Initial support for bitwise operators in Expression and SelectQuery
-------------------------------------------------------------------
Key: CAY-1693
URL: https://issues.apache.org/jira/browse/CAY-1693
Project: Cayenne
Issue Type: Task
Components: Core Library
Affects Versions: 3.1M3
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
It appears that most DBs support bitwise operations:
http://en.wikipedia.org/wiki/Bitwise_operation
http://dev.mysql.com/doc/refman/5.1/en/bit-functions.html
http://www.postgresql.org/docs/8.4/static/functions-math.html
I am going to add support in Expressions, SelectQueries and the underlying
stack for &, ~, |, ^... For now a very basic implementation with no parser
support, no ExpressionFactory support, and probably just MySQL adapter support.
It will stay under the radar, hopefully useful to people who need them until we
have the time to expand it to cover all DBs and all use cases.
