Yes, with a negative argument. Adding the check: (0 > integer or: [255 < integer]) ifTrue: [self error: 'parameter out of range 0..255']. is probably enough. Alexandre On 27 May 2009, at 08:27, Gabriel Cotelli wrote:
The ANSI Specification doesn't mention anything about that the integer must be in some range... the only thing that expects is that (Character codePoint: x) codePoint = x ....
anyway... I can add the verification... but that's not specified in the ANSI... anybody knowns some senders of this? I checked Pharo-Dev and found none.. maybe in the Web Image?
Alexandre, how you obtain an error using value: ? given a negative argument? I tried with values greater than 255 and works in my image...
Tonight I check that
2009/5/27 Alexandre Bergel <Alexandre.Bergel@inria.fr> I went through all the changes proposed by this slice. I am not sure how should I review the code, but here is my try: - the new version of Character class>>codePoint: anInteger seems to have a different behavior: The old (current) code is codePoint: integer "Return a character whose encoding value is integer." #Fundmntl. (0 > integer or: [255 < integer]) ifTrue: [self error: 'parameter out of range 0..255']. ^ CharacterTable at: integer + 1
The new one is: codePoint: anInteger "Just for ANSI Compliance" ^self value: anInteger value: anInteger "Answer the Character whose value is anInteger." anInteger > 255 ifTrue: [^self basicNew setValue: anInteger]. ^ CharacterTable at: anInteger + 1.
At the end an error is raised, but this is not the same.
Was this review useful?
