Subject [jira] [Commented] (CXF-5430) Support for OData query language
Date Wed, 04 Dec 2013 10:49:39 GMT

    [ https://issues.apache.org/jira/browse/CXF-5430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13838800#comment-13838800
] 

Sergey Beryozkin commented on CXF-5430:
---------------------------------------

I did a minor update to let custom parser be recognized and added a basic test showing how
a custom parser might adapt the custom expressions to CXF SearchCondition:
http://svn.apache.org/r1547752
(and r1547756)

So for POC we'd have a SearchConditionParser delegating to Olingo parser to get metadata representing
the expression (with single or several logical operators only for a start) and adapt it to
a primitive or composite CXF SearchCondition, hopefully it will work :-)

> Apache Olingo project (http://olingo.incubator.apache.org/) provides implementation for
OData (http://odata.org/).
> This task is about adapting OLingo URI Parser to CXF Search API.
> org.apache.cxf.jaxrs.ext.search.SearchConditionParser implementation will use Olingo
parser. The existing CXF Search visitors will be expected to work with both FIQL and OData
parsers.
> We may hit some limitations in the existing CXF Search API because OData is more sophisticated
language than FIQL. 
> At the moment I don't think it is realistic to support OData completely within CXF Search
API constraints. Most likely we will just settle for supporting the subset of OData queries,
with users being recommended to work directly with Olingo to get a complete support. Alternatively
we can try and enhance the search API if it proves feasible.
