@InterfaceAudience.LimitedPrivate(value="Coprocesssor")
public class InternalScan
extends Scan

Special scanner, currently used for increment operations to allow additional server-side arguments for Scan operations.

Rather than adding new options/parameters to the public Scan API, this new class has been created.

Supports adding an option to only read from the MemStore with checkOnlyMemStore() or to only read from StoreFiles with checkOnlyStoreFiles().
