Detailed Description

Validation state for an interest packet.

Definition at line 206 of file validation-state.hpp.

Constructor & Destructor Documentation

◆ InterestValidationState()

ndn::security::InterestValidationState::InterestValidationState ( const Interest interest,
const InterestValidationSuccessCallback successCb,
const InterestValidationFailureCallback failureCb 
)

Create validation state for interest.

The caller must ensure that state instance is valid until validation finishes (i.e., until after validateCertificateChain() and validateOriginalPacket() are called)

Definition at line 126 of file validation-state.cpp.

◆ ~InterestValidationState()

ndn::security::InterestValidationState::~InterestValidationState ( )
final

Destructor.

If neither success callback nor failure callback was called, the destructor will call failure callback with IMPLEMENTATION_ERROR error code.

Definition at line 137 of file validation-state.cpp.

Member Function Documentation

◆ addCertificate()

void ndn::security::ValidationState::addCertificate ( const Certificate cert)
inherited

Add cert to the top of the certificate chain.

If m_certificateChain is empty, cert should be the signer of the original packet. If m_certificateChain is not empty, cert should be the signer of m_certificateChain.front().

Postcondition
m_certificateChain.front() == cert
Note
This function does not verify the signature bits.

Definition at line 47 of file validation-state.cpp.

◆ fail()

void ndn::security::InterestValidationState::fail ( const ValidationError error)
finalvirtual

Call the failure callback.

Implements ndn::security::ValidationState.

Definition at line 169 of file validation-state.cpp.

◆ getDepth()

size_t ndn::security::ValidationState::getDepth ( ) const
inlinenoexceptinherited
Returns
Depth of certificate chain

Definition at line 79 of file validation-state.hpp.

◆ getOriginalInterest()

const Interest& ndn::security::InterestValidationState::getOriginalInterest ( ) const
inline
Returns
Original interest being validated

Definition at line 234 of file validation-state.hpp.

◆ getOutcome()

boost::logic::tribool ndn::security::ValidationState::getOutcome ( ) const
inlinenoexceptinherited

Definition at line 64 of file validation-state.hpp.

◆ getTag()

template<typename T >
std::shared_ptr< T > ndn::TagHost::getTag
inherited

Get a tag item.

Template Parameters
Ttype of the tag, which must be a subclass of ndn::Tag
Return values
nullptrif no Tag of type T is stored

Definition at line 72 of file tag-host.hpp.

◆ hasSeenCertificateName()

bool ndn::security::ValidationState::hasSeenCertificateName ( const Name certName)
inherited

Check if certName has been previously seen and record the supplied name.

Definition at line 41 of file validation-state.cpp.

◆ removeTag()

template<typename T >
void ndn::TagHost::removeTag
inherited

Remove a tag item.

Template Parameters
Ttype of the tag, which must be a subclass of ndn::Tag
Note
Tag can be removed even on a const tag host instance

Definition at line 98 of file tag-host.hpp.

◆ setTag()

template<typename T >
void ndn::TagHost::setTag ( std::shared_ptr< T >  tag) const
inherited

Set (add or replace) a tag item.

Template Parameters
Ttype of the tag, which must be a subclass of ndn::Tag
Note
Tag can be set even on a const tag host instance

Definition at line 84 of file tag-host.hpp.
