Public Member Functions

SCElementKNorm (double k=2.0)
by default compute 2-norm
SCElementKNorm (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 process (SCMatrixBlockIter &)
This is the fallback routine to process blocks and is called by process_spec members that are not overridden.
int has_collect ()
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.
void defer_collect (int)
void collect (const Ref< MessageGrp > &)
void collect (const Ref< SCElementOp > &)
Multithreaded use of cloneable SCElementOp objects requires that data from cloned objects be collected.

void init ()

Member Function Documentation

void sc::SCElementKNorm::collect (const Ref< MessageGrp > &) [virtual]

Reimplemented from sc::SCElementOp.

void sc::SCElementKNorm::collect (const Ref< SCElementOp > &) [virtual]

Multithreaded use of cloneable SCElementOp objects requires that data from cloned objects be collected. The default implementation will throw an exception.

Reimplemented from sc::SCElementOp.

void sc::SCElementKNorm::defer_collect (int) [virtual]

Reimplemented from sc::SCElementOp.

int sc::SCElementKNorm::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 from sc::SCElementOp.

void sc::SCElementKNorm::process (SCMatrixBlockIter &) [virtual]

This is the fallback routine to process blocks and is called by process_spec members that are not overridden.

Implements sc::SCElementOp.

void sc::SCElementKNorm::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.
