The TQMapConstIterator class provides an iterator for <a href="tqmap.html">TQMap</a>.

|
<p> In contrast to <a href="tqmapiterator.html">TQMapIterator</a>, this class is used to iterate over a
|
||
|
13 years ago
|
const map. It does not allow you to modify the values of the map
|
||
|
|
because this would break the const semantics.
