virtual void LibGeoDecomp::HpxSimulator::HpxSimulator< CELL_TYPE, PARTITION, STEPPER >::addSteerer

(

Steerer< CELL_TYPE > *

steerer

)

[inline, virtual]

adds a Steerer which will be called back before simulation steps as specified by the Steerer's period.

The Steerer is assumed to be owned by the Simulator. It will destroy the Steerer upon its death.

Reimplemented from LibGeoDecomp::Simulator< CELL_TYPE >.

virtual void LibGeoDecomp::HpxSimulator::HpxSimulator< CELL_TYPE, PARTITION, STEPPER >::addWriter

(

ParallelWriter< CELL_TYPE > *

writer

)

[inline, virtual]

register writer which will observe the simulation.

The DistributedSimulator will assume that it now owns the ParallelWriter, so it'll delete it upon destruction.

Reimplemented from LibGeoDecomp::DistributedSimulator< CELL_TYPE >.
