Detailed Description

provides a context for generating response to a StatusDataset request

Definition at line 36 of file status-dataset-context.hpp.

Member Typedef Documentation

NackSender

typedef std::function<void(const ControlResponse& resp)> ndn::mgmt::StatusDatasetContext::NackSender

Definition at line 97 of file status-dataset-context.hpp.

Constructor & Destructor Documentation

StatusDatasetContext()

ndn::mgmt::StatusDatasetContext::StatusDatasetContext	(	const Interest &	interest,
		const DataSender &	dataSender,
		const NackSender &	nackSender
	)

Definition at line 120 of file status-dataset-context.cpp.

References ndn::Interest::getName(), and setPrefix().

Member Function Documentation

getPrefix()

const Name & ndn::mgmt::StatusDatasetContext::getPrefix

(

)

const

Returns

prefix of Data packets, with version component but without segment component

Definition at line 30 of file status-dataset-context.cpp.

setPrefix()

StatusDatasetContext & ndn::mgmt::StatusDatasetContext::setPrefix

(

const Name &

prefix

)

change prefix of Data packets

Parameters

prefix

the prefix; it must start with Interest Name, may contain version component, but must not contain segment component

Exceptions

std::invalid_argument	prefix does not start with Interest Name
std::domain_error	append, end, or reject has been invoked

StatusDatasetHandler may change the prefix of Data packets with this method, before sending any response. The version component is optional, and will be generated from current timestamp when omitted.

Definition at line 36 of file status-dataset-context.cpp.

References ndn::Name::appendVersion(), ndn::Interest::getName(), and ndn::Name::isPrefixOf().

Referenced by nfd::ForwarderStatusManager::ForwarderStatusManager(), and StatusDatasetContext().

getExpiry()

const time::milliseconds & ndn::mgmt::StatusDatasetContext::getExpiry

(

)

const

Returns

expiration duration for this dataset response

Definition at line 56 of file status-dataset-context.cpp.

setExpiry()

StatusDatasetContext & ndn::mgmt::StatusDatasetContext::setExpiry

(

const time::milliseconds &

expiry

)

set expiration duration

The response will be cached for the specified duration. Incoming Interest that matches a cached response will be satisfied with that response, without invoking StatusDatasetHandler again.

Definition at line 62 of file status-dataset-context.cpp.

Referenced by nfd::ForwarderStatusManager::ForwarderStatusManager().

append()

void ndn::mgmt::StatusDatasetContext::append

(

const Block &

block

)

append a Block to the response

Exceptions

std::domain_error

end or reject has been invoked

Definition at line 69 of file status-dataset-context.cpp.

end()

void ndn::mgmt::StatusDatasetContext::end

(

)

end the response successfully after appending zero or more blocks

Exceptions

std::domain_error

reject has been invoked

Definition at line 95 of file status-dataset-context.cpp.

References ndn::tlv::Content, ndn::encoding::makeBinaryBlock(), and ns3::ndn::Name.

Referenced by nfd::FibManager::FibManager(), nfd::ForwarderStatusManager::ForwarderStatusManager(), nfd::FaceManager::setConfigFile(), and nfd::StrategyChoiceManager::StrategyChoiceManager().

reject()

void ndn::mgmt::StatusDatasetContext::reject

(

const ControlResponse &

resp = ControlResponse().setCode(400)

)

declare the non-existence of a response

Exceptions

std::domain_error

append or end has been invoked

This should be invoked when the incoming Interest is malformed. A producer-generated NACK will be returned to requester.

Parameters

resp	Content of producer-generated NACK
