SYNTAX

This Module is pure OO, exports nothing


METHODS

See also Data::Sofu::Binary for public methods.

All these methods are INTERNAL, not for use outside of this module...

Except pack().

new()

Creates a new Binary Driver using DRIVER or the latest one available.

        require Data::Sofu::Binary;
        $bsofu = Data::Sofu::Binary->new("000_002_000_000"); Taking this driver;
        #You can call it directly:

Encodes a STRING using Encoding and returns it.

packData(DATA,TREE)

Encodes one perl datastructure and its contents and returns it.

packArray(DATA,TREE)

Encodes one perl array and its contents and returns it.

packArray(DATA,TREE)

Encodes one perl hash and its contents and returns it.

pack(TREE,[COMMENTS,[ENCODING,[BYTEORDER,[SOFUMARK]]]])

Packs a structure (TREE) into a string using the Sofu binary file format.

Returns a string representing TREE.

TREE

Perl datastructure to pack. Can be a hash, array or scalar (or array of hashes of hashes of arrays or whatever). Anything NOT a hash will be converted to TREE={Value=>TREE};

It can also be a Data::Sofu::Object or derived (Data::Sofu::Map, Data::Sofu::List, Data::Sofu::Value, Data::Sofu::...). Anything not a Data::Sofu::Map will be converted to one (A Map with one attribute called "Value" that holds TREE).

COMMENTS

Comment hash (as returned by Data::Sofu::getSofucomments() or Data::Sofu->new()->comments() after any file was read).

Can be undef or {}.

ENCODING

Specifies the encoding of the strings in the binary sofu file, which can be:

"0" or "UTF-8"

This is default.

Normal UTF-8 encoding (supports almost all chars)

"1" or "UTF-7"

This is default for byteorder = 7Bit (See below)

7Bit encoding (if your transport stream isn't 8-Bit safe

"2" or "UTF-16"

UTF 16 with byte order mark in EVERY string.

Byteoder depends on your machine

"3" or "UTF-16BE"

No BOM, always BigEndian

"4" or "UTF-16LE"

No BOM, always LittleEndian

"5" or "UTF-32"

UTF-32 with byte order mark in EVERY string.

Byteoder depends on your machine

"6" or "UTF-32BE"

No BOM, always BigEndian

"7" or "UTF-32LE"

No BOM, always LittleEndian

"8","9"

Reserved for future use

"10" or "ascii"

Normal ASCII encoding

Might not support all characters and will warn about that.

"11" or "cp1252"

Windows Codepage 1252

Might not support all characters and will warn about that.

"12" or "latin1"

ISO Latin 1

Might not support all characters and will warn about that.

"13" or "latin9"

ISO Latin 9

Might not support all characters and will warn about that.

"14" or "latin10"

ISO Latin 10

Might not support all characters and will warn about that.

BYTEORDER

Defines how the integers of the binary file are encoded.

undef

Maschine order

This is Default.

BOM is placed to detect the order used.

"LE"

Little Endian

BOM is placed to detect the order used.

Use this to give it to machines which are using Little Endian and have to read the file alot

"BE"

Big Endian

BOM is placed to detect the order used.

Use this to give it to machines which are using Big Endian and have to read the file alot

"7Bit"

Use this byteorder if you can't trust your transport stream to be 8-Bit save.

Encoding is forced to be UTF-7. No byte in the file will be > 127.

BOM is set to 00 00.

"NOFORCE7Bit"

Use this byteorder if you can't trust your transport stream to be 8-Bit save but you want another enconding than UTF-7

Encoding is NOT forced to be UTF-7.

BOM is set to 00 00.

SOFUMARK

Defines how often the string "Sofu" is placed in the file (to tell any user with a text-editor what type of file this one is).

undef

Only place one "Sofu" at the beginning of the file.

This is default.

"0" or ""

Place no string anywhere.

"1" or >1

Place a string on every place it is possible

Warning, the file might get big.

"0.000001" - "0.99999"

Place strings randomly.

NOTE:

Encoding, Byteorder and encoding driver (and Sofumark of course) are saved in the binary file. So you don't need to specify them for reading files, in fact just give them the Data::Sofu's readSofu() and all will be fine.

packObject(TREE,[COMMENTS,[ENCODING,[BYTEORDER,[SOFUMARK]]]])

Same as pack() but for Data::Sofu::Object's only

Will be called by pack().

Comments are taken from COMMENTS and from the Objects itself.

packData(DATA,TREE)

Encodes one Data::Sofu::Object and its contents and returns it.

packList(DATA,TREE)

Encodes one Data::Sofu::List and its contents and returns it.

packMap(DATA,TREE)

Encodes one Data::Sofu::Map and its contents and returns it.

packComment(TREE,ADD)

Packs the comment for (TREE) + ADD and returns it.

packHeader([ENCODING,[BYTEORDER,[SOFUMARK]]])

Packs the header of the file and sets encoding and byteorder
