Detailed Description

Validation policy for stop-and-wait command Interests.

See also
https://redmine.named-data.net/projects/ndn-cxx/wiki/CommandInterest

This policy checks the timestamp field of a stop-and-wait command Interest. Signed Interest validation and Data validation requests are delegated to an inner policy.

Member Function Documentation

void ndn::security::v2::ValidationPolicyCommandInterest::checkPolicy ( const Data data,
const shared_ptr< ValidationState > &  state,
const ValidationContinuation continueValidation 
)
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.
