Examples

Simple decoding and encoding:

LoRDeck deck = LoRDeckCoder.toDeck("CEBAIAIFB4WDANQIAEAQGDAUDAQSIJZUAIAQCBIFAEAQCBAA");

String code = LoRDeckCoder.toCode(deck, FormatVersion.LIVE);

Parsing and fetching card codes:

LoRCard card = LoRCard.fromCardCode("01PZ019");	
	
String cardCode = card.getCardCode();
LoRFaction faction = card.getFaction();

Deck manipulation and analysis:

deck.addCards(LoRCard.fromCardCode("01PZ019"), 2);

int freljordCards = deck.getCards().entrySet().stream()
        .filter(e -> e.getKey().getFaction() == LoRFaction.FRELJORD)
        .mapToInt(Map.Entry::getValue)
        .sum();

Custom decoder if you prefer your own implementation:

LoRDeck customDeck = LoRCoder.decode(code, LoRDecoder.from(
        LoRDeck::new,
        (deck, set, factionId, cardNumber, amount) ->
            deck.addCards(new LoRCard(set, factionId, cardNumber), amount)
));

Implementation Details

• All operations on the default implementation objects (LoRDeck, LoRCard) are safe. This means a deck or card cannot be in an invalid state and is thus always encodable
