arcstk::v_1_0_0::ChecksumSource class
#include <verify.hpp>

Interface: unified access to checksum containers.

A checksum container contains several blocks while each block consists of an ARId and an ordered sequence of checksums. A single checksum is accessed by a block index in combination with the index of the checksum within the block.

A type T can be made available as a ChecksumSource via definig a subclass of ChecksumSourceOf<T>.

Derived classes

template<typename T> class v_1_0_0::ChecksumSourceOf: Wrap a checksum container in a ChecksumSource.
template<typename T> class v_1_0_0::ChecksumSourceOf: Wrap a checksum container in a ChecksumSource.

Constructors, destructors, conversion operators

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

Function documentation

const uint32_t& arcstk::v_1_0_0::ChecksumSource::arcs_value(const size_type block_idx, const size_type track_idx) const

Return the ARCS value on the specified position.

Parameters
block_idx in	0-based block index to access
track_idx in	0-based track index to access
Returns	The ARCS value of the specified index position

Checksum arcstk::v_1_0_0::ChecksumSource::checksum(const size_type block_idx, const size_type track_idx) const

Read checksum on the specified position.

Parameters
block_idx in	0-based block index to access
track_idx in	0-based track index to access
Returns	The checksum of the specified index position

Note that the wrapping of the ARCS value involves a copy.

const unsigned& arcstk::v_1_0_0::ChecksumSource::confidence(const size_type block_idx, const size_type track_idx) const

Read confidence idx in section with the specified block_idx.

Parameters
block_idx in	0-based block index to access
track_idx in	0-based track index to access
Returns	The confidence of the specified index position

const uint32_t& arcstk::v_1_0_0::ChecksumSource::frame450_arcs_value(const size_type block_idx, const size_type track_idx) const

Return the ARCS value of frame 450 on the specified position.

Parameters
block_idx in	0-based block index to access
track_idx in	0-based track index to access
Returns	The ARCS value of frame 450 of the specified index position

ARId arcstk::v_1_0_0::ChecksumSource::id(const size_type block_idx) const

Read id in section with the specified block_idx.

Parameters
block_idx in	0-based block index to access
Returns	The id of the specified block

size_type arcstk::v_1_0_0::ChecksumSource::size() const

Number of blocks.

Returns	Number of blocks in this object

Greatest legal block is size() - 1.

size_type arcstk::v_1_0_0::ChecksumSource::size(const size_type block_idx) const

Size of the block specified by block_idx.

Parameters
block_idx in	0-based block index to access
Returns	The size of the specified block

The number of tracks in this block is its size.
