Detailed Description

template<detail::constexpr_alphabet alphabet_t>
struct seqan3::detail::is_in_alphabet_type< alphabet_t >

Parse condition that checks if a given value is within the given alphabet alphabet_t.

Template Parameters

alphabet_t

The alphabet type. Must model seqan3::alphabet.

Member Function Documentation

operator()()

bool operator() ( char_type  c )

inherited

predicate function to test if c satisfies the given condition.

Parameters

c	The character to be tested.

Returns

true on success, false otherwise.

Attention

This is a concept requirement, not an actual function (however types satisfying this concept will provide an implementation).
