inline

Definition at line 54 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.

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 ( )

inlinestaticconstexpr

Maximum number of components in a FIB entry prefix.

Definition at line 88 of file fib.hpp.

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

insert()

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

(

const Name &

prefix

)

Find or insert a FIB entry.

Parameters

prefix

FIB entry name; it must not have more than getMaxDepth() components.

Returns

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

addOrUpdateNextHop()

void nfd::fib::Fib::addOrUpdateNextHop	(	Entry &	entry,
		Face &	face,
		uint64_t	cost
	)

Add a NextHop record.

If a NextHop record for face already exists in entry, its cost is set to cost.

Definition at line 136 of file fib.cpp.

References afterNewNextHop, and nfd::fib::Entry::getPrefix().

removeNextHop()

Fib::RemoveNextHopResult nfd::fib::Fib::removeNextHop	(	Entry &	entry,

	)

Remove the NextHop record for face from entry.

begin()

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

Returns

an iterator to the beginning

Note

The iteration order is implementation-defined.

Warning

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

Definition at line 134 of file fib.hpp.

end()

Returns

an iterator to the end
