package req nx nx::Class create summation { :method init {} {set :v 0} :public method add {x} {incr :v $x} :public method value {} {return ${:v}} :public method destroy {} {puts "ended with value [:value]"; next} }
Demonstrating the behavior in a shell:
% set sum [summation new] % $sum value 0 % $sum add 1 1 % $sum add 2 3 % $sum add 3 6 % $sum add 4 10 % $sum value 10
During the destroy of the object, ended with value 10 is printed
% $sum destroy
