const asn1::EtsiTs103097Certificate * m_cert = nullptr

Detailed Description

Read-only view on a certificate

In contrast to Certificate, a view does not own the certificate data. A view can be created with low overhead as no heavy copying is required.

Definition at line 36 of file certificate.hpp.
