Member Function Documentation

void example::delete_unions	(	void(*)(void *)	delete_label,
		void(*)(void *)	delete_prediction
	)

Example contains unions for label and prediction. These do not get cleaned up by the constructor because the type is not known at that time. To ensure correct cleanup delete_unions must be explicitly called.

example& example::operator= ( const example &  )

delete

example& example::operator= ( example &&  other )
