Detailed Description

The four letter RNA alphabet of A,C,G,U.

.

This alphabet has the same internal representation as bio::alphabet::dna4, the only difference is that it prints 'U' on character conversion instead of 'T'. You can assign between values of bio::alphabet::dna4 and bio::alphabet::rna4.

Like most alphabets, this alphabet cannot be initialised directly from its character representation. Instead initialise/assign from the character literal or use the function bio::alphabet::rna4::assign_char().

#include <bio/alphabet/nucleotide/rna4.hpp>
#include <bio/alphabet/fmt.hpp>
 
int main()
{
    using namespace bio::alphabet::literals;
 
    bio::alphabet::rna4 my_letter{'A'_rna4};
 
    my_letter.assign_char('C');
 
    my_letter.assign_char('F'); // unknown characters are implicitly converted to A.
    if (my_letter.to_char() == 'A')
        fmt::print("{}", "yeah\n"); // "yeah";
}

Member Function Documentation

assign_char()

template<typename derived_type , size_t size, typename char_t = char>

constexpr derived_type & bio::alphabet::base< derived_type, size, char_t >::assign_char ( char_type const  c )

inlineconstexprnoexceptinherited

Assign from a character, implicitly converts invalid characters.

Parameters

c	The character to be assigned.

Provides an implementation for bio::alphabet::assign_char_to, required to model bio::alphabet::alphabet.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

assign_rank()

template<typename derived_type , size_t size, typename char_t = char>

constexpr derived_type & bio::alphabet::base< derived_type, size, char_t >::assign_rank ( rank_type const  c )

inlineconstexprnoexceptinherited

Assign from a numeric value.

Parameters

c	The rank to be assigned.

Provides an implementation for bio::alphabet::assign_rank_to, required to model bio::alphabet::semialphabet.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

char_is_valid()

static constexpr bool bio::alphabet::nucleotide_base< rna4 , size >::char_is_valid ( char_type const  c )

inlinestaticconstexprnoexceptinherited

Validate whether a character value has a one-to-one mapping to an alphabet value.

Satisfies the bio::alphabet::semialphabet::char_is_valid_for() requirement via the bio::alphabet::char_is_valid_for() wrapper.

Behaviour specific to nucleotides: True also for lower case letters that silently convert to their upper case and true also for U/T respectively, e.g. 'U' is a valid character for bio::alphabet::dna4, because its informational content is identical to 'T'.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

to_char()

template<typename derived_type , size_t size, typename char_t = char>

constexpr char_type bio::alphabet::base< derived_type, size, char_t >::to_char ( ) const

inlineconstexprnoexceptinherited

Return the letter as a character of char_type.

Provides an implementation for bio::alphabet::to_char, required to model bio::alphabet::alphabet.

Complexity

Constant.

Exceptions

Guaranteed not to throw.

to_rank()

template<typename derived_type , size_t size, typename char_t = char>

constexpr rank_type bio::alphabet::base< derived_type, size, char_t >::to_rank ( ) const

inlineconstexprnoexceptinherited

Return the letter's numeric value (rank in the alphabet).

Provides an implementation for bio::alphabet::to_rank, required to model bio::alphabet::semialphabet.

Complexity

Constant.

Exceptions

Guaranteed not to throw.
