Detailed Description

Represents Exclude selector in NDN Interest.

Definition at line 37 of file exclude.hpp.

Member Typedef Documentation

typedef ExcludeMap::value_type ndn::Exclude::Entry

Definition at line 170 of file exclude.hpp.

typedef std::map<ExcludeComponent, bool, std::greater<ExcludeComponent> > ndn::Exclude::ExcludeMap

a map of exclude entries

Each key, except "negative infinity", is a name component that is excluded. The mapped boolean indicates whether the range between a key and the next greater key is also excluded. If true, the wire encoding shall have an ANY element.

The map is ordered in descending order to simplify isExcluded.

Definition at line 169 of file exclude.hpp.
