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.

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

asynchronously erases entries under prefix

Parameters

prefix	name prefix of entries
limit	max number of entries to erase
cb	callback to receive the actual number of erased entries; it may be empty; it may be invoked either before or after erase() returns

Definition at line 92 of file cs.cpp.

void nfd::cs::Cs::find	(	const Interest &	interest,
		const HitCallback &	hitCallback,
		const MissCallback &	missCallback
	)		const

finds the best matching Data packet

Parameters

interest	the Interest for lookup
hitCallback	a callback if a match is found; must not be empty
missCallback	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
