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.

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
