Leveraging Scala Macros for Better Validation
16:30 - 17:20 Extra Spicy
Data validation is a common enough problem that numerous attempts have been made to solve it elegantly. The de-facto solution in Java (JSR 303) has a number of shortcomings and fails to leverage the powerful Scala type system.
With the release of Scala 2.10.x, a couple of experimental metaprogramming features were introduced namely: reflection and macros, which I'll be introducing in this talk by way of a practical example: implementing a full-blown data validation engine, utilizing def macros and a Scala DSL to enable elegant validator definition syntax and call-site.

In the last couple of years he's developed a major crush on Scala, promoting it within the Israeli software industry as part of JJTV (Java & JVM Tel-Aviv user group) and Underscore (Israeli Scala user group) and organizing the annual Scalapeño conference in Tel-Aviv.
