◆ checkPolicy() [1/3]

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.

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 certificate retrievals are necessary, the policy should call continueValidation(nullptr, state)
  • If packet conforms to the policy and a certificate needs to be fetched, the policy should call continueValidation(<appropriate-cert-request-instance>, state)

Definition at line 139 of file validation-policy.hpp.

◆ checkPolicy() [2/3]

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 certificate retrievals are necessary, the policy should call continueValidation(nullptr, state)
  • If packet conforms to the policy and a certificate needs to be fetched, the policy should call continueValidation(<appropriate-cert-request-instance>, state)

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

◆ checkPolicy() [3/3]

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.

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 certificate retrievals are necessary, the policy should call continueValidation(nullptr, state)
  • If packet conforms to the policy and a certificate needs to be fetched, the policy should call continueValidation(<appropriate-cert-request-instance>, state)

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

Definition at line 56 of file validation-policy-simple-hierarchy.cpp.

◆ getInnerPolicy()

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

Return the inner policy.

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

Definition at line 49 of file validation-policy.cpp.

◆ hasInnerPolicy()

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

Check if inner policy is set.

Definition at line 67 of file validation-policy.hpp.

◆ setInnerPolicy()

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_argumentexception, if innerPolicy is nullptr.

Definition at line 30 of file validation-policy.cpp.

◆ setValidator()

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

Set validator to which the policy is associated.

Definition at line 55 of file validation-policy.cpp.
