Examples with Transaction javax.transaction.Transaction used on opensource projects

Example 11 with Transaction

use of javax.transaction.Transaction in project graphdb by neo4j-attic.

the class LockReleaser method dumpLocks.

// non thread safe but let exception be thrown instead of risking deadlock
public void dumpLocks() {
    System.out.print("Locks held: ");
    java.util.Iterator<?> itr = lockMap.keySet().iterator();
    if (!itr.hasNext()) {
        System.out.println("NONE");
    } else {
        System.out.println();
    }
    while (itr.hasNext()) {
        Transaction transaction = (Transaction) itr.next();
        System.out.println("" + transaction + "->" + lockMap.get(transaction).size());
    }
}

Example 12 with Transaction

use of javax.transaction.Transaction in project neo4j-mobile-android by neo4j-contrib.

the class LockReleaser method rollback.

public void rollback() {
    Transaction tx = getTransaction();
    // propertyIndex
    propertyIndexManager.rollback(tx);
    releaseCows(tx, Status.STATUS_ROLLEDBACK);
    releaseLocks(tx);
}

Example 13 with Transaction

use of javax.transaction.Transaction in project graphdb by neo4j-attic.

the class TestJtaCompliance method testSuspendResume.

     * the calling thread. o Tests that resume reinstate the transaction with
     * the calling thread. o Tests that an invalid transaction passed to resume
     * won't be associated with the calling thread. o Tests that XAResource.end

     * XAResource.start is invoked with TMRESUME when transaction is resumed.
     *

     * already associated with another thread. o Test if a suspended thread may
     * be resumed by another thread.
