All Implemented Interfaces:
ManagedScanFramework.ReaderFactory

public class BasicScanFactory extends Object implements ManagedScanFramework.ReaderFactory
Basic reader builder for simple non-file readers. Includes only schema negotiation, but no implicit columns. Readers are assumed to be created ahead of time and passed into the framework in the constructor.

This form is designed to simplify conversion of existing readers. While it provides a simple first step, readers should perform further conversion to create readers on the fly rather than up front.
