Detailed Description

template<typename T, typename Int>
class ThePEG::Switch< T, Int >

The Switch class and its base class SwitchBase defines an interface to a class derived from the InterfacedBase, through which simple integer member variables can be manuipulated and set to a pre-defined set of values (options).

Switch is templated on the type of the integer member variable (also enums and bool are allowed) and the type of the class, and is derived from the InterfaceBase class via SwitchBase.

The Switch class has a set of Named SwitchOptions, which limits the values possible to set.

For each InterfacedBase class exactly one static Switch object should created for each member variable which should be interfaced. This object will automatically register itself with the BaseRepository class. Also for each Switch object exactly one static SwitchOption object should be created for each valid integer option.

newDescription	a brief description of the interface.
newMember	a pointer to the member variable. May be null if corresponding set/get functions are provided.
newDef	the default value for the member variable.
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.
newSetFn	optional pointer to the member function for the 'set' action.
newGetFn	optional pointer to the member function for the 'get' action.
newDefFn	optional pointer to the member function for the 'def' action.
