Class Summary

Class	Description
BIN	A BIN represents a Bottom Internal Node in the JE tree.
BINBoundary	Contains information about the BIN returned by a search.
BINDelta	BINDelta contains the information needed to create a partial (delta) BIN log entry.
BINReference	A class that embodies a reference to a BIN that does not rely on a Java reference to the actual BIN.
ChildReference	A ChildReference is a reference in the tree from parent to child.
CountEstimator	Estimates the number of non-deleted BIN entries between two end points, using information returned in TrackingInfo from Tree.getParentINForChildIN.
CountEstimator.KeyRatios
DeltaInfo	DeltaInfo holds the delta for one BIN entry in a partial BIN log entry.
FileSummaryLN	A FileSummaryLN represents a Leaf Node in the UtilizationProfile database.
Generation
IN	An IN represents an Internal Node in the JE tree.
INArrayRep<ARRAY_BASE_TYPE,REP_ENUM_TYPE,ELEMENT_TYPE>	The base class for the various array representations used by fields associated with an IN node.
INKeyRep	The abstract class that defines the various representation used to represent the keys associated with the IN node.
INKeyRep.Default	The default representation that's capable of storing keys of any size.
INKeyRep.MaxKeySize	The compact representation that can be used to represent keys LTE 16 bytes in length.
INLogContext	Extends LogContext to add fields used by IN.beforeLog and afterLog methods.
INLogItem	Extends LogItem to add fields used by IN.beforeLog and afterLog methods.
INTargetRep	The abstract class that defines the various representations used to represent an array of target pointers to children of an IN node.
INTargetRep.Default
INTargetRep.None	Representation used when an IN has no children cached.
INTargetRep.Sparse	Representation used when 1-4 children are cached.
Key	Key represents a JE B-Tree Key.
Key.DumpType
LN	An LN represents a Leaf Node in the JE tree.
MapLN	A MapLN represents a Leaf Node in the JE Db Mapping Tree.
NameLN	A NameLN represents a Leaf Node in the name->database id mapping tree.
Node	A Node contains all the common base information for any JE B-Tree node.
SearchResult	Contains the result of a tree search
TrackingInfo	Tracking info packages some tree tracing info.
Tree	Tree implements the JE B+Tree.
Tree.SearchType	Embodies an enum for the type of search being performed.
TreeLocation
TreeUtils	Miscellaneous Tree utilities.
VersionedLN	VersionedLN is used to provide an in-memory representation of an LN that makes its VLSN available through btree access.
VLSNCache	Caches the VLSN sequence for the LN entries in a BIN, when VLSN preservation and caching are configured.
VLSNCache.DefaultCache

Exception Summary

Exception	Description
CursorsExistException	Error to indicate that a bottom level BIN has cursors on it during a delete subtree operation.
LN.LNWriteFailureException
NodeNotEmptyException	Error to indicate that a bottom level BIN is not empty during a delete subtree operation.
SplitRequiredException	Indicates that we need to return to the top of the tree in order to do a forced splitting pass.
