Provides seqan3::nucleotide_alphabet.
Provides seqan3::alphabet_base.
A CRTP-base that makes defining a custom alphabet easier.
Definition: alphabet_base.hpp:57
constexpr rank_type to_rank() const noexcept
Return the letter's numeric value (rank in the alphabet).
Definition: alphabet_base.hpp:139
detail::min_viable_uint_t< size - 1 > rank_type
The type of the alphabet when represented as a number (e.g. via to_rank()).
Definition: alphabet_base.hpp:80
static constexpr detail::min_viable_uint_t< size > alphabet_size
The size of the alphabet, i.e. the number of different values it can take.
Definition: alphabet_base.hpp:203
std::conditional_t< std::same_as< char, void >, char, char > char_type
The char representation; conditional needed to make semi alphabet definitions legal.
Definition: alphabet_base.hpp:72
A CRTP-base that refines seqan3::alphabet_base and is used by the nucleotides.
Definition: nucleotide_base.hpp:43
static constexpr bool char_is_valid(char_type const c) noexcept
Validate whether a character value has a one-to-one mapping to an alphabet value.
Definition: nucleotide_base.hpp:142
constexpr derived_type complement() const noexcept
Return the complement of the letter.
Definition: nucleotide_base.hpp:115
constexpr nucleotide_base(other_nucl_type const &other) noexcept

Definition: nucleotide_base.hpp:86
constexpr auto alphabet_size
A type trait that holds the size of a (semi-)alphabet.
Definition: concept.hpp:861
constexpr auto to_rank
Return the rank representation of a (semi-)alphabet object.
Definition: concept.hpp:155
A concept that indicates whether an alphabet represents nucleotides.
The main SeqAn3 namespace.
Definition: cigar_operation_table.hpp:2
constexpr char_type to_lower(char_type const c) noexcept
Converts 'A'-'Z' to 'a'-'z' respectively; other characters are returned as is.
