Version 2.3.1                                    Sun Oct 4 2020                               sc::SCElementOp(3)

       Objects of class SCElementOp are used to perform operations on the elements of matrices.

       When the SCElementOp object is given to the element_op member of a matrix, each block the matrix is
       passed to one of the process, process_base, or process_base members.

virtualRef<SCElementOp>sc::SCElementOp::clone()[virtual]
       Returns a clone of this object. This is needed for multithreaded use of SCElementOp objects that are not
       thread safe. The default implemenation throws an exception.

       Reimplemented in sc::OneBodyIntOp.

   virtualboolsc::SCElementOp::cloneable()[virtual]
       Returns true if this SCElementOp supports the cloneable member. The default implmentation returns false.

       Reimplemented in sc::OneBodyIntOp.

   virtualvoidsc::SCElementOp::collect(constRef<SCElementOp>&)[virtual]
       Multithreaded use of cloneable SCElementOp objects requires that data from cloned objects be collected.
       The default implementation will throw an exception.

       Reimplemented in sc::SCElementKNorm, sc::SCElementSumAbs, sc::SCElementMinAbs, sc::SCElementMaxAbs, and
       sc::SCElementInvert.

   virtualintsc::SCElementOp::has_collect()[virtual]
       If duplicates of the SCElementOp exist (that is, there is more than one node), then if has_collect
       returns nonzero then collect is called with a MessageGrp reference after all of the blocks have been
       processed. The default return value of has_collect is 0 and collect's default action is do nothing. If
       defer_collect member is called with nonzero, collect will do nothing (this is only used by the blocked
       matrices).

       Reimplemented in sc::SCElementKNorm, sc::SCElementSumAbs, sc::SCElementMinAbs, sc::SCElementMaxAbs, and
       sc::SCElementInvert.

   virtualintsc::SCElementOp::has_side_effects()[virtual]
       By default this returns nonzero. If the ElementOp specialization will change any elements of the matrix,
       then this must be overridden to return nonzero.

       Reimplemented in sc::SCElementAccumulateSCVector, sc::SCElementAccumulateDiagSCMatrix,
       sc::SCElementAccumulateSymmSCMatrix, sc::SCElementAccumulateSCMatrix, sc::SCElementDot, sc::OneBodyIntOp,
       sc::SCElementShiftDiagonal, sc::SCElementScaleDiagonal, sc::SCElementInvert, sc::SCElementSquareRoot,
       sc::SCElementAssign, sc::SCElementRandomize, sc::SCElementScale, and sc::LevelShift.

   voidsc::SCElementOp::process_base(SCMatrixBlock*block)
       Lazy matrix implementors can call this member when the type of block specialization is unknown. However,
       this will attempt to dynamic_cast block to a block specialization and will thus be less efficient.

   virtualvoidsc::SCElementOp::process_spec_rect(SCMatrixRectBlock*)[virtual]
       Matrices should call these members when the type of block is known. ElementOp specializations should
       override these when efficiency is important, since these give the most efficient access to the elements
       of the block.

       Reimplemented in sc::OneBodyIntOp.

   virtualboolsc::SCElementOp::threadsafe()[virtual]
       Returns true if this SCElementOp is threadsafe. The default implementation returns false.

       matrices.
