//! A character stream manager designed for use with RosterSettings files
|
|
/*! The purpose for this class is to make reading through RosterSettings files,
|
|
which contain a number of different types of strings (some with escapes),
|
|
as well as comments, as painless as possible.
|
|
|
|
The main idea is that GetString() will return \c B_OK and a new string
|
|
until it hits an error or the end of the line, at which point an error
|
|
code is returned. The next call to GetString() starts the cycle over on
|
|
the next line. When the end of the stream is finally hit, kEndOfStream is
|
|
returned.
|
|
|
|
SkipLine() simply moves the position of the stream to the next line, and is
|
|
used when a valid string containing invalid data is discovered in the middle
|
|
of a line.
