well, those are actually just my thoughts how I think we should
implement the query enhancements specified in JSR 283.
there are basically three major blocks that we need to implement:
- JQOM, allows you to programmatically create a query
- JCR-SQL2, the new SQL query syntax
- additional query features (joins, etc.)
In a first step I already introduced temporary interfaces for the JQOM
and implementing classes.
I'd like to keep the current design of the query sub system for a
while until we are ready to switch to the new JQOM as the basis for
syntax independent query representation.
That is, in a first phase my suggestion is the following:
XPath---+
+--->AQT----+
SQL-----+ +---->LuceneQuery
|
SQL2------->JQOM----+
AQT: abstract query tree
And once the path SQL2->JQOM->LuceneQuery is stable:
XPath---+ AQT (deprecated)
|
SQL-----+---->JQOM----->LuceneQuery
|
SQL2----+
Comments and suggestions are welcome.
+1. Sounds reasonable. Do you want to use javacc for SQL2 parsing?
Looks good to me as well (sorry, somehow missed the original post).
