[jira] Created: (COLLECTIONS-230) CollectionUtils.size(null) should
return 0
CollectionUtils.size(null) should return 0
------------------------------------------
Key: COLLECTIONS-230
URL: http://issues.apache.org/jira/browse/COLLECTIONS-230
Project: Commons Collections
Issue Type: Wish
Affects Versions: 3.2
Reporter: Stepan Koltsov
Hello,
CollectionUtils.size(null) currently throws IllegalArgumentException("Unsupported object type: null"). I think CollectionUtils.size(null) should return 0.
Why?
The aim of library is to minimize the amount of code that uses this library. In my experience, in the most cases null collections can be threated as as zero-length. Current behavior causes the need of many trivial null-checks.
