hello all,
ok, I've managed to write a Java program that will treat input data in a
generic way.
for example, the data for the EUR currency
stringlist cur_EUR year value1 value2
stringlist cur_EUR 2009 EUR-2009-1 EUR-2009-2
stringlist cur_EUR 2010 EUR-2010-1 EUR-2010-2
(
the program will do
context.put("cur_EUR", my_object_that_contains_the_three_data_lines)
)
will be interpreted by
#foreach( $res in $cur_EUR )
#if ($velocityCount > 0)
<td> $res.get_string(0) : $res.get_string(1) :
$res.getColumn("year") </td>
#end
#end
to output the corresponding data in cur_EUR
so far so good...
but what if I want to carry this to one level higher, and do not know in
advance how many currencies will have to be treated?
with the input data
stringrow currencies EUR USD JPY
stringlist cur_EUR year value1 value2
stringlist cur_EUR 2009 EUR-2009-1 EUR-2009-2
stringlist cur_EUR 2010 EUR-2010-1 EUR-2010-2
stringlist cur_USD year value1 value2
stringlist cur_USD 2009 USD-2009-1 USD-2009-2
stringlist cur_USD 2010 USD-2010-1 USD-2010-2
stringlist cur_USD 2011 USD-2011-1 USD-2011-2
I thought I could do something like
#foreach( $c in $currencies ) <-- this will yield [EUR, USD,
JPY]
#foreach( $y in cur_${c} ) <-- this would have to give
[cur_EUR, cur_USD, cur_JPY]
$y.get_string(0)
#end
#end
but this will not work?
is there any way that the container in the #foreach statement can be the
concatenation of a literal and the result of a previous Velocity
variable interpretation?
