Member Function Documentation

double calcForcesAndEnergy ( ContextImpl &  context, bool  includeForces, bool  includeEnergy, int  groups  )

virtual

Calculate the force on each particle generated by this ForceImpl and/or this ForceImpl's contribution to the potential energy of the system.

Parameters

context	the context in which the system is being simulated
includeForces	true if forces should be calculated
includeEnergy	true if the energy should be calculated
groups	a set of bit flags for which force groups to include. Group i should be included if (groups&(1<<i)) != 0.

Returns

this force's contribution to the potential energy of the system, or 0 if this force does not contribute to potential energy (or if includeEnergy is false)

Implements ForceImpl.

std::map<std::string, double> getDefaultParameters ( )

inlinevirtual

Get a map containing the default values for all adjustable parameters defined by this ForceImpl.

These parameters and their default values will automatically be added to the Context.

Implements ForceImpl.

std::vector<std::string> getKernelNames ( )

virtual

Get the names of all Kernels used by this Force.

Implements ForceImpl.

const HarmonicAngleForce& getOwner ( ) const

inlinevirtual

Get the Force object from which this ForceImpl was created.

Implements ForceImpl.

void initialize ( ContextImpl &  context )

virtual

This is called after the ForceImpl is created and before updateContextState(), calcForces(), or calcEnergy() is called on it.

This allows it to do any necessary initialization.

Implements ForceImpl.

void updateContextState ( ContextImpl &  context )

inlinevirtual

This method is called at the beginning of each time step.

It give the ForceImpl a chance to modify the state variables (positions, velocities, and parameters) stored in the Context in arbitrary ways before integration is performed.

Parameters

context

the context in which the system is being simulated

Implements ForceImpl.

void updateParametersInContext
