final class BinarySequenceLambdaTransformer[I1 <: FeatureType, I2 <: FeatureType, O <: FeatureType] extends BinarySequenceTransformer[I1, I2, O]

Transformer that takes a single feature of type I1 and a sequence of features of type I2 and produces a single new output feature using the specified function. Performs row wise transformation specified in transformFn. This class should be extended when no parameters are needed within the transform function.

I1

input single feature type

I2

input sequence feature type

O

output feature type

    This method is used to make a copy of the instance with new parameters in several methods in spark internals Default will find the constructor and make a copy for any class (AS LONG AS ALL CONSTRUCTOR PARAMS ARE VALS, this is why type tags are written as implicit vals in base classes).

    This method is used to make a copy of the instance with new parameters in several methods in spark internals Default will find the constructor and make a copy for any class (AS LONG AS ALL CONSTRUCTOR PARAMS ARE VALS, this is why type tags are written as implicit vals in base classes).

    Note: that the convention in spark is to have the uid be a constructor argument, so that copies will share a uid with the original (developers should follow this convention).

    extra

    new parameters want to add to instance

    returns

    a new instance with the same uid
