Member Function Documentation

insert()

void nfd::cs::Cs::insert	(	const Data &	data,
		bool	isUnsolicited = false
	)

inserts a Data packet

find()

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
