virtual RWExchange<T> RWExchangeGroupImpl< T >::getExchange	(	const RWCString &	srcMnemonic,
		const RWCString &	tragetMnemonic,
		const RWExchangeRateTable &	rates
	)			const [pure virtual]

Creates and returns a currency exchange object for converting money in the source currency to money in the target currency using the exchange rates table rates. If the parameters are invalid, the Rogue Wave classes that derive from this class return an invalid exchange object.

Implemented in RWDivisionGroup< T >, RWEuroGroup< T >, and RWMultiplicationGroup< T >.
