Subject [jira] Commented: (CONFIGURATION-422) Configuration.getInt() should define its accepted inputs, and should also accept octal
Date Tue, 15 Jun 2010 11:17:25 GMT

    [ https://issues.apache.org/jira/browse/CONFIGURATION-422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12878934#action_12878934

Emmanuel Bourg commented on CONFIGURATION-422:
----------------------------------------------

I'm not sure supporting octal values is a good idea. If people have padded their integer values
with 0 this will break their configurations.

However it might be interesting to support the updated number syntax to come in Java 7 (binary
literals and underscores in numbers)

> I can find no information about the format of the string that Configuration.getInt(String)
accepts. I have determined by experimentation and examining the source that it accepts decimal
integers, and hex integers if preceeded by "0x". This should be explained.
> Also, it is customary for functions which accept decimal and hex to also accept octal.
A string with leading "0" should be parsed as octal.
> This should apply to getByte(), getShort(), and getLong() as well.
