This interface is used for serializing OrientDB datatypes in binary format. Serialized content is written into buffer that will contain not only given object presentation but all binary content. Such approach prevents creation of separate byte array for each object and decreased GC overhead. @author Evgeniy Degtiarenko, Andrey Lomakin
