Trajectory element signals and handles trajectory writing.

The trajectory element is both a signaller and a simulator element.

During signalling phase, it checks whether the current step is a writing step for either the energy or the state (position, velocity, forces) trajectory. It then notifies the signaller clients of the upcoming step.

For the simulator run, the element registers a run function at trajectory writing steps. Trajectory writing is done using a client system - the element only prepares the output struct, and passes it to the clients who write their part of the trajectory.

Member Function Documentation

void gmx::TrajectoryElement::elementSetup ( )

Prepare trajectory writer.

During setup, the trajectory writer will query the writer clients for their callbacks. It will also call the setup methods of the different clients. To be run before the main simulator run, but after all clients were registered.

Implements gmx::ISimulatorElement.

void gmx::TrajectoryElement::elementTeardown ( )

Teardown trajectory writer.

During teardown, the trajectory writer will call the teardown methods of the clients and perform some additional clean-up. To be run after the main simulator run.

Implements gmx::ISimulatorElement.

void gmx::TrajectoryElement::scheduleTask ( Step  step,
Time  time,
const RegisterRunFunction registerRunFunction 

Register run function for step / time.

Registers a trajectory writing function if the current step / time is either a state or energy writing step, as defined by the signaller

stepThe step number
timeThe time
registerRunFunctionFunction allowing to register a run function
