Interface ILocalBTreeView

All Superinterfaces:

IAutoboxBTree, ICounterSetAccess, IIndex, IIndexLocalCounter, IRangeQuery, ISimpleBTree

All Known Implementing Classes:

AbstractBTree, BTree, CommitRecordIndex, CommitTimeIndex, CounterSetBTree, EventReceiver.EventBTree, FusedView, IndexSegment, IndexSegmentIndex, IsolatedFusedView, JournalIndex, MetadataIndex, Name2Addr, ReadCommittedView, TxId2CommitTimeIndex

public interface ILocalBTreeView
extends IIndex

Interface indicates that the index is local rather than remote. A local index may consistent of either an AbstractBTree or a FusedView of AbstractBTrees.

Method Detail

getSourceCount

int getSourceCount()

The #of AbstractBTrees sources for the view. This will be ONE (1) if the view is a BTree.

getSources

AbstractBTree[] getSources()

An array containing the ordered sources in the view. Changes to the array DO NOT affect the view. If the view is an AbstractBTree then the array will contain a single element which is that AbstractBTree.

getMutableBTree

BTree getMutableBTree()

The BTree that is absorbing writes for the view.

Throws:

UnsupportedOperationException - if the index is not mutable.

getBloomFilter

IBloomFilter getBloomFilter()

Return the bloom filter.

Returns:

The bloom filter if one exists and otherwise null.
