Example 1 with CreateTableRequest

use of org.bboxdb.network.packages.request.CreateTableRequest in project bboxdb by jnidzwetzki.

the class TestNetworkClasses method encodeAndDecodeCreateTable.

/**
 * The the encoding and decoding of an create table package
 * @throws IOException
 * @throws PackageEncodeException
 */
@Test(timeout = 60000)
public void encodeAndDecodeCreateTable() throws IOException, PackageEncodeException {
    final short sequenceNumber = sequenceNumberGenerator.getNextSequenceNummber();
    final TupleStoreConfiguration ssTableConfiguration = TupleStoreConfigurationBuilder.create().withTTL(10, TimeUnit.MILLISECONDS).withVersions(666).withSpatialIndexReader("reader").withSpatialIndexWriter("writer").build();
    final CreateTableRequest createPackage = new CreateTableRequest(sequenceNumber, "test", ssTableConfiguration);
    final byte[] encodedVersion = networkPackageToByte(createPackage);
    Assert.assertNotNull(encodedVersion);
    final ByteBuffer bb = NetworkPackageDecoder.encapsulateBytes(encodedVersion);
    final CreateTableRequest decodedPackage = CreateTableRequest.decodeTuple(bb);
    Assert.assertEquals(createPackage.getTable(), decodedPackage.getTable());
    Assert.assertEquals(createPackage.getTupleStoreConfiguration(), ssTableConfiguration);
    Assert.assertEquals(createPackage, decodedPackage);
    Assert.assertEquals(createPackage.hashCode(), decodedPackage.hashCode());
