### Public Member Functions

**VWN2LCFunctional** ()\
 Construct a VWN2 functional.  **VWN2LCFunctional** (const **Ref**\< **KeyVal** \> &)\
 Construct a VWN2 functional.  **VWN2LCFunctional** (**StateIn** &)\
 void **save\_data\_state** (**StateOut** &)\
 Save the base classes (with save\_data\_state) and the members in the same order that the **StateIn** CTOR initializes them.  void **point\_lc** (const **PointInputData** &, **PointOutputData** &, double &, double &, double &)\

## Member Function Documentation

### void sc::VWN2LCFunctional::point\_lc (const PointInputData &, PointOutputData &, double &, double &, double &)` [virtual]`

Reimplemented from **sc::VWNLCFunctional**.

### void sc::VWN2LCFunctional::save\_data\_state (StateOut &)` [virtual]`

Save the base classes (with save\_data\_state) and the members in the same order that the **StateIn** CTOR initializes them. This must be implemented by the derived class if the class has data.

Reimplemented from **sc::VWNLCFunctional**.
