Member Function Documentation

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

overridevirtual

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.

void ndn::security::v2::ValidationPolicySimpleHierarchy::checkPolicy ( const Interest &  interest, const shared_ptr< ValidationState > &  state, const ValidationContinuation &  continueValidation  )

overridevirtual

Check interest against the policy.

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

• 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)

virtual void ndn::security::v2::ValidationPolicy::checkPolicy ( const Certificate &  certificate, const shared_ptr< ValidationState > &  state, const ValidationContinuation &  continueValidation  )

inlinevirtualinherited

Check certificate against the policy.

Unless overridden by the policy, this check defaults to checkPolicy(const Data&, ...).

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

ValidationPolicy & ndn::security::v2::ValidationPolicy::getInnerPolicy ( )

inherited

Return the inner policy.

If the inner policy was not set, behavior is undefined.

Definition at line 48 of file validation-policy.cpp.

bool ndn::security::v2::ValidationPolicy::hasInnerPolicy ( ) const

inlineinherited

Check if inner policy is set.

Definition at line 72 of file validation-policy.hpp.

void ndn::security::v2::ValidationPolicy::setInnerPolicy ( unique_ptr< ValidationPolicy >  innerPolicy )

inherited

Set inner policy.

Multiple assignments of the inner policy will create a "chain" of linked policies. The inner policy from the latest invocation of setInnerPolicy will be at the bottom of the policy list.

For example, sequence of this->setInnerPolicy(policy1) and this->setInnerPolicy(policy2), will result in this->m_innerPolicy == policy1, this->m_innerPolicy->m_innerPolicy == policy2', and this->m_innerPolicy->m_innerPolicy->m_innerPolicy == nullptr.

Exceptions

std::invalid_argument

exception, if innerPolicy is nullptr.

Definition at line 29 of file validation-policy.cpp.

void ndn::security::v2::ValidationPolicy::setValidator ( Validator &  validator )

inherited

Set validator to which the policy is associated.
