Detailed Description

Register holding all the allowed keywords.

This is a register which holds a map between strings (directives) and function pointers. The function pointers are pointing to functions which create an object of the corresponding class given the corresponding options (ActionOptions). There should be only one of there objects allocated. Actions should be registered here at the beginning of execution If the same directive is used for different classes, it is automatically disabled to avoid random results.

Member Function Documentation

void PLMD::ActionRegister::add	(	std::string	key,
		creator_pointer	cp,
		keywords_pointer	kp
	)

Register a new class.

Parameters

key	The name of the directive to be used in the input file
cp	A pointer to a function which creates an object of that class
kp	A pointer to a function which returns the allowed keywords

bool PLMD::ActionRegister::check ( std::string action )

Verify if a directive is present in the register.

Action * PLMD::ActionRegister::create ( const ActionOptions & ao )

Create an Action of the type indicated in the options.

Parameters

ao	object containing information for initialization, such as the full input line, a pointer to PlumedMain, etc

bool PLMD::ActionRegister::printManual ( const std::string & action )

Print out the keywords for an action in html ready for input into the manual.

bool PLMD::ActionRegister::printTemplate	(	const std::string &	action,
		bool	include_optional
	)

Print out a template command for an action.

void PLMD::ActionRegister::remove ( creator_pointer f )

ActionRegister & actionRegister ( )

To avoid problems with order of initialization, this function contains a static ActionRegister which is built the first time the function is called. In this manner, it is always initialized before it's used

std::ostream& operator<<	(	std::ostream &	,
		const ActionRegister &
	)

friend

Write on a stream the list of registered directives.

#define PLUMED_REGISTER_ACTION	(	classname,
		directive
	)

static class  PLUMED_UNIQUENAME(classname##RegisterMe){ \
    static PLMD::Action* create(const PLMD::ActionOptions&ao){return new classname(ao);} \
  public: \
    PLUMED_UNIQUENAME(classname##RegisterMe)(){PLMD::actionRegister().add(directive,create,classname::registerKeywords);} \
    ~PLUMED_UNIQUENAME(classname##RegisterMe)(){PLMD::actionRegister().remove(create);} \
  } PLUMED_UNIQUENAME(classname##RegisterMe);

Shortcut for Action registration.

For easier registration, this file also provides a macro PLUMED_REGISTER_ACTION.

Parameters

classname	the name of the class to be registered
directive	a string containing the corresponding directive This macro should be used in the .cpp file of the corresponding class
