Hi. I was needing something like the SQL select distinct, that doesn't take
into account repeated objects. I didn't found anything useful in Collection,
and thus, I have implemented this:
Collection >> collectDistinct: aBlock
collectDistinct: aBlock
"Evaluate aBlock with each of the receiver's elements as the argument.
Collect the resulting values into a Set, thus repeated objects will not
be present.
Answer the new collection."
| newSet |
newSet := self species new asSet.
self do: [:each | newSet add: (aBlock value: each)].
^ newSet
Is there a better way ? Do you think it make sense to put this in Pharo ?
Cheers
Mariano
