Detailed Description

template<typename T>
class buffer< T >

A contiguous memory buffer with an optional growing ability.

It is an internal class and shouldn't be used directly, only via ~fmtbasic_memory_buffer.

Member Function Documentation

append()

template<typename T>

template<typename U >

template FMT_API void buffer< T >::append	(	const U *	begin,
		const U *	end
	)

Appends data to the end of the buffer.

capacity()

template<typename T>

constexpr auto buffer< T >::capacity ( ) const -> size_t

inline

Returns the capacity of this buffer.

clear()

template<typename T>

void buffer< T >::clear ( )

inline

Clears this buffer.

data() [1/2]

template<typename T>

FMT_CONSTEXPR auto buffer< T >::data ( ) -> T*

inline

Returns a pointer to the buffer data.

data() [2/2]

template<typename T>

FMT_CONSTEXPR auto buffer< T >::data ( ) const -> const T*

inline

Returns a pointer to the buffer data.

grow()

template<typename T>

virtual FMT_CONSTEXPR20 void buffer< T >::grow ( size_t  capacity )

protectedpure virtual

Increases the buffer capacity to hold at least capacity elements.

Implemented in counting_buffer< T >, iterator_buffer< std::back_insert_iterator< Container >, enable_if_t< is_contiguous< Container >::value, typename Container::value_type > >, iterator_buffer< T *, T >, iterator_buffer< T *, T, fixed_buffer_traits >, and iterator_buffer< OutputIt, T, Traits >.

inlineprotected

Sets the buffer data and capacity.

size()

template<typename T>

constexpr auto buffer< T >::size ( ) const -> size_t

inline

Returns the size of this buffer.
