Detailed Description

template<typename char_type>
struct seqan3::custom::alphabet< char_type >

Alphabet specific customisations for builtin char types.

Template Parameters

char_type

One of char, char16_t, char32_t or wchar_t.

Member Function Documentation

assign_char_to()

template<typename char_type >

static constexpr char_type& seqan3::custom::alphabet< char_type >::assign_char_to ( char_type const  chr2, char_type &  chr  )

inlinestaticconstexprnoexcept

Assign a char to the char type (same as calling =).

Parameters

[in]	chr2	The char value you wish to assign.
[in,out]	chr	The alphabet letter that you wish to assign to.

Returns

A reference to the alphabet letter you passed in.

assign_rank_to()

template<typename char_type >

static constexpr char_type& seqan3::custom::alphabet< char_type >::assign_rank_to ( decltype(alphabet< char_type >::to_rank(char_type{})) const  rank, char_type &  chr  )

inlinestaticconstexprnoexcept

Assigning a rank to a char is the same as assigning it a numeric value.

Parameters

[in]	rank	The rank value you wish to assign.
[in,out]	chr	The alphabet letter that you wish to assign to.

Returns

A reference to the alphabet letter you passed in.

to_char()

template<typename char_type >

static constexpr char_type seqan3::custom::alphabet< char_type >::to_char ( char_type const  chr )

inlinestaticconstexprnoexcept

Converting char to char is no-op (it will just return the value you pass in).

Parameters

[in]

chr

The alphabet letter that you wish to convert to char (no-op).

Returns

chr.

to_rank()

template<typename char_type >

static constexpr auto seqan3::custom::alphabet< char_type >::to_rank ( char_type const  chr )

inlinestaticconstexprnoexcept

Convert char to rank by casting to an unsigned integral type of same size.

Parameters

[in]

chr

The alphabet letter that you wish to convert to rank.

Returns

The letter's value in the alphabet's rank type (usually a uint*_t).

Member Data Documentation

alphabet_size

template<typename char_type >

constexpr auto seqan3::custom::alphabet< char_type >::alphabet_size

staticconstexpr

Initial value:

=
        detail::min_viable_uint_t<detail::size_in_values_v<char_type>>{detail::size_in_values_v<char_type>}

The number of values the char type can take (e.g. 256 for char).
