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 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 127 of file measurements.cpp.

findExactMatch()

Entry * nfd::measurements::Measurements::findExactMatch

(

const Name &

name

)

const

Perform an exact match.

Definition at line 120 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 108 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 114 of file measurements.cpp.

get() [1/3]

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 59 of file measurements.cpp.

get() [2/3]

Entry & nfd::measurements::Measurements::get

(

const fib::Entry &

fibEntry

)

Equivalent to get(fibEntry.getPrefix())

Definition at line 66 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 73 of file measurements.cpp.

getInitialLifetime()

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

inlinestatic

Definition at line 136 of file measurements.hpp.

getMaxDepth()

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

inlinestatic

maximum depth of a Measurements entry

Definition at line 88 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))
