Examples with TransBlob org.apache.jena.dboe.trans.data.TransBlob used on opensource projects

Example 1 with TransBlob

use of org.apache.jena.dboe.trans.data.TransBlob in project jena by apache.

the class TestRecovery method recoverBlobFile_2.

@Test
public void recoverBlobFile_2() throws Exception {
    String str1 = "Recovery One";
    String str2 = "Recovery Two";
    ComponentId cid1 = ComponentId.allocLocal();
    ComponentId cid2 = ComponentId.allocLocal();
    // Write out a journal for two components.
    {
        Journal journal = Journal.create(Location.create(dir.getRoot().getAbsolutePath()));
        journal.write(JournalEntryType.REDO, cid1, IO.stringToByteBuffer(str1));
        journal.write(JournalEntryType.REDO, cid2, IO.stringToByteBuffer(str2));
        journal.writeJournal(JournalEntry.COMMIT);
        journal.close();
    }
    Journal journal = Journal.create(Location.create(dir.getRoot().getAbsolutePath()));
    BufferChannel chan = BufferChannelFile.create(data);
    TransBlob tBlob1 = new TransBlob(cid1, chan);
    TransBlob tBlob2 = new TransBlob(cid2, chan);
    TransactionCoordinator coord = new TransactionCoordinator(journal, Arrays.asList(tBlob1, tBlob2));
    coord.start();
    ByteBuffer blob1 = tBlob1.getBlob();
    assertNotNull(blob1);
    String s1 = IO.byteBufferToString(blob1);
    assertEquals(str1, s1);
    ByteBuffer blob2 = tBlob2.getBlob();
    assertNotNull(blob2);
    String s2 = IO.byteBufferToString(blob2);
    assertEquals(str2, s2);
    assertNotEquals(str1, str2);
    coord.shutdown();
}

Example 2 with TransBlob

use of org.apache.jena.dboe.trans.data.TransBlob in project jena by apache.

the class TestRecovery method recoverBlobFile_1.

// Fake journal recovery.
@Test
public void recoverBlobFile_1() throws Exception {
    String str = "Hello Journal";
    ComponentId cid = ComponentId.allocLocal();
    // ComponentIdRegistry registry = new ComponentIdRegistry();
    // registry.register(cid, "Blob", 1);
    // Write out a journal.
    {
        Journal journal = Journal.create(Location.create(dir.getRoot().getAbsolutePath()));
        journal.write(JournalEntryType.REDO, cid, IO.stringToByteBuffer(str));
        journal.writeJournal(JournalEntry.COMMIT);
        journal.close();
    }
    TransactionCoordinator coord = new TransactionCoordinator(Location.create(dir.getRoot().getAbsolutePath()));
    BufferChannel chan = BufferChannelFile.create(data);
    TransBlob tBlob = new TransBlob(cid, chan);
    coord.add(tBlob);
    coord.start();
    ByteBuffer blob = tBlob.getBlob();
    assertNotNull(blob);
    String s = IO.byteBufferToString(blob);
    assertEquals(str, s);
    coord.shutdown();
}
