a Folder

save

public static MemBuf save(Fnt.Folder root)

Generates a MemBuf representing the root folder as a filename table. This is the inverse of load()

Parameters:

root - a Folder object for the root folder

public static void writeFolderToDisk(File dir,
 Fnt.Folder folder,
 ArrayList<byte[]> files)
                              throws IOException

writes the ROM's internal filesystem to disk at the specified path

Parameters:

dir - a File representation of the write path

folder - the Folder object to write

files - an ArrayList of byte[]'s containing the file contents of the provided folder

Throws:

IOException - if the specified file's parent directory does not exist.

loadFromDisk

public static Fnt.Folder loadFromDisk(File dir,
 ArrayList<byte[]> files)

Create a Folder from an unpacked filesystem on disk; This also grabs all the binary data for each file.

dir - a File representing the path to the unpacked data dir on disk to process

files - an ArrayList of byte[]'s to fill with the contents of a directory on disk

Returns:

a Folder

Throws:

RuntimeException - if the specified path on disk does not exist or is not a directory
