Overview

Scan API

All operations are identical to Get with the exception of instantiation.
Rather than specifying a single row, an optional startRow and stopRow may be defined.
If rows are not specified, the Scanner will ierator over all rows.
You can constrain the scan to specific column families by calling addFamily for each family to retrieve on your Scan instance. Also u can call addCollumn for each column to retrieve.
To only retrieve columns within a specific range of version timestamps, call setTimeRange.
To only retrieve columns with a specific timestamp, call setTimestamp.
To limit the number of versions of each column to be returned, call setMaxVersions.
To limit the maximum number of values returned for each call to next(), call setBatch.
To add a filter, call setFilter.
U can use setLimit(int) to tell RS how many rows u want.
