Detailed Description

template<class T>
class RWExchangeImpl< T >

RWExchangeImpl is an abstract base class from which all currency implementation classes must derive. Class RWExchange is the handle class, which forwards all conversion requests to its associated implementation class.

Synopsis

#include <rw/currency/exchgimpl.h>

Member Function Documentation

clone()

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 >.

exchange()

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 >.

name()

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 implementation, name() returns RWTriangularExchange::exchangeMethodName.

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

setSource()

template<class T >

void RWExchangeImpl< T >::setSource ( const RWCString & src )

inline

Sets the mnemonic for the source currency.

setTarget()

template<class T >

void RWExchangeImpl< T >::setTarget ( const RWCString & trg )

inline

Sets the mnemonic for the target currency.

source()

template<class T >

RWCString RWExchangeImpl< T >::source ( ) const

inline

Returns the mnemonic for the source currency.

target()

template<class T >

RWCString RWExchangeImpl< T >::target ( ) const

inline

Returns the mnemonic for the target currency.
