Member Function Documentation

Card BasicGameStrategies::highestCard ( const CardSequence & sequence ) const

This finds the highest card in a card sequence based on the cards rank value.

Parameters:

sequence

is the sequence of cards to examine.

Returns:: the highest card found, if no high card is found an empty card is given.

Card BasicGameStrategies::highestCardOfSuit	(	const CardSequence &	sequence,
		Card::Suit	suit
	)			const

This finds the highest cards of a specific suit based on the cards rank value.

Parameters:

	sequence	is the sequence of cards to examine.
	suit	is the suit of the highest card we want.

Returns:: the highest card found, if no high card is found an empty card is given.

Card BasicGameStrategies::highestNonTrumpCard	(	const CardSequence &	sequence,
		Card::Suit	trumpSuit
	)			const

This finds the highest card that is not a trump based on the cards rank value.

Parameters:

	sequence	is the sequence of cards to examine
	trumpSuit	is the suit that is trump in the game.

Returns:: the highest card found, if no high card is found an empty card is given.

Card BasicGameStrategies::lowestCard ( const CardSequence & sequence ) const

This finds the lowest card in a card sequence that is based on rank value.

Parameters:

sequence

is the sequence of cards to examine.

Returns:: the lowest card found, if no card is found an empty card is given.

Card BasicGameStrategies::lowestCardOfSuit	(	const CardSequence &	sequence,
		Card::Suit	suit
	)			const

This finds the lowest card of a specific suit based on rank value.

Parameters:

	sequence	is the sequence of cards to examine.
	suit	is the suit we want the lowest card from.

Returns:: the lowest card found of the specified suit, if no card is found an empty card is given.

Card BasicGameStrategies::lowestNonTrumpCard	(	const CardSequence &	sequence,
		Card::Suit	trumpSuit
	)			const

This finds the lowest card not of a trump suit based on rank value.

Parameters:

	sequence	is the sequence of cards to examine.
	trumpSuit	is the suit we don't want the lowest card to be from.

Returns:: the lowest card found, if no card is found an empty card is given.

Card BasicGameStrategies::nextHighestCard	(	const CardSequence &	sequence,
		const Card &	highCard
	)			const

This finds the highest card that is less than a specific card based on rank value.

Parameters:

	sequence	is the sequence of cards to examine.
	highCard	is the highest card we wish to be below.

Returns:: the highest card found, if no card lower than the high card is found the high card is given.

Card BasicGameStrategies::nextHighestCardOfSuit	(	const CardSequence &	sequence,
		const Card &	highCard,
		Card::Suit	suit
	)			const

This finds the highest card of a specific suit that is less than a specific card based on rank value.

Parameters:

	sequence	is the sequence of cards to examine.
	highCard	is the highest card we wish to be below.
	suit	is the suit of the high card we want.

Returns:: the highest card found, if no card lower than the high card is found the high card is given.

Note:: We assume that the high card and the suit both have the same suit.

int BasicGameStrategies::numberOfCardsHigher	(	const CardSequence &	hand,
		const Card::Rank &	rank
	)			const

Determines the number of cards in a sequence of cards that is higher than a specific card.

Parameters:

	hand	is the sequence of cards to examine.
	rank	is the rank that each card must be greater than.

Returns:: the number of cards in hand that is greater than rank.

int BasicGameStrategies::numberOfCardsOfSuit	(	const CardSequence &	hand,
		const Card::Suit &	suit
	)			const

Determines the number of card in a sequence of cards that has a specific suit.

Parameters:

	hand	is the sequence of cards to examine.
	suit	is the suit that each card must be to be counted.

Returns:: the number of cards in hand that is of the specified suit.

int BasicGameStrategies::randomBid	(	int	minimum,
		int	maximum
	)			const

Makes a random bid in a specified range.

Parameters:

	minimum	is the lowest possible bid.
	maximum	is the highest possible bid.

Returns:: the bid generated.

CardSequence BasicGameStrategies::randomCards	(	int	numberOfCards,
		const CardSequence &	hand,
		const CardSequence &	playSequence
	)			const

Selects cards randomly that are legal to play for the game.

Parameters:

	numberOfCards	is the number of cards to select.
	hand	is the sequence of cards to choose from.

Note:: If there is no legal cards in the hand an infinite loop is created!

Parameters:

playSequence

is the sequence of cards currently in play

Returns:: the cards we have chosen.

CardSequence BasicGameStrategies::randomCardsWithNoLegalChecks	(	int	numberOfCards,
		const CardSequence &	hand
	)			const

Selects cards randomly to play for the game without regards for the rules of the game.

Parameters:

	numberOfCards	is the number of cards to select.
	hand	is the sequence of cards to choose from.

Returns:: the cards we have chosen.

CardSequence BasicGameStrategies::selectCards	(	int	numberOfCards,
		const CardSequence &	hand,
		const CardSequence &	playSequence
	)			const

This selects a specific number of cards from our hand based on what is a legal play.

Parameters:

	numberOfCards	is the number of cards we have to select.
	hand	is the sequence of cards to choose from.
	playSequence	is the sequence of cards currently in play

Returns:: the cards we have chosen.

Exceptions:

KardsGTError

if we cannot select as many cards specified in numberOfCards.

CardSequence BasicGameStrategies::selectCardsWithNoLegalChecks	(	int	numberOfCards,
