Member Function Documentation

double action_term_integrator::action ( )

inlinevirtualinherited

The current total action of fields updated by this integrator. This is kept constant up to order eps^3.

Reimplemented from integrator_base.

Definition at line 124 of file integrator.h.

void action_term_integrator::draw_gaussian_fields ( )

inlinevirtualinherited

Refresh fields that can be drawn from a gaussian distribution This is needed at the beginning of a trajectory

Reimplemented from integrator_base.

Definition at line 128 of file integrator.h.
