 Constructor to restore **SCExtrapData** from a **StateIn** object.  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.  virtual **SCExtrapData** \* **copy** ()=0\
 Return a copy of this.  virtual void **zero** ()=0\
 Set this to zero.  virtual void **accumulate\_scaled** (double scale, const **Ref**\< **SCExtrapData** \> &)=0\

## Member Function Documentation

### virtual void sc::SCExtrapData::accumulate\_scaled (double scale, const Ref\< SCExtrapData \> &)` [pure virtual]`

The passed **SCExtrapData** is accumulated into this after applying the scaling factor.

Implemented in **sc::SymmSCMatrixSCExtrapData**, **sc::SymmSCMatrix2SCExtrapData**, **sc::SymmSCMatrix4SCExtrapData**, and **sc::SymmSCMatrixNSCExtrapData**.

### virtual SCExtrapData \* sc::SCExtrapData::copy ()` [pure virtual]`

Return a copy of this.

Implemented in **sc::SymmSCMatrixSCExtrapData**, **sc::SymmSCMatrix2SCExtrapData**, **sc::SymmSCMatrix4SCExtrapData**, and **sc::SymmSCMatrixNSCExtrapData**.

### void sc::SCExtrapData::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::SavableState**.

Reimplemented in **sc::SymmSCMatrixSCExtrapData**, **sc::SymmSCMatrix2SCExtrapData**, **sc::SymmSCMatrix4SCExtrapData**, and **sc::SymmSCMatrixNSCExtrapData**.

### virtual void sc::SCExtrapData::zero ()` [pure virtual]`

Set this to zero.

Implemented in **sc::SymmSCMatrixSCExtrapData**, **sc::SymmSCMatrix2SCExtrapData**, **sc::SymmSCMatrix4SCExtrapData**, and **sc::SymmSCMatrixNSCExtrapData**.
