Package org.apache.derby.impl.store.access.btree

Interface Summary
BTreeLockingPolicy The generic.BTree directory wants to know as little about locking as possible, in order to make the code usuable by multiple implementations.
 

Class Summary
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 90% solution to the max on btree problem.
BTreePostCommit The BTreePostCommit class implements the Serviceable protocol.
BTreeRowPosition  
BTreeScan A b-tree scan controller corresponds to an instance of an open b-tree scan.
BTreeScanInfo This object provides performance information related to an open scan.
ControlRow Base class for leaf and branch control rows.
D_BTreeController  
LeafControlRow  
LevelInfo A BTreeDiag class is a "helper" class for the rest of the btree generic code.
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.
