Detailed Description

The validator which can be set up via a configuration file.

Note: For command Interest validation, this policy must be combined with ValidationPolicyCommandInterest, in order to guard against replay attacks.; This policy does not support inner policies (a sole policy or a terminal inner policy)

void ndn::security::v2::validator_config::ValidationPolicyConfig::checkPolicy	(	const Data &	data,

	)

overrideprotectedvirtual

Check data against the policy.

Depending on implementation of the policy, this check can be done synchronously or asynchronously.

Semantics of checkPolicy has changed from v1::Validator

If packet violates policy, the policy should call state->fail with appropriate error code and error description.
If packet conforms to the policy and no further key retrievals are necessary, the policy should call continueValidation(state, nullptr)
If packet conforms to the policy and a key needs to be fetched, the policy should call continueValidation(state, <appropriate-key-request-instance>)

Implements ndn::security::v2::ValidationPolicy.
