Type Members

1. trait AlsoRegister[T] extends AnyRef

   

   Type-class for expressing dependent kryo-registrations that should go along with a given type T, e.g.

   Type-class for expressing dependent kryo-registrations that should go along with a given type T, e.g. when T's serialization/deserialization requires serde of other types.

2. case class ClassAndArray[T](cls: Class[T]) extends Product with Serializable

   

   Wrapper for a Class that should be directly kryo-registered, along with an Array-wrapped counterpart.

3. trait Registrar extends AnyRef

   

   Trait for encapsulating related sets of kryo-registrations.

   Trait for encapsulating related sets of kryo-registrations.

   The register method supports a variable number of Registrations.

   Can be used directly as a org.apache.spark.serializer.KryoRegistrator (see spark.Registrator and spark.Registrar) passed to a org.apache.spark.SparkConf / org.apache.spark.SparkContext, or can be mixed-in to e.g. companion objects of classes to record kryo-registrations required by the Spark operations in the corresponding class, and composed with downstream Registrars (see implicit conversion to Registration via Registration.registratorToRegistration) to track and reuse relevant groups of registrations.

4. sealed trait Registration extends AnyRef

   

   Base for (conveniently, implicitly) performing kryo-registrations given various kinds of inputs.

   Base for (conveniently, implicitly) performing kryo-registrations given various kinds of inputs.

   Class instances are the default / base case (and can come with an attendant implicit Serializer and related/required registrations via the AlsoRegister type-class), but Registrars and Registrators can be composed seamlessly as well for easy reuse of groups of registrations.
