The following example, takes the contents of a file in the form of a string,
|
||||
and searches for all the C++ class declarations in the file. The code will
|
||||
work regardless of the way that <tt class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></tt>
|
||||
work regardless of the way that <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
|
||||
is implemented, for example it could easily be modified to work with the
|
||||
SGI rope class, which uses a non-contiguous storage strategy.
