Method Detail

getBTree

public BTree getBTree(int branchingFactor,
             Journal journal)

Return a btree backed by a journal with the indicated branching factor. The serializer requires that values in leaves are SimpleEntry objects.

Parameters:

branchingFactor - The branching factor.

Returns:

The btree.

test_restartSafe01

public void test_restartSafe01()
                        throws IOException

Test basic btree is restart safe, including a test of BTree.removeAll()

Throws:

IOException

test_restartSafe_offsetBits

public void test_restartSafe_offsetBits()
                                 throws IOException

Test verifies that the journal can be correctly reopened when using a non-default value for offsetBits. The data on the BTree is verified in order to force reads from the last commit point on the journal after it is reopened.

Throws:

IOException

test_restartSafeCounter

public void test_restartSafeCounter()

Test verifies that the ICounter is restart-safe.

test_restartSafeSubclass

public void test_restartSafeSubclass()

Test verifies that classes which extend BTree are correctly restored by BTree.load(IRawStore, long, boolean).
