// Class description:
|
|
//
|
|
// This class represents a parameter which will be taken by a G4UIcommand
|
|
// object. In case a command is defined by constructing G4UIcmdXXX class,
|
|
// it automatically creates necessary parameter objects, thus the user needs
|
|
// not to create parameter object(s). In case the user wants to create a
|
|
// command directly instantiated by G4UIcommand class, he/she must create
|
|
// a parameter object(s)
