Detailed Description

Subtracts boost variants in order to calculate rate.

Constructor & Destructor Documentation

o2::monitoring::VariantVisitorRate::VariantVisitorRate ( int count )

inline

Creates variant visitor functor

Parameters

count timestamp difference in milliseconds

template<typename T , typename = typename std::enable_if<std::is_arithmetic<T>::value, T>::type>

double o2::monitoring::VariantVisitorRate::operator()	(	const T &	a,
		const T &	b
	)		const

inline

Calculates rate only when two arguments of the same type are passed

template<typename T , typename U >

double o2::monitoring::VariantVisitorRate::operator()	(	const T &	,
		const U &
	)		const

inline

If arguments have different type an exception is raised

Exceptions

MonitoringException
