Member Function Documentation

◆ appendToName()

void psync::detail::IBLT::appendToName ( ndn::Name & name ) const

Appends self to name.

Encodes our hash table from uint32_t vector to uint8_t vector We create a uin8_t vector 12 times the size of uint32_t vector We put the first count in first 4 cells, keySum in next 4, and keyCheck in next 4. Repeat for all the other cells of the hash table. Then we append this uint8_t vector to the name.

◆ erase()

void psync::detail::IBLT::erase ( uint32_t key )

Definition at line 132 of file iblt.cpp.

◆ getHashTable()

const std::vector<HashTableEntry>& psync::detail::IBLT::getHashTable ( ) const

inline

Definition at line 128 of file iblt.hpp.

◆ initialize()

void psync::detail::IBLT::initialize ( const ndn::name::Component & ibltName )

Populate the hash table using the vector representation of IBLT.

Parameters

ibltName the Component representation of IBLT

Exceptions

Error if size of values is not compatible with this IBF
