Re-work the S-RAMP->JCR query visitor using ModeShape JCR-JQOM -------------------------------------------------------------- Key: ARTIF-627 URL: https://issues.jboss.org/browse/ARTIF-627 Project: Artificer Issue Type: Enhancement Reporter: Brett Meyer Assignee: Brett Meyer SrampToJcrSql2QueryVisitor is extremely brittle and inflexible. See SRAMP-622 for an example. The following query is next to impossible: /s-ramp/xsd/XsdDocument[relWithAttr[s-ramp:getRelationshipAttribute(., 'FooKey') = 'FooValue' and @FooProperty = 'FooValue']] Note that the getRelationshipAttribute predicate function affects the relWithAttr *relationship* itself, while the @FooProperty check must go in the target artifact sub-query. Correctly handling this query will require a Builder pattern to be introduced. Attempt to use ModeShape's JCR-JQOM: https://docs.jboss.org/author/display/MODE40/JCR-JQOM Also switch to using an Antlr grammar ModeShape also has a builder class, but it's not public and may pose additional issues. {quote} (10:00:16 AM) rhauch: brmeyer: well, it's not public: https://github.com/ModeShape/modeshape/blob/master/modeshape-jcr/src/main... and https://github.com/ModeShape/modeshape/blob/master/modeshape-jcr/src/test... (10:01:39 AM) rhauch: brmeyer: that builder is somewhat limited, and it is really meant for hard-coded code. For example, there are places where you'd have to build strings (e.g., using "AS" for aliases) {quote}
