Detailed Description

template<typename derived_type, auto size>
class seqan3::nucleotide_base< derived_type, size >

A CRTP-base that refines seqan3::alphabet_base and is used by the nucleotides.

Template Parameters

derived_type	The CRTP parameter type.
size	The size of the alphabet.

You can use this class to define your own nucleotide alphabet, but types are not required to be based on it to model seqan3::nucleotide_alphabet, it is purely a way to avoid code duplication.

In addition to the requirements of seqan3::alphabet_base, the derived type needs to define the following static member variable (can be private):

• static std::array<THAT_TYPE, alphabet_size> complement_table that defines for every possible rank value the corresponding complement.

This entity is stable. Since version 3.1.
