gmx::RestraintManager Class Referencefinal

#include <gromacs/restraint/manager.h>


Manage the Restraint potentials available for Molecular Dynamics.

A simulation runner owns one manager resource to hold restraint objects used in the simulation. In the case of thread MPI simulations, multiple runner instances will have handles to the same underlying resource. With further factoring of the mdrun call stack, this facility can be combined with others into a simulation context object from which simulation code can retrieve support code for a user-configured simulation.

Calling code provides the manager with a means to access the various required input data to be used when restraints are computed.

This should be generalized as work description and factory functions in Context.

void gmx::RestraintManager::addToSpec ( std::shared_ptr< gmx::IRestraintPotential restraint,
std::string  name 

Obtain the ability to create a restraint MDModule.

Though the name is reminiscent of the evolving idea of a work specification, the Spec here is just a list of restraint modules.

restraintshared ownership of a restraint potential interface.
namekey by which to reference the restraint.
unsigned long gmx::RestraintManager::countRestraints ( )

Get the number of currently managed restraints.

number of restraints.

Only considers the IRestraintPotential objects

std::vector< std::shared_ptr< IRestraintPotential > > gmx::RestraintManager::getRestraints ( ) const

Get a copy of the current set of restraints to be applied.

This function is to be used when launching a simulation to get the restraint handles to bind, so it is not performance sensitive. A new vector is returned with each call because it is unspecified whether the set of handles point to the same objects on all threads or between calls to getRestraints.

a copy of the list of restraint potentials.
