Member Data Documentation

template<typename _CharT , typename _ValueT >

CNode<_ValueT>* CTwoParamNode< _CharT, _ValueT >::Left

The first parameter of this function.

For example X in POW(X,Y).

template<typename _CharT , typename _ValueT >

CMathParser<_CharT,_ValueT>* CTwoParamNode< _CharT, _ValueT >::pParentParser

Parent parser instance.

Used to call the user defined function implementation. In some cases, a user defined function can make use of the parser instance to solve domain specific problems.

template<typename _CharT , typename _ValueT >

CNode<_ValueT>* CTwoParamNode< _CharT, _ValueT >::Right

The second parameter of this function.

For example Y in POW(X,Y).
