Subject [jira] [Commented] (OAK-34) Define query API
Date Tue, 03 Apr 2012 12:40:24 GMT

    [ https://issues.apache.org/jira/browse/OAK-34?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13245263#comment-13245263

Jukka Zitting commented on OAK-34:

Great stuff, thanks for pushing ahead on this! Comments:

* I'd drop the XPATH and SQL2 constants. They should instead be defined only in the specific
query parser components that implement these languages.
* Do we need getBindVariableNames()? If not, I'd just allow the client to pass whatever bindings
in the executeQuery() call.
* Instead of "Result" I'd use "Hits" or something similar to maintain a clear distinction
from the JCR API. But that's a minor detail.
* It would be more convenient to return an Iterable instead of an Iterator from getRows()
* We'll probably need a getSize() method to accompany getRows()
* Should it be possible for a column to be multi-valued?
* More generally, would it be useful to define result sets as a sequence of JSON- or tree-like
objects instead of using the more specific row abstraction? That would make it easy for us
to extend the query model later on and would allow us to reuse existing tools (JSON serialization,
etc.) designed for working with tree structures.

bindings, limit, offset, access rights. See OAK-28
