Hi
I have the following in a tree grammar that works as I expect:
columnNameList returns [List names]
: ^(COLUMN_NAMES ids+=ID+)
{
$names = new ArrayList();
for( Object tree : $ids ) {
$names.add(
((CommonTree)tree).getText().toUpperCase() );
}
}
;
What I am wondering is if there is a built in way in ANTLR to loop over the
list of ID tokens, to perform some common function, and then return that list.
I guess I am wondering if there is some built in 'collect' function similar to
the collect method that is available on collections in languages like Groovy or
Smalltalk.
I would prefer something like the following instead:
$names = $ids.collect{ it.text.toUpperCase() }
How is this usually handled?
