Hi
Is there an existing data structure that allow to represent interval
with either open or closed ends like [1 ; 10[.
Class Interval is closed:
1 to: 10
I don't think there is an open interval class.

Hello
Squeak has Interval that represents interval with closed ends.
See the samples below:
(Interval from: 1 to: 10) includes: 2 -- true
(Interval from: 1 to: 10) includes: 10 -- true
(Interval from: 1 to: 10) includes: 11 -- false

Hi
Is there an
Thanks to all who replied to my SimpleSliderMorph question.
I was trying to set the target with the the inspector window as a quick way to
test my program.
Got things working now, thanks!

You can always make subclass of Interval for example OpenedInterval , add
two variables: left and right.Make new methods:
OpenedIntervalfrom: aNumber to: aNumber left: aBoolean
OpenedIntervalfrom: aNumber to: aNumber right: aBoolean
OpenedIntervalfrom: aNumber to: aNumber left: aBoolean right:

Thanks all for these answers... I should have precised I knew about
Interval ;) But you answered all and more. I wanted to be sure they
were no existing implementation of it.
I was also imaginating an implementation of a special kind of interval
(closed + open ends). I have some questions:

Hello Alex,
AC I am trying to design my first GUI using text editor and
AC input field. But I'm a bit confuse on how to append the user input
AC text to text editor in the next line without replacing the current
AC value of text editor.
this is not clear to me.
AC Basically I'm trying to list
(0 to: 1) by: 0.25 equivalent to: # ([0 0,25[ [0 0,5[ [0
0,75[ [0 1])
Of course, I meant:
(0 to: 1) by 0.25 -- #( [0 0,25[ [0,25 0,5[ [0,5 0,75[
[0,75 1]) an array of interval, ie. a discretized
interval
(0 to: 1) leftOpen by: 0.25 -- #( ]0 0,25[

Hmm... When you were talking I wasnt aware of discussion and made up some
basis for this subclass. I send it with this mail.
Now Im gonna work on Intervals arithmetics to each other, for example:
OpenedInterval from: 1 to: 5 right: true sumWith Interval from: 5 to: 8
should give

Interval - I represent a finite arithmetic progression.
What about infinite arithmetic progression ? ;)
Can a collection contain an infinite number of elements... ?
[0 1[ could represent the collection of **all number** between 0 and 1
excluded.
Hi Herbert,
Sorry for not being so clear. I'm trying to design a GUI using input field
where user will input their name and the other part of the GUI is like another
text field to display all the list of user input.
Let's say user input name: Lisa and hit enter button,
the GUI will display:
What do you need it for? As you can see in methods for Interval - there are
two tests for include : rangeIncludes and valueIncludes (includes is both of
them connected).
First checks if a number is beetween borders and second if its enumerated
(with stepping). In deed it contains both:
