Re: [eclipse-dev] NLS.bind(...) vs MessageFormat.format(...)

[Markus Keller <markus_keller@xxxxxxxxxx>]

Note that even if the values are plain numbers (int, double, ...), you 
should use MessageFormat.
The difference is that  NLS#bind(..) does not support e.g. locale-specific 
thousands separators.

=> Just assume that the 'binding' parameters of the NLS#bind(..) methods 
are of type 'String', not 'Object',
and then ask yourself whether String#valueOf(..) on the concrete arguments 
would be correct.

Re: [eclipse-dev] NLS.bind(...) vs MessageFormat.format(...)







NLS#bind just substitutes values for {0}, {1}, etc, in a message string. 
That's all it does. If you read the class comment for MessageFormat, you 
will see the "pattern" argument can actually specify a number of things, 
such as locale-specific representation of currencies, dates, etc.  If you 
just want to substitute values into a string, I suggest using NLS 
(simpler, faster). If you want to do anything else such as locale-specific 
representation of numbers, use MessageFormat. I've never come across a 
need for MessageFormat myself, but I believe there is some usage in JFace 
that you could look at.

[eclipse-dev] NLS.bind(...) vs MessageFormat.format(...)








Hi,

I'd like to get some clarification when one method should be used instead 
of the other one.
In API Tools, we are trying to use MessageFormat.format(...), but I didn't 

know and I ended up using NLS.bind(...).

When I was about to "fix" and go with MessageFormat.format from the ICU 
bundle, I made a search for NLS.bind(...) usage and I found many hits. So 
I'd like to know when each method should be used.The documentation inside 
the NLS class mentioned that this is not a replacement for the 
MessageFormat method, but it doesn't really say what kind of limitations 
the NLS method has.

Can someone put some light on this, please?

Thanks,

Olivier
