Hi,
While working on a state machine work flow, I need a flexible way to
define
event/event handling. Since I came from C# background, so I have come up
event.rb to share with everyone. Welcome for comments.
Here’s the example codes. You can get event.rb from
Competo Solutions, Inc. | Sharing our experience in ever changing tech landscapes.
Thanks!
class CoffeeMaker
include Event
def initialize
event 'brew_ready'
event 'brewing_started'
end
def brew
on_brewing_started('new brew started')
#brewing ...
on_brew_ready('coffee is ready!')
end
end
class CoffeeLover
def get_coffee(*args)
puts “thanks for the coffee!”
end
end
cm = CoffeeMaker.new
cm.brewing_started(‘+s1’) {|*args| puts args}
cm.brew_ready(‘+s2’) {|*args| puts args}
cl = CoffeeLover.new
cm.brew_ready(‘+s3’) {|*args| cl.get_coffee args} # add sink with +
cm.brew
cm.brew_ready(‘-s3’) #remove sink with -
cm.brew
produces …
new brew started
thanks for the coffee!
coffee is ready!
new brew started
coffee is ready!
