A streambuffer abstraction over a fixed array of bytes.
This streambuffer cannot overflow/underflow. Once it has reached its end, attempts to read characters will return trait_type::eof
.
caf::arraybuf< CharT, Traits >::arraybuf | ( | Container & | c | ) |
Constructs an array streambuffer from a container.
c | A contiguous container. |
c.data()
must point to a contiguous sequence of characters having length c.size()
. caf::arraybuf< CharT, Traits >::arraybuf | ( | char_type * | data, |
size_t | size | ||
) |
Constructs an array streambuffer from a raw character sequence.
data | A pointer to the first character. |
size | The length of the character sequence. |
