Support non-object-level functions/methods, as size and empty function
----------------------------------------------------------------------
Key: JEXL-29
URL: http://issues.apache.org/jira/browse/JEXL-29
Project: Commons JEXL
Issue Type: Improvement
Affects Versions: 1.1
Reporter: Weikuo Liaw
Priority: Critical
This needs an enhanced JexlContext, as suggested in the prev request, to work.
As configured validators in a validation form. It is nice for users to use
those validators directly such as "required(object)" or "requiredif(object, not
empty(object2))".
I have added "LOOKAHEAD(3) Method() " in the Reference() in Parse.jjt, so it
can be accepted but it needs changes to ASTMethod and JexlContext to work.
void Reference() : {}
{
(LOOKAHEAD(Identifier() "[" ( Expression() | IntegerLiteral() | Reference())
"]") ArrayAccess() | LOOKAHEAD(3) Method() | Identifier() )
(LOOKAHEAD(2) "."
