SYNOPSIS

  use Data::Average::Bounded;

DESCRIPTION

Data::Average::Bounded is a bounded version of Data::Average, which keeps the data size to a predefined size.

METHODS

new(max => $max)

Creates a new Data::Average::Bounded object, bounded by $max.

add($value)

Adds a value to the Data::Average::Bounded set. If the data size exceeds the length specified by 'max' given to the constructor, old elements are popped out of the set to keep the data size.

$value may either be an object that implements a method 'value()' which returns a numerical representation of the object, or a simple scalar.

length()

avg()

Same as Data::Average.
