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

findLongestPrefixMatch() [2/3]

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

(

const pit::Entry &

const

performs a longest prefix match

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

Definition at line 69 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 75 of file fib.cpp.

findExactMatch()

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

(

const Name &

prefix

)

performs an exact match lookup

getMaxDepth()

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

inlinestatic

Maximum number of components in a FIB entry prefix.

Definition at line 90 of file fib.hpp.

References nfd::FIB_MAX_DEPTH.

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 have no more than getMaxDepth() components.

Returns

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

begin()

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

inline

Returns

an iterator to the beginning

Note

Iteration order is implementation-defined.

Warning

Definition at line 123 of file fib.hpp.

end()

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

inline

Returns

an iterator to the end
