Detailed Description

Represents the Strategy Choice table.

The Strategy Choice table maintains available Strategy types, and associates Name prefixes with Strategy types.

Each strategy is identified by a strategyName. It's recommended to include a version number as the last component of strategyName.

A Name prefix is owned by a strategy if a longest prefix match on the Strategy Choice table returns that strategy.

Member Function Documentation

begin()

const_iterator nfd::strategy_choice::StrategyChoice::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 164 of file strategy-choice.hpp.

end()

const_iterator nfd::strategy_choice::StrategyChoice::end ( ) const

inline

Returns

an iterator to the end

begin()

Definition at line 173 of file strategy-choice.hpp.

erase()

void nfd::strategy_choice::StrategyChoice::erase

(

const Name &

prefix

)

Make prefix to inherit strategy from its parent.

Note

Not allowed for root prefix (ndn:/)

Definition at line 140 of file strategy-choice.cpp.

findEffectiveStrategy() [1/3]

Strategy & nfd::strategy_choice::StrategyChoice::findEffectiveStrategy

(

const measurements::Entry &

measurementsEntry

)

const

Get effective strategy for measurementsEntry.

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

Definition at line 202 of file strategy-choice.cpp.

findEffectiveStrategy() [2/3]

Strategy & nfd::strategy_choice::StrategyChoice::findEffectiveStrategy

(

const Name &

prefix

)

const

Get effective strategy for prefix.

Definition at line 190 of file strategy-choice.cpp.

findEffectiveStrategy() [3/3]

Strategy & nfd::strategy_choice::StrategyChoice::findEffectiveStrategy

(

const pit::Entry &

pitEntry

)

const

Get effective strategy for pitEntry.

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

Definition at line 196 of file strategy-choice.cpp.

findEffectiveStrategyImpl()

template<typename K >

Strategy& nfd::strategy_choice::StrategyChoice::findEffectiveStrategyImpl

(

const K &

key

)

const

Definition at line 182 of file strategy-choice.cpp.

get()

std::pair< bool, Name > nfd::strategy_choice::StrategyChoice::get

(

const Name &

prefix

)

const

Get strategy Name of prefix.

Returns

true and strategyName at exact match, or false

Definition at line 165 of file strategy-choice.cpp.

insert()

StrategyChoice::InsertResult nfd::strategy_choice::StrategyChoice::insert	(	const Name &	prefix,
		const Name &	strategyName
	)

Set strategy of prefix to be strategyName.

Parameters

prefix	the name prefix to change strategy
strategyName	strategy instance name, may contain version and parameters; strategy must have been registered

Returns

convertible to true on success; convertible to false on failure

Definition at line 70 of file strategy-choice.cpp.

setDefaultStrategy()

void nfd::strategy_choice::StrategyChoice::setDefaultStrategy

(

const Name &

strategyName

)

Set the default strategy.

This must be called by forwarder constructor.

inline

Definition at line 58 of file strategy-choice.hpp.
