Constructor & Destructor Documentation

◆ RandomExchanges()

PLMD::generic::RandomExchanges::RandomExchanges ( const ActionOptions ao)

Member Function Documentation

◆ activate()

void PLMD::Action::activate ( )
virtualinherited

Set action to active.

◆ addDependency()

void PLMD::Action::addDependency ( Action action)
inherited

Specify that this Action depends on another one.

◆ apply()

void PLMD::generic::RandomExchanges::apply ( )
inlineoverridevirtual

Apply an Action.

This method is called one time per step. The set of all Actions is applied in backward order.

Implements PLMD::Action.

◆ beforeUpdate()

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

Before Update.

This is a special method that is called just before the update() method. It can be used by actions that want to do something irrespectively of the fact that update() is active or not. In other words, this is always called, even when action is not active.

Reimplemented in PLMD::generic::UpdateIf.

◆ calculate()

void PLMD::generic::RandomExchanges::calculate ( )
inlineoverridevirtual

Calculate an Action.

This method is called one or more times per step. The set of all Actions is calculated in forward order.

Implements PLMD::Action.

◆ calculateFromPDB()

void PLMD::Action::calculateFromPDB ( const PDB pdb)
inherited

Calculate the action given a pdb file as input.

This is used to initialize things like distance from a point in CV map space given a pdb as an input file

◆ calculateNumericalDerivatives()

void PLMD::Action::calculateNumericalDerivatives ( ActionWithValue a = NULL)
virtualinherited

◆ checkNeedsGradients()

virtual bool PLMD::Action::checkNeedsGradients ( ) const
inlinevirtualinherited

Check if the action needs gradient.

Reimplemented in PLMD::bias::MetaD, PLMD::bias::PBMetaD, and PLMD::generic::DumpProjections.

◆ checkNumericalDerivatives()

virtual bool PLMD::Action::checkNumericalDerivatives ( ) const
inlinevirtualinherited

Check if numerical derivatives should be performed.

Reimplemented in PLMD::ActionWithValue.

◆ checkRead()

void PLMD::Action::checkRead ( )
inherited

Check if Action was properly read.

This checks if Action::line is empty. It must be called after a final Action has been initialized

◆ checkUpdate()

bool PLMD::Action::checkUpdate ( ) const
inherited

Check if action should be updated.

◆ cite()

std::string PLMD::Action::cite ( const std::string &  s)
inherited

Cite a paper see PlumedMain::cite.

◆ clearDependencies()

void PLMD::Action::clearDependencies ( )
inherited

Clear the dependence list for this Action.

◆ clearOptions()

void PLMD::Action::clearOptions ( )
virtualinherited

◆ deactivate()

void PLMD::Action::deactivate ( )
inlinevirtualinherited

Set action to inactive.

◆ error()

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

Crash calculation and print documentation.

◆ exit()

void PLMD::Action::exit ( int  c = 0)
inherited

Exit with error code c.

◆ fclose()

int PLMD::Action::fclose ( FILE *  fp)
inherited

Closes a file opened with Action::fclose().

◆ fflush()

void PLMD::Action::fflush ( )
inherited

Tell to the Action to flush open files.

◆ fopen()

FILE * PLMD::Action::fopen ( const char *  path,
const char *  mode 
)
inherited

Opens a file.

This is similar to plain fopen, but with some extra functionality.

  • When opened for writing, processors other than the one with rank 0 just open /dev/null
  • PlumedMain::fopen is used, so that other tricks may appear (see PlumedMain::fopen)

◆ getCPT()

bool PLMD::Action::getCPT ( ) const
inherited

Return true if we are doing at a checkpoint step.

◆ getDependencies()

const Dependencies& PLMD::Action::getDependencies ( ) const
inlineinherited

Return dependencies.

◆ getDocumentation()

std::string PLMD::Action::getDocumentation ( ) const
virtualinherited

◆ getExchangeStep()

bool PLMD::Action::getExchangeStep ( ) const
inherited

Check if we are on an exchange step.

◆ getKeyword()

std::string PLMD::Action::getKeyword ( const std::string &  key)
inherited

Just read one of the keywords and return the whole thing as a string.

◆ getLabel()

const std::string & PLMD::Action::getLabel ( ) const
inlineinherited

Returns the label.

◆ getName()

const std::string & PLMD::Action::getName ( ) const
inlineinherited

Returns the name.

◆ getRestart()

inlineinherited

Check if an option is on.

◆ lockRequests()

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

◆ parse()

template<class T >
void PLMD::Action::parse ( const std::string &  key,
T &  t 
)
inherited

Parse one keyword as generic type.

◆ parseFlag()

void PLMD::Action::parseFlag ( const std::string &  key,
bool &  t 
)
inherited
