arcstk::Verifier class
#include <verify.hpp>

Interface: perform a verification.

A verification is performed by matching actual checksums against some reference checksums. A Verifier declares the interface for this matching process. The actual checksums are passed as constructor arguments in the concrete subclasses. Some Verifier types may return nullptr for their actual_id().

Function perform() does the match against the reference checksums passed as an argument.

Any Verifier can be either strict or not strict. A strict Verifier will produce a verified result only iff there is at least one block in the ChecksumSource that is identical to the list of actual Checksums. Iff the Verifier is not strict, its result will qualify as verified already iff every actual Checksum occurred at least in one block of the ChecksumSource.

Any Verifier is strict() by default.

Derived classes

class AlbumVerifier final: Verifier for a list of checksums accompanied by a ToC.
class TracksetVerifier final: Verifier for a set of checksums without a ToC.

Constructors, destructors, conversion operators

~Verifier() defaulted virtual noexcept: Virtual default destructor.
