params - new transaction parameters

Returns:

new transaction

createTransaction

public Transaction createTransaction()

Description copied from interface: Persistence

Creates a new transaction in the main data store.

getTransaction

public Transaction getTransaction(java.lang.String store)

Description copied from interface: Persistence

Creates a new transaction if there is no one at the moment.

If a transaction exists, joins the current transaction. In this case:

• Subsequent invocation of Transaction.commit() does not affect current transaction.
• If Transaction.end() is called without previous Transaction.commit(), current transaction is marked as rollback-only, so any attempt to commit the surrounding Transaction will throw an exception.

Specified by:

getTransaction in interface Persistence

Parameters:

store - data store name

Returns:

object to control the transaction

Description copied from interface: Persistence

Returns existing or creates a new transaction-bound EntityManager, which will be closed on transaction commit/rollback.

Must be invoked inside a transaction.

Specified by:
