Hi everybody,
I've a new question, I'm creating a "concatenate attribut" with an aggragator, and I would like to only keep unique values on that concatenate attribut.
At the moment, I've this kind of results "0.1,0.1,0.1,0.2", and I would like to just keep "0.1, 0.2".
I've tried a lot of things, with lists etc... but I failed, to find a way to do that.
Do you have any advice to do that ?
Kind regards,
Nicolas
If it's a list, have you tried the ListDuplicateRemover before concatenating?
Thanks @david_r, no it's not a list.
But I tried to generate a list with the aggregator and then, use a ListDuplicateRemover, but it didn't work
If it's a list, have you tried the ListDuplicateRemover before concatenating?
If it's not a list already then an AttributeSplitter, followed by a ListDuplicateRemover then a ListConcatenator is probably the way to go
Weird, works for me:
Before:
`_list{0}' has value `0.1'
`_list{1}' has value `0.1'
`_list{2}' has value `0.1'
`_list{3}' has value `0.2'
After:
`_concatenated' has value `0.1,0.2'
`_list{0}' has value `0.1'
`_list{1}' has value `0.2'
Since you're having floating point numbers, are you sure they're 100% identical? Remember that e.g. 0.1 and 0.099999 won't be treated as a duplicate by the ListDuplicateRemover.
I tried the same approach and it works for me too:
Just to be sure: your decimal delimiter is not a comma (same as the values delimiter)?
Hi @nmeriotdev, to clarify what happened when you tried the ListDuplicateRemover, can you post the list contents logged by Loggers?
Insert two Loggers before and after the ListDuplicateRemover like this, and run.
Logger: Feature is:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Feature Type: `Logger_LOGGED'
Attribute(encoded: utf-8): `_list{0}.attr' has value `0.1'
Attribute(encoded: utf-8): `_list{1}.attr' has value `0.1'
Attribute(encoded: utf-8): `_list{2}.attr' has value `0.1'
Attribute(encoded: utf-8): `_list{3}.attr' has value `0.2'
Logger_2: Feature is:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Feature Type: `Logger_2_LOGGED'
Attribute(encoded: utf-8): `_list{0}.attr' has value `0.1'
Attribute(encoded: utf-8): `_list{1}.attr' has value `0.2'
Hi,
Sorry I wasn't at the office.
So with your answers I've deleted/create again everything and now it work.
I think I was just missing the list concatenator after the duplicateRemover.
Thanks a lot guys.

Regexp Replace
([^-]*)(-\\1)+($|-)', '\\1\\3')
Change the delimiter to your needs. Objects must be sorted.
