Constructor & Destructor Documentation

Peek::Peek ( )

explicit

Default constructor of class Peek.

set the attributes of the interest packet and consumer, has been replaced by Peek::Peek(std::string carName)

Peek::Peek

(

std::string

carName

)

Default constructor of class Peek.

set the attributes of the interest packet and consumer, set car name directly.

Parameters

carName

the unique ID of the car

Peek::~Peek

(

)

Member Function Documentation

void Peek::CollectCurrentCarNumber

(

const Block &

block

)

analysis the coming data, find producer's car ID from it.

add producer's car ID into received car filter so as not to receive same data.

Parameters

Block&

block, contain coming data.

Interest Peek::createInterestPacket

(

std::string

m_name

)

ndn method

create the interest packet according to the interest name and attributes we have set.

Parameters

std::string

m_name, the part of interest name, actually the information of received car filter and time stamp.

Returns

the interest packet.

Note

input string must statistify "/filter/Car1/Car2/Car3/123456"

std::string Peek::getDataString

(

const Block &

block

)

convert coming data block to string.

Parameters

Block&

block, contain coming data.

Returns

the data in the form of string.

time::milliseconds Peek::getDefaultInterestLifetime

(

)

ndn method

set default interest life time, 4 seconds.

std::string Peek::getReceivedData

(

)

pass the data information to planner module.

Returns

information of the aim location from other cars.

bool Peek::isDataReceived

(

)

tell planner module whether received data from other cars.

Returns

true - received data through sending interest.

false - Did not receive data back.

void Peek::onData	(	const Interest &	interest,
		Data &	data
	)

ndn method

received data, and add its producer to received car filter. set m_isDataReceived true.

Parameters

interest,the	interest has been sent
data,coming	data

void Peek::onTimeout

(

const Interest &

interest

)

ndn method

hasn't received data back within timeout, execute this. we don't need do something about it because we have implemented a parameter called m_isDataoReceived to tell planner module the result.

Parameters

the	interest has been sent

void Peek::run

(

)

ndn method

the loop continue to send interest, receive data and modify received car filter within m_ttl. will execute here first and call other functions if necessary.

void Peek::setInterestLifetime

(

int

interestLifetime

)

ndn method

set the interest packet life time in case too many packets in the network.

Parameters

interestLiftetime,milliseconds

void Peek::setMaxSuffixComponents

(

int

maxSuffixComponents

)

ndn method

set the max component attribute of the interest.

Parameters

maxSuffixComponents

void Peek::setMinSuffixComponents

(

int

minSuffixComponents

)

ndn method

set the minist component attribute of the interest.

Parameters

minSuffixComponents

void Peek::setMustBeFresh

(

)

void Peek::setPayloadOnly

(

)

ndn method

set the interest packet attribute, analysis the payload only when receiving data.

void Peek::setPrefixName

(

std::string

prefixName

)

ndn method

set the main part of the interest name.

Parameters

std::string

prefixName, input string.

Note

input string must statistify "ndn:/place/74"

void Peek::setRightmostChildSelector

(

)

ndn method

set the Right most Child Selector attribute of the interest. producer will select the most right child pf the prefix name.

void Peek::setTimeout

(

int

timeout

)

ndn method

set waitting time and m_ttl for the consumer, will execute onTimeout if it happens.

Parameters

timeout,milliseconds

void Peek::usage

(

)

introduce kinds of attributes.
