Michael Hackstein 2a9c8ddc77 Merge branch 'devel' of github.com:arangodb/arangodb into MIT 2016-07-26 09:43:48 +02:00
Michael Hackstein 9b43dd30f0 Traversals now use Expressions to execute filter conditions. Right now V8 based conditions are non-functional. Also AqlValues do not work with base type of Transactions and do not need AqlTransactions. And so do expressions. Also allowed NARY_AND/NARY_OR in Expression nodes to be evaluated. 2016-07-21 16:38:32 +02:00
