I have a difficult problem. I have a method that return an OrderedCollection(an orderedCollection(String),an orderedCollection(String), an orderedCollection(Date)).
I want to have this result an orderedCollection(String, String, Date). How Can i do ?
If your composite collection only includes subcollections with one element, you can use
result := theCollection collect: [:sc| sc first]
where theCollection stands for your OrderedCollection of OrderedCollections.
Otherwise, if the subcollections do not meet this condition and you want to put all elements into a single collection use
result := theCollection gather: [:sc | sc]
For example:
#(#(1) #(2) #(3)) collect: [:sc | sc first]
will give as result the Array #(1 2 3) (similarly for OrderedCollections).
On the other hand
#(#(1 2) #(3) #(4 5 6)) gather: [:sc | sc]
will produce #(1 2 3 4 5 6).
