Class SerializationHeader.Component

java.lang.Object

org.apache.cassandra.io.sstable.metadata.MetadataComponent

org.apache.cassandra.db.SerializationHeader.Component

All Implemented Interfaces:

java.lang.Comparable<MetadataComponent>

Enclosing class:

SerializationHeader

public static class SerializationHeader.Component
extends MetadataComponent

We need the TableMetadata 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.

Method Summary
