Detailed Description

template<int NINT, int NFLOAT, int NDOUBLE>
class UTIL::LCFixedObject< NINT, NFLOAT, NDOUBLE >

Template class for fixed size LCGenericObject subclasses.

By inheriting from this class users can very easily implement their own objects.
It uses an instance of LCGenericObjectImpl that holds the data, thus there is no overhead when the data is read from a database or file for copying it to some local structure (Decorator pattern).
This is still an abstract class: subclasses have to implement LCGenericObject::getTypeName() and LCGenericObject::getDataDescription().

Constructor & Destructor Documentation

template<int NINT, int NFLOAT, int NDOUBLE>

UTIL::LCFixedObject< NINT, NFLOAT, NDOUBLE >::LCFixedObject ( LCObject *  obj )

inline

C'tor to be used for elements of LCGenericObjects read from an LCIO file or the database.

Subclasses should 'override' this, e.g.:
Myclass(LCObject* obj) : LCFixedObject(obj) {}
