Member Function Documentation

template<class T >

virtual RWExchangeImpl<T>* RWExchangeImpl< T >::clone

(

)

const [pure virtual]

Returns a copy of self off the heap.

Implemented in RWDivisionExchange< T >, RWMultiplicationExchange< T >, and RWTriangularExchange< T >.

template<class T >

virtual RWMoney<T> RWExchangeImpl< T >::exchange

(

const RWMoney< T > &

money

)

const [pure virtual]

Pure virtual function for converting money from the source currency to the target currency. If the currency associated with money does not match the source currency for self, an exception will be thrown.

Implemented in RWDivisionExchange< T >, RWMultiplicationExchange< T >, and RWTriangularExchange< T >.

template<class T >

virtual RWCString RWExchangeImpl< T >::name

(

)

const [pure virtual]

Pure virtual function that returns the name of the implementation class. Rogue Wave implementation classes return their static data member exchangeMethodName. For example, when an RWExchange object contains an RWTriangularExchange<T> implementation, name() returns RWTriangularExchange::exchangeMethodName.

Implemented in RWDivisionExchange< T >, RWMultiplicationExchange< T >, and RWTriangularExchange< T >.

template<class T >

void RWExchangeImpl< T >::setSource

(

const RWCString &

src

)

[inline]

Sets the mnemonic for the source currency.

template<class T >

void RWExchangeImpl< T >::setTarget

(

const RWCString &

trg

)

[inline]

Sets the mnemonic for the target currency.

template<class T >

RWCString RWExchangeImpl< T >::source

(

)

const [inline]

Returns the mnemonic for the source currency.

template<class T >

RWCString RWExchangeImpl< T >::target

(

)

const [inline]

Returns the mnemonic for the target currency.
