Examples with Tuple games.strategy.util.Tuple used on opensource projects

Example 1 with Tuple

use of games.strategy.util.Tuple in project triplea by triplea-game.

the class GameParser method parseAttachments.

private void parseAttachments(final Element root) throws GameParseException {
    for (final Element current : getChildren("attachment", root)) {
        final String className = current.getAttribute("javaClass");
        final Attachable attachable = findAttachment(current, current.getAttribute("type"));
        final String name = current.getAttribute("name");
        final List<Element> options = getChildren("option", current);
        final IAttachment attachment = new XmlGameElementMapper().getAttachment(className, name, attachable, data).orElseThrow(() -> newGameParseException("Attachment of type " + className + " could not be instantiated"));
        attachable.addAttachment(name, attachment);
        final ArrayList<Tuple<String, String>> attachmentOptionValues = setValues(attachment, options);
        // keep a list of attachment references in the order they were added
        data.addToAttachmentOrderAndValues(Tuple.of(attachment, attachmentOptionValues));
    }
}

Example 2 with Tuple

use of games.strategy.util.Tuple in project triplea by triplea-game.

the class BattleCalculator method sortUnitsForCasualtiesWithSupport.

/**
 * The purpose of this is to return a list in the PERFECT order of which units should be selected to die first,
 * And that means that certain units MUST BE INTERLEAVED.
 * This list assumes that you have already taken any extra hit points away from any 2 hitpoint units.
 * Example: You have a 1 attack Artillery unit that supports, and a 1 attack infantry unit that can receive support.
 * The best selection of units to die is first to take whichever unit has excess, then cut that down til they are both
 * the same size,
 * then to take 1 artillery followed by 1 infantry, followed by 1 artillery, then 1 inf, etc, until everyone is dead.
 * If you just return all infantry followed by all artillery, or the other way around, you will be missing out on some
 * important support
 * provided.
 * (Veqryn)
