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.

inline

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

setDefaultStrategy()

void nfd::strategy_choice::StrategyChoice::setDefaultStrategy

(

const Name &

strategyName

)

set the default strategy

This must be called by forwarder constructor.

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

)

make prefix to inherit strategy from its parent

not allowed for root prefix (ndn:/)

const

get strategy Name of prefix

Returns

true and strategyName at exact match, or false

Definition at line 203 of file strategy-choice.cpp.

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.
