Detailed Description

A custom stream buffer that uses a dynamically resizable std::vector<char> as its underlying storage.

This class inherits from std::streambuf and overrides key virtual functions to provide stream I/O operations on an in-memory buffer. The buffer can grow as needed, and it maintains separate positions for reading (get) and writing (put).

Member Function Documentation

operator=()

memory_buffer & memory_buffer::operator= ( const memory_buffer & )

delete

overflow()

int_type memory_buffer::overflow ( int_type c = traits_type::eof() )

inlineoverrideprotected

Called when a write occurs at or past the end of the put area.

Parameters

c	The character to be written.

Returns

The character c on success, or traits_type::eof() on failure.

seekoff()

pos_type memory_buffer::seekoff ( off_type off, std::ios_base::seekdir dir, std::ios_base::openmode which = std::ios_base::in | std::ios_base::out )

inlineoverrideprotected

Implements seeking to an absolute or relative position. This is the corrected version.

seekpos()

pos_type memory_buffer::seekpos ( pos_type pos, std::ios_base::openmode which = std::ios_base::in | std::ios_base::out )

inlineoverrideprotected

Implements seeking to an absolute position by deferring to seekoff.

str() [1/2]

std::string memory_buffer::str ( ) const

inline

str() [2/2]

void memory_buffer::str ( const std::string & s )

inline

underflow()

int_type memory_buffer::underflow ( )

inlineoverrideprotected

Called when the get area is exhausted. For an in-memory buffer, this means EOF.
