Detailed Description

template<typename _CharT, typename _ValueT>
class CNParamNode< _CharT, _ValueT >

CNParamNode represents functions that take any number of parameters.

For example SUM(P1, P2, P3, P4, .... ,PN)

Member Data Documentation

template<typename _CharT , typename _ValueT >

CNode<_ValueT>** CNParamNode< _CharT, _ValueT >::nodes

Nodes that represent the parameters of this function node.

For example X,Y,Z in SUM(X,Y,Z).

template<typename _CharT , typename _ValueT >

CMathParser<_CharT,_ValueT>* CNParamNode< _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.
