Detailed Description

Implements the Content Store.

This Content Store implementation consists of a Table and a replacement policy.

The Table is a container ( std::set ) sorted by full Names of stored Data packets. Data packets are wrapped in Entry objects. Each Entry contains the Data packet itself, and a few additional attributes such as when the Data becomes non-fresh.

The replacement policy is implemented in a subclass of Policy.

erase()

template<typename AfterEraseCallback >

void nfd::cs::Cs::erase ( const Name &  prefix, size_t  limit, AfterEraseCallback &&  cb  )

inline

Asynchronously erases entries under prefix.

Template Parameters

AfterEraseCallback

void f(size_t nErased)

Parameters

prefix	name prefix of entries
limit	max number of entries to erase
cb	callback to receive the actual number of erased entries; must not be empty; it may be invoked either before or after erase() returns

Definition at line 64 of file cs.hpp.

find()

template<typename HitCallback , typename MissCallback >

void nfd::cs::Cs::find ( const Interest &  interest, HitCallback &&  hit, MissCallback &&  miss  ) const

inline

Finds the best matching Data packet.

Template Parameters

HitCallback	void f(const Interest&, const Data&)
MissCallback	void f(const Interest&)

Parameters

interest	the Interest for lookup
hit	a callback if a match is found; must not be empty
miss	a callback if there's no match; must not be empty

Note

A lookup invokes either callback exactly once. The callback may be invoked either before or after find() returns
