List of all members.

Public Member Functions

 LineStreamBuf ()
virtual ~LineStreamBuf ()
bool is_text_available () const
string get_line ()
 Extracts the next line of text from the LineStreamBuf, and sets the has_newline() flag according to whether this line had a trailing newline or not.

bool has_newline () const

Protected Member Functions

virtual int overflow (int c)
 Called by the system ostream implementation when its internal buffer is filled, plus one character.

virtual int sync ()
 Called by the system ostream implementation when the buffer should be flushed to output (for instance, on destruction).


Private Member Functions

void write_chars (const char *start, int length)
 An internal function called by sync() and overflow() to store one or more characters written to the stream into the memory buffer.


Private Attributes

string _data
bool _has_newline
