should implement Lookup, Add, and Print methods

Doxygen introspection did not find any typical Config paths.
No Attributes are defined for this type.

TraceSources

• CacheHits: Trace called every time there is a cache hit
• CacheMisses: Trace called every time there is a cache miss

Member Function Documentation

virtual bool ns3::ndn::ContentStore::Add ( Ptr< const Data >  data )

pure virtual

Add a new content to the content store.

Parameters

header	Fully parsed Data
packet	Fully formed Ndn packet to add to content store (will be copied and stripped down of headers)

Returns

true if an existing entry was updated, false otherwise
