public class TestIncrementalWrite
extends AbstractBTreeTestCase

Test suite for the logic performing incremental writes of nodes and leaves onto the store. The actual timing of evictions from the HardReferenceQueue is essentially unpredictable since evictions are driven by AbstractBTree.touch(AbstractNode) and nodes and leaves are both touched frequently and in a data and code path dependent manner.

Methods

Modifier and Type	Method and Description
protected BTree	getBTree(int branchingFactor, int queueCapacity, int queueScan)
void	test_incrementalWrite() Test verifies that an incremental write of the root leaf may be performed.
void	test_incrementalWrite02() Test verifies that an incremental write of a leaf may be performed, that identity is assigned to the written leaf, and that the childKey[] on the parent node is updated to reflect the identity assigned to the leaf.
void	test_incrementalWrite03() Test verifies that an incremental write of a node may be performed, that identity is assigned to the written node, and that the childKey[] on the node are updated to reflect the identity assigned to its children (the dirty children are written out when the node is evicted so that the persistent node knows the persistent identity of each child).

Method Detail

getBTree

protected BTree getBTree(int branchingFactor,
             int queueCapacity,
             int queueScan)

test_incrementalWrite

public void test_incrementalWrite()

Test verifies that an incremental write of the root leaf may be performed.

test_incrementalWrite02

public void test_incrementalWrite02()

Test verifies that an incremental write of a leaf may be performed, that identity is assigned to the written leaf, and that the childKey[] on the parent node is updated to reflect the identity assigned to the leaf.

test_incrementalWrite03

public void test_incrementalWrite03()

Test verifies that an incremental write of a node may be performed, that identity is assigned to the written node, and that the childKey[] on the node are updated to reflect the identity assigned to its children (the dirty children are written out when the node is evicted so that the persistent node knows the persistent identity of each child).
