match()

bool ndn::security::v2::validator_config::Rule::match	(	uint32_t	pktType,
		const Name &	pktName,
		const shared_ptr< ValidationState > &	state
	)		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
state	The associated validation state

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

		tlv::SignatureTypeValue	sigType,
		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
sigType	Signature type
pktName	packet name, for signed Interests the last two components are not removed
klName	KeyLocator name
state	Validation state

Return values

false	packet violates all checkers. fail() will have been called on state with proper code and message.
true	packet satisfies at least one checker, further validation is needed.

Exceptions

Error

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

create()

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
