Detailed Description

template<typename Type>
class cass::MedianCalculator< Type >

statistics calculator for a median

adds the datums to an internal vector, which is sorted using nth_element when getting the median.

Template Parameters

type	of the values for the average, defines the precision

template<typename Type>

static value_type cass::MedianCalculator< Type >::median ( const container_type &  container )

inlinestatic

calculate the mean of a container_type container

a static function so that one can use it without having an object of this class.

copy the container, sort the copied container and retrieve the central element

Returns

the median of the values inside the container

Parameters

container

the container from whos values the median should be calculated

void cass::MedianCalculator< Type >::reset ( )

inline

reset the statistics
