Detailed Description

The Parameter and its base classes ParameterTBase and ParameterBase defines an interface to a class derived from the InterfacedBase, through which simple member variables can be manuipulated.

Parameter is templated on the type of the member variable and the type of the InterfacedBase class, and is derived from the InterfaceBase class via ParameterTBase (which is templated only on the type of the member variable) and ParameterBase.

For each InterfacedBase class exactly one static Parameter object should created for each member variable which should be interfaced. This object will automatically register itself with the BaseRepository class.

Constructor & Destructor Documentation

◆ ParameterBase()

ThePEG::ParameterBase::ParameterBase	(	string	newName,
		string	newDescription,
		string	newClassName,
		const type_info &	newTypeInfo,
		bool	depSafe,
		bool	readonly,
		int	limits
	)

inline

Standard constructor.

Parameters

newName	the name of the interface, may only contain letters [a-zA-z0-9_].
newDescription	a brief description of the interface.
newClassName	the name of the corresponding class.
newTypeInfo	the type_info object of the corresponding class.
depSafe	set to true if calls to this interface for one object does not influence other objects.
readonly	if this is set true the interface will not be able to manipulate objects of the corresponding class, but will still be able to access information.
limits	determines if the values of the parameters are limited from above and/or below. The possible values are given by Interface::Limits.

Member Function Documentation

◆ def()

virtual string ThePEG::ParameterBase::def ( const InterfacedBase & ib ) const

pure virtual

Return the default value for the member variable of ib.

Implemented in ThePEG::ParameterTBase< Type >, and ThePEG::ParameterTBase< string >.

◆ exec()

virtual string ThePEG::ParameterBase::exec	(	InterfacedBase &	ib,
		string	action,
		string	arguments
	)		const

virtual

The general interface method overriding the one in InterfaceBase.

For this class, action can be any of "set", "get", "min", "max", "def" and "setdef" and argument should be a something which can be read into a variable through a stringstream with the standard '>>' operator.

Implements ThePEG::InterfaceBase.
