All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`finish()`	This function is called when all tuples have been produced and passed to the tuple processor.
`void`	`process(Tuple tuple)`	Processes a single tuple generated from evaluating a query plan.
`void`	`setSchema(Schema s)`	This method is called once by the query evaluator before any tuples are passed to the `TupleProcessor.process(edu.caltech.nanodb.relations.Tuple)` method, so that the tuple-processor knows what the expected tuple-schema will be.
