           Stores an ij pair block of integrals to the file.
       void commit ()
           Commit the content of the accumulator for reading - deactivate the associated MemoryGrp and activate
           the accumulator.
       void activate ()
           Call when ready to start reading content.
       void deactivate ()
           Done reading content - activate the associated MemoryGrp This is a collective operation.

           Retrieves an ij pair block of integrals from the file.
       void release_pair_block (int i, int j, tbint_type oper_type)
           Releases an ij pair block of integrals.
       bool is_local (int i, int j) const
           Is this block stored locally?
       bool is_avail (int i, int j) const
           In this implementation blocks are available only on node 0.
       bool has_access (int proc) const
           Does this task have access to all the integrals?
       bool can_restart () const
           Can restart Node0File-based accumulator.

   void sc::R12IntsAcc_Node0File::commit () [virtual]
       Commit the content of the accumulator for reading - deactivate the associated MemoryGrp and activate the
       accumulator. This is a collective operation.

       Reimplemented from sc::R12IntsAcc.

   void sc::R12IntsAcc_Node0File::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::R12IntsAcc.

   void sc::R12IntsAcc_Node0File::store_memorygrp (Ref< MemoryGrp > & mem, int ni, const size_t blksize = 0)
       [virtual]
       Stores all pair block of integrals held in mem. By default blocks are appended to the end of the same
       file, i.e. they are assumed to have come from consecutive passes of the same transformation. This is a
       collective operation. See documentation for R12IntsAcc::store_memorygrp() for more info.

       Implements sc::R12IntsAcc.
