◆ 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::ValidationPolicySignedInterest::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 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::ValidationPolicySignedInterest::checkPolicy	(	const Interest &	interest,
		const shared_ptr< ValidationState > &	state,
		const ValidationContinuation &	continueValidation
	)

overrideprotectedvirtual

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)

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

Definition at line 51 of file validation-policy-signed-interest.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_argument exception, 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.
