public class AbstractTestSegSplitter
extends TestCase2

Unit tests for splitting an index segment based on its size on the disk, the nominal size of an index partition, and an optional application level constraint on the choice of the separator keys. This approach presumes a compacting merge has been performed such that all history other than the buffered writes is on a single index segment. The buffered writes are not considered when choosing the #of splits to make and the separator keys for those splits. They are simply copied afterwards onto the new index partition which covers their key-range.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
protected static class	AbstractTestSegSplitter.MockPartitionIdFactory Mock implementation assigns index partitions from a counter beginning with ZERO (0), which is the first legal index partition identifier.
protected static class	AbstractTestSegSplitter.RejectSplitsAfterKey Accepts the recommended separator key unless it is GTE the key given to the constructor, in which case it refuses to accept any splits.
