Abstract Value Members

  1. abstract def add(name: String, value: Double): Unit

    Add a single feature value.

    Add a single feature value. The total number of values added and skipped should equal to dimension in init.

  2. abstract def init(dimension: Int): Unit

    Initialize the builder for a record.

    Initialize the builder for a record. This should be called only once per input row.

    dimension

    total feature dimension

  3. abstract def newBuilder: FeatureBuilder[T]
  4. abstract def result: T

    Gather builder result for a result.

    Gather builder result for a result. This should be called only once per input row.

  5. abstract def skip(): Unit

    Skip a single feature value.

    Skip a single feature value. The total number of values added and skipped should equal to dimension in init.
