                                     java.nio.file.Path dir)

public static java.util.List<java.nio.file.Path> list(@Nonnull
                                                               java.nio.file.Path dir)

Convenience method to return all paths in a SMALL directory.

DO NOT USE THIS TO TRAVERSE LARGE (multi-thousand inode) DIRECTORIES!

For starters you shouldn't be making directories that big at all, but if you did please use Files#newDirectoryStream(Path) directly in your code.

Parameters:

dir - directory to evaluate

Returns:

all files in that directory

Throws:

java.io.IOException
