Public Member Functions
Requirements for seqan3::detail::char_predicate
You can expect the variable and the predicate function on all types that satisfy seqan3::output_stream_over.
bool	operator() (char_type c)
	predicate function to test if c satisfies the given condition.
static constexpr auto	msg
	Defines the condition msg. The type is deduced from the constant expression in the definition of the variable.

Related Symbols
(Note that these are not member symbols.)
template<char op, typename condition_head_t , typename... condition_ts>
const std::string	condition_message_v
	Defines a compound std::string consisting of all given conditions separated by the operator-name op.

Detailed Description

An internal concept to check if an object fulfills the requirements of a seqan3::detail::char_predicate.

An object of the type must be invocable with a std::integral type and supply a static constexpr msg member of type std::string.

Member Function Documentation

operator()()

bool operator()

(

char_type

c

)

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).
