-/**
- * A factory which allocates new transactions to operate on the data
- * tree.
- *
- * <p>
- * <b>Note:</b> This interface is not intended to be used directly, but rather
- * via subinterfaces which introduces additional semantics to allocated
- * transactions.
- * <ul>
- * <li> {@link AsyncDataBroker}
- * <li> {@link TransactionChain}
- * </ul>
- *
- * <p>
- * All operations on the data tree are performed via one of the transactions:
- * <ul>
- * <li>Read-Only - allocated using {@link #newReadOnlyTransaction()}
- * <li>Write-Only - allocated using {@link #newWriteOnlyTransaction()}
- * <li>Read-Write - allocated using {@link #newReadWriteTransaction()}
- * </ul>
- *
- * <p>
- * These transactions provides a stable isolated view of the data tree, which is
- * guaranteed to be not affected by other concurrent transactions, until
- * transaction is committed.
- *
- * <p>
- * For a detailed explanation of how transaction are isolated and how transaction-local
- * changes are committed to global data tree, see
- * {@link AsyncReadTransaction}, {@link AsyncWriteTransaction},
- * {@link AsyncReadWriteTransaction} and {@link AsyncWriteTransaction#submit()}.
- *
- * <p>
- * It is strongly recommended to use the type of transaction, which
- * provides only the minimal capabilities you need. This allows for
- * optimizations at the data broker / data store level. For example,
- * implementations may optimize the transaction for reading if they know ahead
- * of time that you only need to read data - such as not keeping additional meta-data,
- * which may be required for write transactions.
- *
- * <p>
- * <b>Implementation Note:</b> This interface is not intended to be implemented
- * by users of MD-SAL, but only to be consumed by them.
- *
- * @see AsyncDataBroker
- * @see TransactionChain
- *
- * @param <P>
- * Type of path (subtree identifier), which represents location in
- * tree
- * @param <D>
- * Type of data (payload), which represents data payload
