Examples with DataOutputPlus org.apache.cassandra.io.util.DataOutputPlus used on opensource projects

Example 1 with DataOutputPlus

use of org.apache.cassandra.io.util.DataOutputPlus in project cassandra by apache.

the class RepairMessageSerializationsTest method serializeRoundTrip.

private <T extends RepairMessage> T serializeRoundTrip(T msg, IVersionedSerializer<T> serializer) throws IOException {
    long size = serializer.serializedSize(msg, PROTOCOL_VERSION);
    ByteBuffer buf = ByteBuffer.allocate((int) size);
    DataOutputPlus out = new DataOutputBufferFixed(buf);
    serializer.serialize(msg, out, PROTOCOL_VERSION);
    Assert.assertEquals(size, buf.position());
    buf.flip();
    DataInputPlus in = new DataInputBuffer(buf, false);
    T deserialized = serializer.deserialize(in, PROTOCOL_VERSION);
    Assert.assertEquals(msg, deserialized);
    Assert.assertEquals(msg.hashCode(), deserialized.hashCode());
    return deserialized;
}
