+1 methods should return one single type of object. The only question: what time should be returned? Or should it be nil? On 03.04.2014, at 11:12, Tudor Girba <tudor@tudorgirba.com> wrote:
Hi,
I just stumbled across a strange piece of code, and I am wondering about the reasons behind it:
FileSystemStore>>creationTime: aPath self nodeAt: aPath ifPresent: [ :entry | ^ self basicCreationTime: entry ] ifAbsent: [ ^ false ].
In what case does returning "false" make sense?
