public class BTreeRedirectMarshaller
extends Object
implements org.apache.directory.server.core.avltree.Marshaller<BTreeRedirect>

Serializes and deserializes a BTreeRedirect object to and from a byte[] representation. The serialized form is a fixed size byte array of length 9. The first byte contains the magic number of value 1 for this kind of object and the last 8 bytes encode the record identifier as a long for the BTree.
