Member Function Documentation

size()

size_t nfd::fib::Fib::size ( ) const

inline

Definition at line 56 of file fib.hpp.

findLongestPrefixMatch() [1/3]

const Entry & nfd::fib::Fib::findLongestPrefixMatch

(

const Name &

prefix

)

const

performs a longest prefix match

Definition at line 62 of file fib.cpp.

Referenced by nfd::fw::Strategy::lookupFib().

findLongestPrefixMatch() [2/3]

const Entry & nfd::fib::Fib::findLongestPrefixMatch

(

const pit::Entry &

pitEntry

)

const

performs a longest prefix match

This is equivalent to .findLongestPrefixMatch(pitEntry.getName())

Definition at line 68 of file fib.cpp.

findLongestPrefixMatch() [3/3]

const Entry & nfd::fib::Fib::findLongestPrefixMatch

(

const measurements::Entry &

measurementsEntry

)

const

performs a longest prefix match

This is equivalent to .findLongestPrefixMatch(measurementsEntry.getName())

Definition at line 74 of file fib.cpp.

findExactMatch()

Entry * nfd::fib::Fib::findExactMatch

(

const Name &

prefix

)

performs an exact match lookup

Definition at line 80 of file fib.cpp.

References nfd::name_tree::NameTree::findExactMatch(), and nfd::name_tree::Entry::getFibEntry().

getMaxDepth()

static constexpr size_t nfd::fib::Fib::getMaxDepth ( )

inlinestatic

Maximum number of components in a FIB entry prefix.

This constant is currently advisory, but will become mandatory later.

Definition at line 92 of file fib.hpp.

References nfd::FIB_MAX_DEPTH, and nfd::name_tree::NameTree::getMaxDepth().

insert()

std::pair< Entry *, bool > nfd::fib::Fib::insert

(

const Name &

prefix

)

inserts a FIB entry for prefix

If an entry for exact same prefix exists, that entry is returned.

Returns

the entry, and true for new entry or false for existing entry

Definition at line 90 of file fib.cpp.

References nfd::name_tree::Entry::getFibEntry(), nfd::name_tree::NameTree::lookup(), and nfd::name_tree::Entry::setFibEntry().

erase() [1/2]

void nfd::fib::Fib::erase

(

const Name &

prefix

)

Definition at line 116 of file fib.cpp.

References nfd::name_tree::NameTree::findExactMatch().

Referenced by erase(), and removeNextHop().

erase() [2/2]

void nfd::fib::Fib::erase

(

const Entry &

entry

)

Definition at line 125 of file fib.cpp.

References erase(), and nfd::name_tree::NameTree::getEntry().

removeNextHop()

void nfd::fib::Fib::removeNextHop	(	Entry &	entry,
		const Face &	face
	)

removes the NextHop record for face

Definition at line 136 of file fib.cpp.

References erase(), nfd::name_tree::NameTree::getEntry(), nfd::fib::Entry::hasNextHops(), and nfd::fib::Entry::removeNextHop().

Referenced by nfd::cleanupOnFaceRemoval().

begin()

const_iterator nfd::fib::Fib::begin ( ) const

inline

Returns

an iterator to the beginning

Note

Iteration order is implementation-defined.

Warning

Undefined behavior may occur if a FIB/PIT/Measurements/StrategyChoice entry is inserted or erased during enumeration.

Definition at line 127 of file fib.hpp.

end()

const_iterator nfd::fib::Fib::end ( ) const

inline

Returns

an iterator to the end
