Method Detail

writeNodeOrLeaf

protected long writeNodeOrLeaf(AbstractNode<?> node)

Description copied from class: AbstractBTree

Codes the node and writes the coded record on the store (non-recursive). The node MUST be dirty. If the node has a parent, then the parent is notified of the persistent identity assigned to the node by the store. This method is NOT recursive and dirty children of a node will NOT be visited. By coding the nodes and leaves as they are evicted from the AbstractBTree.writeRetentionQueue, the B+Tree continuously converts nodes and leaves to their more compact coded record forms which results in a smaller in memory footprint.

Note: For a transient B+Tree, this merely codes the node but does not write the node on the store (there is none).

Overrides:

writeNodeOrLeaf in class AbstractBTree

Returns:

The persistent identity assigned by the store.
