Member Function Documentation

template<typename T >

template<typename U >

void fmt::Buffer< T >::append	(	const U *	begin,
		const U *	end
	)

Appends data to the end of the buffer.

 {
 std::size_t new_size = size_ + internal::to_unsigned(end - begin);
 if (new_size > capacity_)
 grow(new_size);
 std::uninitialized_copy(begin, end,
 internal::make_ptr(ptr_, capacity_) + size_);
 size_ = new_size;
}

template<typename T>

std::size_t fmt::Buffer< T >::capacity ( ) const

inline

Returns the capacity of this buffer.

{ return capacity_; }

template<typename T>

virtual void fmt::Buffer< T >::grow ( std::size_t  size )

protectedpure virtual

Increases the buffer capacity to hold at least size elements updating ptr_ and capacity_.

Implemented in fmt::internal::FixedBuffer< Char >, fmt::internal::MemoryBuffer< T, SIZE, Allocator >, and fmt::internal::MemoryBuffer< Char, internal::INLINE_BUFFER_SIZE, Allocator >.

 }

Here is the caller graph for this function:

template<typename T>

void fmt::Buffer< T >::reserve ( std::size_t  capacity )

inline

Reserves space to store at least capacity elements.

 {
 if (capacity > capacity_)
 grow(capacity);
 }

Here is the caller graph for this function:

template<typename T>

void fmt::Buffer< T >::resize ( std::size_t  new_size )

inline

Resizes the buffer. If T is a POD type new elements may not be initialized.

 {
 if (new_size > capacity_)
 grow(new_size);
 size_ = new_size;
 }

Here is the caller graph for this function:

template<typename T>

std::size_t fmt::Buffer< T >::size ( ) const

inline

Returns the size of this buffer.

{ return size_; }
