Processor extends Describable
Unlike a Transformer, receives the whole upstream generator, not one batch.
Methods
- bind() : BoundStep<string|int, Processor>
- breaks() : bool
- True when process() needs every input row before it emits one: the processor ends its pipeline.
- describe() : null|Description
- fromDescription() : static
- process() : Generator<string|int, Rows>
- Process a stream of Rows and return a new stream.
