Class DataStructureFactory

java.lang.Object

com.github.basking2.sdsai.dsds.node.tx.DataStructureFactory

public class DataStructureFactory
extends java.lang.Object

Build transactional datastructures using Proxy. Any operation on BTree or PagedList or similar may result in several writes to the NodeStore. The TransactionalNodeStore collects those operations and executes them at one time. It also skips operations that are obviated by later operations. For example, writes are skipped if a delete happens later in the history. However, TransactionalNodeStore.commit() must be called manually. This set of factories proxy calls to data structures so that they may be wrapped with calls to TransactionalNodeStore.commit()}.
