    DataSerializer.writeVector(list, out);
    out.flush();
    DataInput in = getDataInput();
    Vector list2 = DataSerializer.readVector(in);
    assertEquals(list, list2);
}

Example 27 with DataInput

    for (int i = 0; i < array.length; i++) {
        assertEquals(array[i], array2[i]);
    }
}

Example 28 with DataInput

Example 30 with DataInput

use of java.io.DataInput in project geode by apache.

the class DataSerializableJUnitTest method testWriteObjectAsByteArray.

@Test
public void testWriteObjectAsByteArray() throws Exception {
    // make sure recursive calls to WriteObjectAsByteArray work to test bug 38194
    Object v = new WOABA();
    DataOutputStream out = getDataOutput();
    DataSerializer.writeObjectAsByteArray(v, out);
    out.flush();
    DataInput in = getDataInput();
    byte[] b2 = DataSerializer.readByteArray(in);

    ByteArrayInputStream bais = new ByteArrayInputStream(b2);
    DataInputStream dis = new DataInputStream(bais);
    Object v2 = DataSerializer.readObject(dis);
    if (!(v2 instanceof WOABA)) {
        fail("expected instance of WOABA but found " + v2.getClass());
    }
