Method Detail

newCursor

protected ITupleCursor2<String> newCursor(AbstractBTree btree,
                              int flags,
                              byte[] fromKey,
                              byte[] toKey)

Description copied from class: AbstractTupleCursorTestCase

Create an appropriate cursor instance for the given B+Tree.

Specified by:

newCursor in class AbstractTupleCursorTestCase

Returns:

An ITupleCursor for that B+Tree.

test_reverse_traversal

public void test_reverse_traversal()

test_reverse_with_branching_factor

public void test_reverse_with_branching_factor()

Stress test written in an attempt to find a spin lock in the reverse cursor traversal.

Note: This test was in the jetty branch. I have picked it up and copied it into the master. The version in the master should be preserved.
