Subject [configuration] attribute splitting WAS Re: [jira] Commented: (CONFIGURATION-335) XMLConfiguration: Can't disable attribute splitting
Date Sat, 11 Apr 2009 15:26:57 GMT
(Maybe it's better to have this discussion on the mailing list.)

The implementation of attributes in the experimental branch was probably 
incomplete - the node handlers only supported single attribute values, 
XMLConfiguration still had this splitting code.

As I already pointed out in this ticket, the reason for the 
implementation of attribute splitting was that the configuration API 
allows calling addProperty() multiple times for attribute keys. So an 
attempt was made to map those "artificial" attributes to valid XML. 
However, looking at all the consequences of this implementation, the 
question is whether this is really worth the whole trouble.

So I tend to disable this feature in the experimental branch. In 
addProperty() we can check whether an attribute is to be added that 
already exists and for instance throw a ConfigurationRuntimeException in 
this case.

If somebody has a better solution or other suggestions, please let me know.

Oliver

I don't need this behaviour, but setting setDelimiterParsingDisabled() just changing delimeter
to "|" and not disables attribute trimming.
>> Need either to disable trimming/splitting if setDelimiterParsingDisabled() is set
to TRUE (incompatible change), or add something like setParseAttributesAsIs() that will prevent
attributes to be trimmed and splitted
