Detailed Description

Represents Exclude selector in NDN Interest.

NDN Packet Format v0.3 defines name component types other than GenericNameComponent and ImplicitSha256DigestComponent, and removes Exclude selector. This implementation follows v0.2 semantics and can only store GenericNameComponent and ImplicitSha256DigestComponent. The behavior of isExcluded on a name component of other types is unspecified.

Definition at line 43 of file exclude.hpp.

Member Typedef Documentation

◆ ExcludeMap

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.
