Inheritance diagram for buffer_access_interface:

Public Member Functions
Direct access
get() exposes the active bytes. get(n) prepares space after them without changing size(); fill that space, then commit it with add(n).
virtual unsigned char const *	get () const =0
virtual unsigned char *	get ()=0
virtual unsigned char *	get (size_t write_size)=0
virtual void	add (size_t added)=0
Contents and extent
consume(n) requires n <= size(). clear() retains storage. capacity() includes consumed space that can be reclaimed. Initialize bytes exposed by resize() before reading them.
virtual void	consume (size_t consumed)=0
virtual size_t	size () const =0
virtual void	clear ()=0
virtual void	append (unsigned char const *data, size_t len)=0
virtual size_t	capacity () const =0
virtual void	resize (size_t size)=0

Protected Member Functions

buffer_access_interface &	operator= (buffer_access_interface const &)=default

Detailed Description

Read and modify a contiguous sequence of buffered bytes.

Preparing space, appending, or resizing can move the data and invalidate pointers.
