Detailed Description

template<class T>
class RWBilateralExchange< T >

RWBilateralExchange is an abstract base class derived from the base class RWExchangeImpl, and is a parent of both the RWMultiplicationExchange and RWDivisionExchange classes. RWBilateralExchange implements the usual method of currency conversion: multiplying or dividing the amount of a source currency by a conversion factor to obtain the equivalent amount in the target currency.

Constructor & Destructor Documentation

RWBilateralExchange() [1/4]

template<class T >

RWBilateralExchange< T >::RWBilateralExchange

(

)

Default constructor. The source and target mnemonic strings are set to null, and the conversion factor is set to zero.

RWBilateralExchange() [2/4]

template<class T >

RWBilateralExchange< T >::RWBilateralExchange

(

const RWBilateralExchange< T > &

)

Copy constructor.

RWBilateralExchange() [3/4]

template<class T >

RWBilateralExchange< T >::RWBilateralExchange	(	const RWCString &	source,
		const RWCString &	target,
		double	f )

Constructs a bilateral exchange object with source currency mnemonic given by source, target currency mnemonic given by target, and source to target conversion factor given by f.

RWBilateralExchange() [4/4]

template<class T >

RWBilateralExchange< T >::RWBilateralExchange

(

const RWExchangeRate &

rate

)

Constructs a bilateral exchange object with source currency, target currency and conversion factor provided by the RWExchangeRate object rate.

Member Function Documentation

conversionFactor()

template<class T >

double RWBilateralExchange< T >::conversionFactor ( ) const

inline

Returns the conversion factor.

exchangeRate()

template<class T >

RWExchangeRate RWBilateralExchange< T >::exchangeRate

(

)

const

operator=()

template<class T >

RWBilateralExchange< T > & RWBilateralExchange< T >::operator=

(

const RWBilateralExchange< T > &

)

Assignment operator.

setConversionFactor()

template<class T >

void RWBilateralExchange< T >::setConversionFactor ( double f )

inline

Sets the conversion factor.

setExchangeRate()

template<class T >

void RWBilateralExchange< T >::setExchangeRate

(

const RWExchangeRate &

rate

)

Sets the source currency, target currency and conversion factor to those contained in rate.
