class mrpt::system::CDirectoryExplorer

This class allows the enumeration of the files/directories that exist into a given path.

The only existing method is “explore” and returns the list of found files & directories. Refer to the example in /samples/UTILS/directoryExplorer

Methods

static TFileInfoList explore(const std::string& path, const unsigned long mask)

The path of the directory to examine must be passed to this constructor, among the According to the following parameters, the object will collect the list of files, which can be modified later through other methods in this class.

Parameters:

path	The path to examine (IT MUST BE A DIRECTORY), e.g “d:temp", or “/usr/include/”
mask	One or the OR’ed combination of the values “FILE_ATTRIB_ARCHIVE” and “FILE_ATTRIB_DIRECTORY”, depending on what file types do you want in the list (These values are platform-independent).
outList	The list of found files/directories is stored here.

static void explore(
    const std::string& path,
    const unsigned long mask,
    TFileInfoList& outList
    )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

static void sortByName(TFileInfoList& lstFiles, bool ascendingOrder = true)

Sort the file entries by name, in ascending or descending order.

static void filterByExtension(TFileInfoList& lstFiles, const std::string& extension)

Remove from the list of files those whose extension does not coincide (without case) with the given one.

Example: filterByExtension(lst,”txt”);
