Examples with PreparedTransactionInfo org.apache.activemq.artemis.core.journal.PreparedTransactionInfo used on opensource projects

Example 1 with PreparedTransactionInfo

use of org.apache.activemq.artemis.core.journal.PreparedTransactionInfo in project narayana by jbosstm.

the class HornetqJournalStore method start.

public void start() throws Exception {
    journal.start();
    List<RecordInfo> committedRecords = new LinkedList<RecordInfo>();
    List<PreparedTransactionInfo> preparedTransactions = new LinkedList<PreparedTransactionInfo>();
