Enclosing class:

TestStoreScanner

private static class TestStoreScanner.CellGridStoreScanner
extends org.apache.hadoop.hbase.regionserver.StoreScanner

A StoreScanner for our CELL_GRID above. Fakes the block transitions. Does counts of calls to optimize and counts of when optimize actually did an optimize.
