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
prefixthe prefix; it must start with Interest Name, may contain version component, but must not contain segment component
Exceptions
std::invalid_argumentprefix does not start with Interest Name
std::domain_errorappend, 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)

§ end()

void ndn::mgmt::StatusDatasetContext::end ( )

end the response successfully after appending zero or more blocks

Exceptions
std::domain_errorreject 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_errorappend 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
respContent of producer-generated NACK
