Class Summary

Class	Description
BranchControlRow	A branch row contains key fields and the pointer to the child page.
BranchRow	Implements row which is stored in the branch pages of a btree.
BTree	A b-tree object corresponds to an instance of a b-tree conglomerate.
BTreeController	A b-tree controller corresponds to an instance of an open b-tree conglomerate.
BTreeCostController	The StoreCostController interface provides methods that an access client (most likely the system optimizer) can use to get store's estimated cost of various operations on the conglomerate the StoreCostController was opened for.
BTreeForwardScan	A b-tree scan controller corresponds to an instance of an open b-tree scan.
BTreeMaxScan	A BTreeScan implementation that provides the 95% solution to the max on btree problem.
BTreeRowPosition
BTreeScan	A b-tree scan controller corresponds to an instance of an open b-tree scan.
ControlRow	Base class for leaf and branch control rows.
D_BTreeController
LeafControlRow
OpenBTree	An open b-tree contains fields and methods common to scans and controllers.
SearchParameters	Parameters that are passed down during a recursive b-tree search.
WaitError	This error is never seen outside of the btree implementation.
