Hi,
I have this model:
Examples:
'Examples:'
table=Table
;
Table hidden(WS, SL_COMMENT):
{Table}
(rows+=TableRow (NEWLINE rows+=TableRow)*)
NEWLINE?
;
TableRow:
{TableRow}
('|' (cells += TableCell ('|' cells += TableCell)*) '|')
;
TableCell:
name = Content
;
and this text:
Examples:
|h1|h2|h3|
|cell11|cell12|cell13|
|cell21|cell22|cell23|
I need to to assert that each cell has the corrected value.
Could someone point me how to do this with Xtend?
I tried the docs and know that exists IterableExtensions but couldn't find any example how to use it properly.
thanks in advance.
Cristiano

Hi Sebastian,
Thanks for the tip.
I've found an interesting example here.
And I'm trying this but can find a way to increment the counter.
val values = "h1,h2,h3&cell11,cell12,cell13&cell21,cell22,cell23".split("&")
if (!tableRows.nullOrEmpty) {
val i = 0
for(row: tableRows)
{
val rowCellValues = row.cells.map[name.toString].join(",")
assertEquals(values.get(i), rowCellValues)
i=i+1
}
}
There is a error being indicated in the "i=i+1" sentence.
can't I create local variable with xtend? how should I do that ?
thanks,
Cristiano

Cristiano,
The val keyword indicated final locals where you would use 'var' for
variable.
Please refer to the docs for details.
Best regards,
Sebastian
