Uses of BTree in com.bigdata.btree

Methods in com.bigdata.btree that return BTree

BTree	BTree.asReadOnly() Returns an immutable view of this BTree.
static BTree	BTree.create(IRawStore store, IndexMetadata metadata) Create a new BTree or derived class.
static BTree	BTree.createTransient(IndexMetadata metadata) Create a new BTree or derived class that is fully transient (NO backing IRawStore).

BTree	IndexSegment.getMutableBTree()

BTree	BTree.getMutableBTree()
static BTree	BTree.load(IRawStore store, long addrCheckpoint) Deprecated. by load(IRawStore, long, boolean) which specifies whether or not the BTree will be opened in a read-only mode and therefore allows for certain optimizations within the BTree constructor.
static BTree	BTree.load(IRawStore store, long addrCheckpoint, boolean readOnly) Load an instance of a BTree or derived class from the store.

This constructor is used when splitting the a root Leaf or a root Node.

UnisolatedReadWriteIndex(BTree ndx)
Creates a view of an unisolated index that will enforce the concurrency constraints of the BTree class, but only among other instances of this class for the same underlying index.
