| Package | Description | 
|---|---|
| com.bigdata.btree | 
The  BTreeis a scalable B+-Tree with copy-on-write
semantics mapping variable lengthunsigned byte[]keys to variable
lengthbyte[]values (null values are allowed). | 
| com.bigdata.counters.store | 
    This package provides a persistence mechanism for performance
    counters. | 
| com.bigdata.journal | 
The journal is an append-only persistence capable data structure
supporting atomic commit, named indices, and transactions. | 
| com.bigdata.mdi | 
This package provides a metadata index and range partitioned indices
managed by that metadata index. | 
| com.bigdata.rdf.sail | 
This package contains the SAIL that allow bigdata to be used as a backend for
the Sesame 2.x platform. | 
| com.bigdata.resources | 
  This package provides the logic to managed the live journal and the
  historical journals and index segments for a  DataService. | 
| com.bigdata.service | 
This package provides implementations of bigdata services (metadata
service, data service, transaction manager service. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | AbstractBTree
 Base class for mutable and immutable B+-Tree implementations. | 
| class  | BTree
 This class implements a variant of a B+Tree in which all values are stored in
 leaves, but the leaves are not connected with prior-next links. | 
| class  | DelegateBTreeAn object that delegates the  IIndexandILinearListinterfaces. | 
| class  | IndexSegmentAn index segment is read-only btree corresponding to some key range of a
 potentially distributed index. | 
| class  | UnisolatedReadWriteIndex
 A view onto an unisolated index partition which enforces the constraint that
 either concurrent readers -or- a single writer may have access to the
 unisolated index at any given time. |
