Description:

public class FileEnumerator : Object

Example: List all files in a directory, sync:

private void list_children (File file, string space = "", Cancellable? cancellable = null) throws Error {
FileEnumerator enumerator = file.enumerate_children (
"standard::*",
FileQueryInfoFlags.NOFOLLOW_SYMLINKS,
cancellable);

File subdir = file.resolve_relative_path (info.get_name ());
list_children (subdir, space + " ", cancellable);
} else {

print ("%s %s\n", space, info.get_file_type ().to_string ());
print ("%s %s\n", space, info.get_is_symlink ().to_string ());
print ("%s %s\n", space, info.get_is_hidden ().to_string ());
print ("%s %s\n", space, info.get_is_backup ().to_string ());
print ("%s %"+int64.FORMAT+"\n", space, info.get_size ());
}
}

}
}

} catch (Error e) {

Example: List all files in a directory, async:

public static int main (string[] args) {
File file = File.new_for_path (".");
MainLoop loop = new MainLoop ();

file.enumerate_children_async.begin ("standard::*", FileQueryInfoFlags.NOFOLLOW_SYMLINKS, Priority.DEFAULT, null, (obj, res) => {
try {
FileEnumerator enumerator = file.enumerate_children_async.end (res);
FileInfo info;
while ((info = enumerator.next_file (null)) != null) {
print ("%s\n", info.get_name ());
print ("\t%s\n", info.get_file_type ().to_string ());
print ("\t%s\n", info.get_is_symlink ().to_string ());
print ("\t%s\n", info.get_is_hidden ().to_string ());
print ("\t%s\n", info.get_is_backup ().to_string ());
print ("\t%"+int64.FORMAT+"\n", info.get_size ());
}
} catch (Error e) {
print ("Error: %s\n", e.message);
}

loop.quit ();
});
