Questions tagged [salat]

Salat is a bi-directional Scala case class serialization library that leverages MongoDB's `DBObject` (which uses BSON underneath) as its target format.

The Salat project focuses on speed and simplicity of serializing case classes to and from target formats.

Salat is not a fully-fledged ORM and does not attempt to match the flexibility, compability or functionality of an ORM that would let you define relationships between classes, provide a query language, or serialize/deserialize every collection type known to Java or Scala.
