Detailed Description

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

Special case to improve performance.

COneParamNode one parameter functions such as SIN(X).

Member Function Documentation

template<typename _CharT , typename _ValueT >

virtual _ValueT COneParamNode< _CharT, _ValueT >::GetValue

(

)

[inline, virtual]

Invoke the underlying function with the proper parameter and return the result.

When the parameter's value is requested, this can trigger a series of GetValue() calls across the expression sub-tree.

Implements CNode< _ValueT >.

Member Data Documentation

template<typename _CharT , typename _ValueT >

CNode<_ValueT>* COneParamNode< _CharT, _ValueT >::Child

The only parameter of this function.

For example X in SIN(X).

template<typename _CharT , typename _ValueT >

CMathParser<_CharT,_ValueT>* COneParamNode< _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.
