Iterator class for looping over all entries in a Map type Config Node.
Typical usage:
Config config; display->save( config ); // Write display's data into config. for( Config::MapIterator iter = config.mapIterator(); iter.isValid(); iter.advance() ) { QString key = iter.currentKey(); Config child = iter.currentChild(); printf( "key %s has value %s.\n", qPrintable( key ), qPrintable( child.getValue().toString() )); }
Maps are stored in alphabetical order of their keys, and MapIterator uses this same order.

| void rviz::Config::MapIterator::advance | ( | ) |
Advance iterator to next entry.
Definition at line 379 of file config.cpp.
| Config rviz::Config::MapIterator::currentChild | ( | ) |
Return a Config reference to the current map entry.
Definition at line 435 of file config.cpp.
| QString rviz::Config::MapIterator::currentKey | ( | ) |
Return the name of the current map entry.
Definition at line 425 of file config.cpp.
| bool rviz::Config::MapIterator::isValid | ( | ) |
Return true if the iterator currently points to a valid entry, false if not.
This is how you tell if your loop over entries is at the end.

| void rviz::Config::MapIterator::start | ( | ) |
Resets the iterator to the start of the map.
