public class SerializationHeader
extends java.lang.Object

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	SerializationHeader.Component We need the CFMetadata to properly deserialize a SerializationHeader but it's clunky to pass that to a SSTable component, so we use this temporary object to delay the actual need for the metadata.
