Detailed Description

The Measurements table.

The Measurements table is a data structure for forwarding strategies to store per name prefix measurements. A strategy can access this table via fw::Strategy::getMeasurements(), and then place any object that derive from StrategyInfo type onto Measurements entries.

Member Function Documentation

◆ extendLifetime()

void nfd::measurements::Measurements::extendLifetime	(	Entry &	entry,
		const time::nanoseconds &	lifetime
	)

Extend lifetime of an entry.

The entry will be kept until at least now()+lifetime.

Definition at line 126 of file measurements.cpp.

◆ findExactMatch()

Entry * nfd::measurements::Measurements::findExactMatch ( const Name & name ) const

Perform an exact match.

Definition at line 119 of file measurements.cpp.

◆ findLongestPrefixMatch() [1/2]

Entry * nfd::measurements::Measurements::findLongestPrefixMatch	(	const Name &	name,
		const EntryPredicate &	pred = `AnyEntry()`
	)		const

Perform a longest prefix match for name.

Definition at line 107 of file measurements.cpp.

◆ findLongestPrefixMatch() [2/2]

Entry * nfd::measurements::Measurements::findLongestPrefixMatch	(	const pit::Entry &	pitEntry,
		const EntryPredicate &	pred = `AnyEntry()`
	)		const

Perform a longest prefix match for pitEntry.getName().

Definition at line 113 of file measurements.cpp.

◆ get() [1/3]

Entry & nfd::measurements::Measurements::get ( const fib::Entry & fibEntry )

Equivalent to get(fibEntry.getPrefix()).

Definition at line 65 of file measurements.cpp.

◆ get() [2/3]

Entry & nfd::measurements::Measurements::get ( const Name & name )

Find or insert an entry by name.

An entry name can have at most getMaxDepth() components. If name exceeds this limit, it is truncated to the first getMaxDepth() components.

Definition at line 58 of file measurements.cpp.

◆ get() [3/3]

Entry & nfd::measurements::Measurements::get ( const pit::Entry & pitEntry )

Equivalent to get(pitEntry.getName(), std::min(pitEntry.getName().size(), getMaxDepth())).

Definition at line 72 of file measurements.cpp.

◆ getInitialLifetime()

static time::nanoseconds nfd::measurements::Measurements::getInitialLifetime ( )

inlinestatic

Definition at line 142 of file measurements.hpp.

◆ getMaxDepth()

static constexpr size_t nfd::measurements::Measurements::getMaxDepth ( )

inlinestaticconstexpr

Maximum depth of a Measurements entry.

Definition at line 94 of file measurements.hpp.

◆ getParent()

Entry * nfd::measurements::Measurements::getParent ( const Entry & child )

Find or insert a parent entry.

Return values

nullptr child is the root entry

Returns: get(child.getName().getPrefix(-1))

Definition at line 79 of file measurements.cpp.

◆ size()

size_t nfd::measurements::Measurements::size ( ) const

inline
