bool ndn::security::v2::validator_config::Rule::check	(	uint32_t	pktType,
		const Name &	pktName,
		const Name &	klName,
		const shared_ptr< ValidationState > &	state
	)		const

check if packet satisfies rule's condition

Parameters

pktType	tlv::Interest or tlv::Data
pktName	packet name, for signed Interests the last two components are not removed
klName	KeyLocator name
state	Validation state

Return values

false	packet violates at least one checker. Will call state::fail() with proper code and message.
true	packet satisfies all checkers, further validation is needed

Exceptions

Error

the supplied pktType doesn't match one for which the rule is designed

unique_ptr< Rule > ndn::security::v2::validator_config::Rule::create ( const ConfigSection &  configSection, const std::string &  configFilename  )

static

create a rule from configuration section

Parameters

configSection	The section containing the definition of checker.
configFilename	The configuration file name.

Returns

a rule created from configuration

bool ndn::security::v2::validator_config::Rule::match	(	uint32_t	pktType,
		const Name &	pktName
	)		const

check if the packet name matches rule's filter

If no filters were added, the rule matches everything.

Parameters

pktType	tlv::Interest or tlv::Data
pktName	packet name, for signed Interests the last two components are not removed

Return values

true	If at least one filter matches pktName
false	If none of the filters match pktName

Exceptions

Error

the supplied pktType doesn't match one for which the rule is designed
