RowTransformer

class RowTransformer extends Transformer[Row, Table]

RowTransformer transform a Row to a Table whose values are all Tensor.

This transformer is a container of RowTransformSchemas. When this transformer being executed, it will run transform methods of its RowTransformSchemas.

Output of RowTransformer is a Table. The keys of Table are Tensor.scalar(schemaKey)s of included RowTransformSchemas. Correspondingly, the values of Table are results(Tensor) of RowTransformSchema.transform.
