       const Ref< MOIndexSpace > & space2, const std::string & name, double lindep_tol) [static]
       Project space1 on space2. This routine computes X2 such that C1.S12.X2 = I, where I is
       identity matrix and X2 spans subspace of space2. X2 is returned.

       dependencies is returned in nlindep

   void sc::R12IntEvalInfo::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.

   void sc::R12IntEvalInfo::set_absmethod (LinearR12::ABSMethod abs_method)
       Sets the ABS approach to be used (ABS or CABS). Default depends on how the object was
       constructed.

   void sc::R12IntEvalInfo::set_dynamic (bool dynamic) [inline]
       Sets whether to use dynamic load balancing in parallel MO transformations. Default is no

   void sc::R12IntEvalInfo::set_ints_file (const std::string & filename) [inline]
       Sets name of the file used to store transformed integrals. Default depends on how the
       object was constructed.

   void sc::R12IntEvalInfo::set_ints_method (const StoreMethod method) [inline]
       Sets the method of storing transformed MO integrals. Default depends on how the object was
       constructed.

   void sc::R12IntEvalInfo::set_memory (const size_t nbytes)
       Sets the amount of memory to use for the calculation. Default is determined by
       DEFAULT_SC_MEMORY.
