FeatureBuilder

Abstract Value Members

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.
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
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.
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.
