Member Function Documentation

size()

size_t nfd::Pit::size ( ) const

inline

Returns

number of entries

Referenced by nfd::ForwarderStatusManager::ForwarderStatusManager(), and nfd::Pit::const_iterator::operator++().

find()

shared_ptr< pit::Entry > nfd::Pit::find ( const Interest &  interest ) const

inline

finds a PIT entry for Interest

Parameters

interest

the Interest

Returns

an existing entry with same Name and Selectors; otherwise nullptr

insert()

std::pair< shared_ptr< pit::Entry >, bool > nfd::Pit::insert ( const Interest &  interest )

inline

inserts a PIT entry for Interest

Parameters

interest

the Interest; must be created with make_shared

Returns

a new or existing entry with same Name and Selectors, and true for new entry, false for existing entry

findAllDataMatches()

pit::DataMatchResult nfd::Pit::findAllDataMatches

(

const Data &

data

)

const

performs a Data match

Returns

an iterable of all PIT entries matching data

erase()

void nfd::Pit::erase

(

shared_ptr< pit::Entry >

pitEntry

)

erases a PIT Entry

Definition at line 114 of file pit.cpp.

Referenced by nfd::Forwarder::startProcessNack().

begin()

Pit::const_iterator nfd::Pit::begin

(

)

const

returns an iterator pointing to the first PIT entry

Note

Iteration order is implementation-specific and is undefined

The returned iterator may get invalidated if PIT or another NameTree-based table is modified

Definition at line 126 of file pit.cpp.

References nfd::NameTree::fullEnumerate().

end()

Pit::const_iterator nfd::Pit::end ( ) const

inline

returns an iterator referring to the past-the-end PIT entry

Note

The returned iterator may get invalidated if PIT or another NameTree-based table is modified

Definition at line 178 of file pit.hpp.
