Hello,
Since Interpolation is so close in intent to MessageFormat, I seems less
confusing to Java (as opposed to Perl) people to use a
MessageFormat-like name. For example MappedMessageFormat is not bad.
Look at java.text.MessageFormat [1], Interpolation seems to do the same
kind of thing. For example [1], with MessageFormat, you can:
Object[] arguments = {
new Integer(7),
new Date(System.currentTimeMillis()),
"a disturbance in the Force"
};
String result = MessageFormat.format(
"At {1,time} on {1,date}, there was {2} on planet
{0,number,integer}.",
arguments);
output: At 12:30 PM on Jul 3, 2053, there was a disturbance
in the Force on planet 7.
The new Interpolation version would be:
Map arguments = HashMap();
valuesMap.put( "time", new Date(System.currentTimeMillis()) );
valuesMap.put( "what", "a disturbance in the Force" );
//etc
String result = Interpolation.interpolate(
"At ${time} on ${date}, there was ${what} on planet ${planet}.",
arguments);
So the added value to MessageFormat is a more flexible way to pass in
arguments (no positional issues). So why call it something oh-so
completely different from MessageFormat which is so close in
functionality? ;-)
The MappedMessageFormat would also have a "format" method, not an
"interpolate".
Thanks,
Gary
