Abstract Value Members

  1. abstract def configureFields(fieldDescriptors: Seq[MarshallerFieldDescriptor]): Unit

    Permalink

    The datasource will call this method before emmiting records.

    The datasource will call this method before emmiting records. It will give a chance to the marshaller either to configure itself for accepting this sequence of name / type, or to check that the given sequence is compatible with type T.

    fieldDescriptors

    The list of fields the datasource will emmit.

  2. abstract def createOrReuseInstance(fieldValues: Seq[AnyRef], reuse: T): T

    Permalink

    The datasource will call this method each time a new record is available.

    The datasource will call this method each time a new record is available. It expect the marshaller to convert the list of values to an instance of type T. If T is not immutable, the marshaller is expected to mutate the reuse instance with the given field values. If T is mutable, the marshaller is expected to create an instance of its own.

    fieldValues

    the values emmited by the datasource

    reuse

    if not immutable, the instance to set values in and return

    returns

    the record of type T filled with the given values

  3. abstract def typeInformation: TypeInformation[T]

    The underlying type information.
