Prepare an Action for calculation This can be used by Action if they need some special preparation before calculation.

Typical case is for collective variables which would like to change their list of requested atoms. By default (if not overridden) does nothing.

Reimplemented in PLMD::isdb::EMMI, PLMD::multicolvar::MultiColvarBase, PLMD::function::FuncPathMSD, PLMD::generic::DumpMassCharge, PLMD::generic::UpdateIf, PLMD::generic::Print, PLMD::generic::Read, PLMD::bias::ReweightTemperature, PLMD::gridtools::ConvertToFES, PLMD::colvar::Energy, and PLMD::colvar::CoordinationBase.

◆ readAtomsFromPDB()

virtual void PLMD::Action::readAtomsFromPDB ( const PDB )
inlinevirtualinherited

This is overwritten in ActionAtomistic so that we can read the atoms from the pdb input file rather than taking them from the MD code.

Reimplemented in PLMD::ActionAtomistic.

◆ registerKeywords()

void PLMD::bias::Bias::registerKeywords ( Keywords keys)
static

◆ requestArguments()

void PLMD::ActionWithArguments::requestArguments ( const std::vector< Value *> &  arg)
inherited

Setup the dependencies.

◆ runFinalJobs()

virtual void PLMD::Action::runFinalJobs ( )
inlinevirtualinherited

RunFinalJobs This method is called once at the very end of the calculation.

The set of all Actions in run for the final time in forward order.

Reimplemented in PLMD::analysis::Analysis, PLMD::gridtools::ConvertToFES, and PLMD::gridtools::GridPrintingBase.

◆ setBias()

void PLMD::bias::Bias::setBias ( double  bias)
inlineprotected

set the value of the bias

◆ setGradientsIfNeeded()

void PLMD::ActionWithValue::setGradientsIfNeeded ( )
inherited

Calculate the gradients and store them for all the values (need for projections)

◆ setNotPeriodic()

void PLMD::ActionWithValue::setNotPeriodic ( )
inherited

Set your default value to have no periodicity.

◆ setOption()

void PLMD::Action::setOption ( const std::string &  s)
virtualinherited

◆ setOutputForce()

void PLMD::bias::Bias::setOutputForce ( int  i,
double  f 
)
inlineprotected

set the force from the bias on argument i, this automatically set the partial derivative of the bias with respect to i to -f

void PLMD::ActionWithValue::setPeriodic ( const std::string &  min,
const std::string &  max 
)
inherited

Set the value to be periodic with a particular domain.

void PLMD::ActionPilot::setStride ( const int &  n)
inherited

Set the value of the stride.

void PLMD::ActionWithValue::setValue ( const double &  d)
inlineprotectedinherited

Set the default value (the one without name)

◆ setValue() [2/2]

void PLMD::ActionWithValue::setValue ( Value ,
double   
)
inherited

Set the value.

◆ unlockRequests() [2/2]

virtual void PLMD::Action::unlockRequests ( )
inlinevirtualinherited

◆ update()

virtual void PLMD::Action::update ( )
inlinevirtualinherited

◆ useCustomisableComponents()

void PLMD::ActionWithValue::useCustomisableComponents ( Keywords keys)
staticinherited

The components in the action will depend on the user.

◆ useNumericalDerivatives()

void PLMD::ActionWithValue::useNumericalDerivatives ( )
inlineinherited

This forces the class to use numerical derivatives.

◆ warning()

void PLMD::Action::warning ( const std::string &  msg)
inherited

Issue a warning.
