class Foundation_API DirectoryIterator
The DirectoryIterator class is used to enumerate
all files in a directory.
DirectoryIterator has some limitations:
* only forward iteration (++) is supported
* an iterator copied from another one will always
point to the same file as the original iterator,
even is the original iterator has been advanced
(all copies of an iterator share their state with
the original iterator)
* because of this you should only use the prefix
increment operator

public:
DirectoryIterator();
Creates the end iterator.
DirectoryIterator(const std::string& path);
Creates a directory iterator for the given path.
DirectoryIterator(const DirectoryIterator& iterator);
Creates a directory iterator for the given path.
DirectoryIterator(const File& file);
Creates a directory iterator for the given file.
DirectoryIterator(const Path& path);
Creates a directory iterator for the given path.
~DirectoryIterator();
Destroys the DirectoryIterator.
const std::string& name() const;
Returns the current filename.
const Path& path() const;
Returns the current path.

deprecated

Please use the prefix increment operator instead.
